In the depths of the Underworld, within the majestic fortress known as the Throne of the Maou, the atmosphere was dense, charged with a solemn and heavy aura. Shadows danced upon walls of onyx carved with ancient runes, while a spectral light emanated from floating candelabras that cast a faint bluish glow.
There, surrounded by a multitude of high-ranking demons and ancient advisors, stood Sirzechs Lucifer and the Maou Serafall Leviathan, along with the other Maou who governed the delicate balance of the demon world. Their faces showed a mix of determination and concern, aware of the weight upon their shoulders following the recent Fall and the latent threat that still loomed.
The great hall was arranged for an unprecedented meeting. In the center, seated upon a throne of dark wood and shining metals, was Odin, an imposing old man with a white beard and lively eyes that, despite his venerable appearance, revealed a mischievous spark. His white tunic adorned with runic symbols contrasted with his lopsided, roguish smile. Although his posture and presence emanated divine authority, rumors circulated among those present about his peculiar fondness: a well-known and legendary obsession with breasts, which he often manifested with comments and brazen looks when the occasion allowed.
However, that night, the old Norse god knew the situation demanded seriousness, and he set aside his usual antics to speak with a deep and grave voice that resonated throughout the chamber, capable of instilling respect and fear simultaneously:
"Maou of the Underworld, bearers of power and guardians of the balance: the supernatural world is in peril as never before. A threat has emerged, unleashing chaos and destruction in its wake. The Chaos Brigade, a terrorist group unknown to many, has broken into various pantheons, sowing death and disorder in mythologies we thought untouchable."
His eyes shone with contained fire as he scanned the room, gauging reactions.
"I have sent Azazel to contain this threat, but the magnitude of its actions exceeds what a single army can handle. That is why I come today seeking an alliance, a union between the Maou and Asgard to face this common threat."
Sirzechs frowned, his mind already working on the political and strategic implications.
"What guarantees do we have that this Chaos Brigade isn't a distraction? Or a pawn in the hands of greater enemies?"
Odin nodded, showing respect for the demonic caution.
"Your doubts are valid, Lucifer. The Brigade is enigmatic, and their goals are still unclear. But the destruction they have caused is tangible: Norse temples desecrated, Greek sanctuaries in ruins, and shadows emerging in sacred places. If we do not join forces, the consequences will be catastrophic."
Serafall, who had remained silent but attentive, spoke with her clear, firm voice:
"What do you propose, Odin? A military alliance? Information exchange? A diplomatic coalition?"
The Norse god responded with solemnity, though now and then his gaze strayed a bit towards some of the female figures present, causing an uncomfortable smile on more than one face.
"All of the above. We need a cooperation pact that includes intelligence exchange, coordinated deployment of forces, and the opening of diplomatic channels to react quickly. The Chaos Brigade understands no borders or loyalties; their attacks are unpredictable."
A murmur ran through the hall, for although everyone knew the common enemy demanded unity, the ancient rivalries between demons and Norse gods made full trust difficult.
Sirzechs crossed his arms, contemplating deeply before responding:
"This alliance could strengthen our control, but it also implies risks. Let us not forget that the politics between our worlds are fragile. However, the security of the universal balance is above our disputes."
"Then, with your approval, we will begin integrating our information networks and coordinate Azazel's movements with our forces here in the underworld," added Odin with a slight nod, while a mischievous smile touched his lips as he imagined future meetings with more "feminine comfort."
Serafall observed Sirzechs and then Odin, noting the seriousness in their gazes.
"If it is necessary to preserve order, the Sitri clan will be willing to cooperate. Furthermore, the Underworld's stronghold can serve as a refuge and operations center."
The meeting continued for hours, detailing technical and magical aspects of the collaboration, negotiating terms, and establishing protocols to keep the alliance strong and effective.
As it concluded, the hall was illuminated with a faint light, reflecting a silent hope for the future. The Chaos Brigade remained a threatening shadow, but for the first time in a long while, the powerful forces of the supernatural world were walking together... at least for now.
Sunday afternoon, the air in Kyoto had that clean smell of damp pine you only find after a light rain. With each step I took along the park path, memories from the summit of Tartarus returned like flashes of lightning: the roar of the wind, the dull ache in my stomach, the impossible gleam of a blue butterfly. Ddraig said nothing this time; he was just there, like a deep heartbeat keeping me company.
I crossed the clearing and, as always, the illusion gave way. The world folded in on itself, and I appeared before the hidden yōkai village. The guards—kitsune and tanuki—let me pass as soon as they recognized me. One joked that "today I smell more like dragon than last time." I laughed politely; truthfully, the comment pricked my conscience a bit: the transformation was still progressing slowly, and although Philemon had granted me an amazing recovery, I would occasionally get a sharp, burning twinge in my muscles and bones, as if something beneath my skin was learning to bend differently.
Yasaka was waiting for me at the entrance with that mesmerizing calm. A light kimono, her golden hair tied up in a high bun, and, like a fan of pale fire, her nine tails elegantly peeking from behind. She smiled before speaking; the kind of smile that disarms any defense.
"You came," she said, and only then did I realize how much I had needed to hear her voice.
We sat in the inner garden, on freshly aired tatami mats. The tea ceremony flowed like a river: mixing, pouring, offering. When she asked me to tell her what had happened "up there," I took a deep breath. The shadow of Nyx still felt heavy in my throat. I told her about Ryoji, the final ascent with SEES, the moment Tamamo fell unconscious and everything was reduced to a straight line between death and me. I didn't embellish anything. Nor did I seek heroics. I told her I was afraid; that at moments, the thought of not seeing them—all of them—again chilled me more than the void of the night.
Yasaka listened without interrupting. At times, her tails moved slowly, as if marking the rhythm of my story. When I finished, she reached out and gently moved aside the collar of my t-shirt on my left shoulder. The mark of her bite was still there, perfectly defined, the arcs of her fangs tracing a circle of new skin. Not even accelerated regeneration had been able to erase it.
"You kept it," she whispered.
I nodded. I didn't try to explain it too much; it wasn't just a symbol. It was a promise, a compass. Sometimes, when the pain of transformation rose like a tide, pressing the mark with my fingers cleared my mind.
"I didn't want it to disappear," I said. "It reminds me I have a place to return to."
She rested her forehead on my shoulder for a moment, breathing deeply. Then, almost automatically, her playful side emerged and she offered me an onigiri she had given "too much" attention to; each bite came with a "try this one" and "now this one." I ended up eating more than I should have, between laughs and small, affectionate scoldings.
"Dad!" Kunou's voice pierced the corridor like an arrow. "Come, come, it's ready!"
"Dad." I was getting used to it faster than I dared admit. She took my hand with that tender determination children have and literally dragged me to the backyard garden, where she had set up an obstacle course with ropes, low chairs, and a pole laid across as a hurdle. My legs were still heavy from the battle, but my reflexes were awake. We played "hunter and dragon": she ran ahead, I pretended to be clumsy; now and then, when I purposely let my guard down, Kunou shouted victoriously and tapped my back.
In a turn, I caught a glimpse of Yasaka watching us from the wooden lattice, leaning against it with that calm smile she rarely allowed herself. I looked at her a second too long and missed Kunou's next "trap"; I tripped on purpose and fell onto the grass with an exaggerated groan. Kunou ran over, first worried, and when I opened one eye and let out a laugh, she crossed her arms, feigning anger.
"Don't do that," she said, puffing out her cheeks.
"Alright, you're right," I ruffled her hair. "You caught me."
We played like that for a good while. Sometimes, in the middle of a race, a pain would prick behind my ribs—the adaptation, I assumed—and Ddraig would clear his throat in the back of my mind.
"Don't overdo it, kid. Bodies need truces too."
I know, I thought. But Kunou's laughter and Yasaka's gaze made it impossible to stop.
As evening fell, Ginji appeared to greet me. He reported that surveillance in the village had been strengthened after the purge of the infiltrators. He asked me—with that tone between serious and grateful—to let him know if I detected any "smell of chaos" again. I promised I would. Inside, Ddraig let out a brief chuckle.
"Now you're an official tracker, huh? All you're missing is the orange vest."
Quiet, I replied, and almost laughed out loud.
Dinner was a slow parade of flavors. Yasaka, stubborn about taking care of me, served dishes meant for recovery: clear broth with ginger, soft fish, steamed vegetables. Between bites, her hand would seek mine. I reciprocated without hurry, letting myself be carried by that shared silence where nothing needed to be explained.
"I'll come back after classes end on Monday," I said. "I'd like Tamamo to come too... if that's okay with you."
"Of course," she replied. "She is family too. And..." she glanced sideways at the mark on my shoulder, "don't forget to leave it exposed. If you cover it all the time, it itches more."
"Yes, ma'am," I joked.
Time became elastic, and yet, night caught up with us as quickly as always. In the doorway, before saying goodbye, Yasaka approached very slowly. There were no ceremonial words; just the touch of her forehead against mine and, after, a long, warm kiss that said everything neither of us wanted to break by naming it. When she pulled away, her fingers lingered on my cheek for a moment.
"Come back," she murmured.
"Always."
I crouched down to hug Kunou. She wrapped her arms around my neck and squeezed tightly.
"Will you bring sweets when you come back?" she asked, with that relentless seriousness of someone negotiating.
"With sweets and new stories," I promised.
"Deal," she smiled and planted a kiss on my cheek.
The path back to the hidden portal was brief. When I crossed, the cold night air of Kyoto jolted me awake. I walked to the station, with the city lights drawing a map of constellations at ground level. On the platform, waiting for the train to Kuoh, I checked my messages: Sona confirmed the class schedule and a bureaucratic reminder from the student council; Rias had sent a "let's talk tomorrow" without further context; Mitsuru inquired about my health with that impeccable courtesy that, by now, was starting to sound like genuine concern; Yukari left four stickers in a row and a "don't stay up late."
I boarded the train. The car was almost empty. I rested my head against the window and let the gentle rattling arrange my thoughts. Outside, the world slid by in blurry streaks of light. For the first time since the summit of Tartarus, I had the feeling that the thread connecting all my lives—human, dragon, SEES ally, fiancé to a demon, partner to a kitsune—wasn't breaking, but weaving something stronger.
"Don't let your guard down," Ddraig said, without harshness.
I won't. Tomorrow, classes would resume. There were assignments, training, paperwork, politics. And yet, the only thing that mattered at that moment was the persistent warmth on my skin where Yasaka had kissed me and the soft echo of a little girl saying "dad."
I closed my eyes. I let the tiredness do its work. I didn't dream of gods or falling moons. I dreamed of a garden, a low table, intertwined hands... and the sound of a small laugh running from one side to the other, asking for another round of "hunter and dragon."
When the loudspeaker announced "Kuoh, next station," I was ready. Monday, school, routine. The world kept turning. So did I. And if chaos insisted on knocking at the door, I knew who I was defending. That was enough.
The morning had that clean shine that only the start of a semester brings: fresh air, new backpacks, the murmur of voices in the hallways like a tide. I left the mansion still drowsy from last night's train; the house was still stretching when Alya, Hikari, and Hibiki waited for me at the door with smiles designed to dissolve any tension. Tamamo, in her spiritual form, floated to the side with the lunchbox wrapped in cloth—her ethereal form kept her unnoticed by others—and handed it to me with an amused bow that only she could pull off.
"I made you something for break," she said with that voice that seemed to wrap honey and wind. "Don't get the wrong idea, it's just out of concern."
I smiled and accepted the little box. The gaze of the three girls behind me said it all: they were delighted with every little daily gesture. Reynare had stayed home taking care of household chores (and, according to her, leaving everything in "absolute order"), so the trip would be peaceful: four plus Tamamo in spirit.
The walk to Kuoh Academy was a familiar parade. The leaves still clinging to the cherry trees tinkled as if they knew the routine: the same roadside, the same stairs, the same door with Sona always at her welcome post. Seeing me arrive, a small smile appeared on her face; I returned a warm and restrained greeting. Nothing ostentatious; at school, overly open gestures attracted looks. She responded with the discretion of someone who knows how to measure the moment.
Entering the classroom was like returning to a theater: old seats, a chalkboard with marks that never fade, the smell of new books and erasers not yet worn in. Some faces had changed—as always—but for the most part, everything was where it should be. I felt a slight tremor of my senses: my Observation Haki, sharpened by so many battles, gave me small signals of emotional movement around me—nothing alarming, more like a map of mood and attention.
Aika Kiryuu was there, with that brazen attitude that made her stand out: talkative, quick to joke; her personality filled the corner of the classroom like a lamp that doesn't turn off. You didn't need to know every detail of the old stories to realize her presence would bring playful chaos to the day. Yukari Takeba, on the other hand, looked at me as soon as I entered and averted her gaze with a soft blush. No surprise: the last month had been strange for everyone, and she was still processing the Dark Hour stuff as if she'd been given a page torn from the world.
The girls took their seats beside me as they did every morning: Alya to my right, Hikari and Hibiki to the left, forming that comfortable barrier I sometimes needed and that other times made me smile at the absurdity of the scene. Outside the classroom, the life of Kuoh could be heard: street vendors, students running, laughter. In the background, we filtered a sense of routine and security. That's what the heart wants when it decides to face chaos: normality, even if just for a few hours.
The math teacher entered with the solemnity of one who believes themselves a guardian of numbers. He introduced himself, explained the semester's structure, talked about exams, homework, and projects. Few things distract me as much as a good equation, so I allowed myself the pleasure of paying real attention. There was something relaxing about solving problems that have answers; it was therapy for a mind that had learned to fight the unexpected. Now and then, I raised my hand and answered a question, not to show off but because I liked the feeling that my brain was still functioning in a place where things followed rules.
Tamamo, still in spiritual form, positioned herself in a corner where she could observe unnoticed, and I noticed how her aura gave me a strange comfort: a constant presence, without needing words. Her contained magical energy didn't interfere in class, but her closeness was a reminder that I wasn't alone, not even though part of me was already sharpened for what was to come. Sometimes I saw her move a strand of hair in her ethereal form and I'd return a little smirk. She'd reply with a tiny gleam in her eyes and turn her attention back to the lesson as if it were the most natural thing in the world.
During break, as I opened my lunch, I noticed more subtle movements: a shadow at the edge of the courtyard, a faint hum that wasn't from insects. They weren't clear signs of danger—not yet—but my Haki doesn't fail when it comes to small irregularities. I left the little box on the table and took a couple of steps closer; the girls followed me like a chorus that needs no calling. Behind them, Aika approached with a mischievous smile, poking her finger into the lunchbox and saying something that only made the girls laugh and me twist my mouth with resigned indulgence.
Midday, as the teacher developed a lesson on functions and their applications, I received a small mental message from Ddraig—brief, mocking—about the emotional instability of the classroom and the need not to waste energy. I responded with the same mental telepathy, an exchange only we shared while chalk screeched on the blackboard. Having a dragon in my head has its advantages and disadvantages: private conversations at any hour, and direct warnings about when it's a good time to keep quiet.
I thought about what was coming: the canon of the story I knew was about to begin, my suspicions that the mixing of worlds wouldn't leave Kuoh untouched. Part of me felt restless—a buzz under the skin—but another part was grateful for every ordinary moment: the class, the laughter, the simple homework. That's what I was fighting to protect.
When the bell rang, the classroom burst into motion. Books, greetings, plans for the Occult Research Club, and promises of "see you this afternoon" filled the air. Sona watched me from her post at the door as I left, we exchanged glances, and without a word, we understood that routine was a fan of calm before the storm. I walked toward the exit with Alya, Hikari, and Hibiki by my side, Tamamo gliding silently behind, holding the leftover lunch for the midday meal.
In the hallway, Yukari caught up to me for a moment and, in a barely audible voice, asked me something about the last night in Tartarus. I replied with what was prudent: brief, honest, and with no more details than we had already shared. She nodded, but her eyes held the question she still didn't dare to ask. Aika watched us from a corner and made an exaggerated comment about how I owed her a rematch in some school betting game. Everyone laughed, not because we were carefree, but because laughing is the most human way of asserting that we still control something.
I left the school thinking about what was left of the day: training, reviewing, maybe finding a moment to talk with Tamamo about her spiritual form and its limits in public, and tonight—if all went well—meeting with Mitsuru, Akihiko, and Yukari to coordinate the next incursion into Tartarus. But for now, the priority was more humble: listening to the lesson, returning the homework notebook, and savoring the calm before the inevitable shifting of the board.
I walked with my companions to the cafeteria, with the feeling that the normality we built with small gestures was, in reality, a silent fortress. It was that routine—so simple and so fragile—that was worth protecting. And while doing so, beneath the surface, I remained alert: my senses on guard, my mind attentive to any vibration telling me that the story was about to start in earnest.
Yukari wasn't sleeping well. Since the night Tartarus trembled and the moon balanced on the edge of the world, something in her had changed: the feeling that everything was more fragile, priorities were rearranging themselves without permission, and at the center of this new compass was Daniel. It wasn't just admiration for what he had done at the summit—that was monumental, yes—but a strange, wet mix of gratitude, curiosity, and a warmth that tightened her chest when he smiled or glanced her way. Mitsuru had saved him from the Kirijo mess and, in the process, had discovered an unexpected tenderness; Yukari understood that, and more: she was starting to care for him in a way that made her feel clumsy, visceral, and, above all, nervous.
Mitsuru, for her part, was a fortress of logic with barely perceptible cracks. She had seen how Daniel behaved with everyone, the way he didn't hide his honesty and how, despite extraordinary circumstances, he tried to be normal. Mitsuru liked that—perhaps more than she cared to admit—but what truly held her back was prudence: she wouldn't leap into the abyss out of pride; she preferred to know the details before letting emotions take the wheel.
That morning at Kuoh, the school routine had its usual peace, but with cracks: conversations ending in silences, gazes lasting just long enough to leave a mark. Yukari approached Daniel with excuses: "Can you help me with a physics problem?", "Did you see the latest club assignment?"; small things that allowed her to talk without exposing herself completely. He accepted with the characteristic naturalness—a smile and a polite gesture—and Yukari walked away with her heart rattling in her chest.
However, the real entrance into "testing" Yukari was orchestrated by Hikari, Hibiki, and Alya, in the way only those three knew: subtle, playful, and a bit relentless. It wasn't malice; they were Sekirei standards for measuring compatibility. The tests seemed simple on the surface but cut to the bone:
1. **Patience Test:** Hikari had Yukari spend the morning helping with an "impromptu cleanup" in the Occult Research Club—moving books, cataloging records, enduring the barrage of Aika's comments—to see if she could keep up without complaining. Yukari, reluctantly at first, ended up laughing with them.
2. **Tenderness Test:** Hibiki organized a mini-game: Yukari had to prepare a small edible gift for Daniel without using a phone or external instructions, only with what she saw in the cafeteria kitchen. Initial clumsiness gave way to creativity, and the result was surprisingly sweet.
3. **Sincerity Test:** Alya, with her emotional intelligence, confronted her with direct questions about what she wanted, if she was willing to accept the unorthodox nature of Daniel's relationship, and how she would deal with jealousy and shared "property." Yukari blushed, answered with shaky honesty, and earned respect for doing so.
Each test left Yukari a little more confident but also showed her in an emotional showcase where Mitsuru, observing from a distance, couldn't help but smile with something resembling tenderness and a hint of wariness. She didn't act; Mitsuru was pragmatic and knew emotions weren't forged by tests, but seeing Yukari try gave her a new angle she didn't quite know how to categorize: admiration mixed with competitiveness.
Daniel, for his part, lived in two timelines. On the surface, he laughed with his girlfriends, joked with Ddraig in his head, answered questions in class, and attended light training sessions. Inside, however, restlessness wouldn't leave him alone: he knew the High School DxD canon well enough to know that an important point could reignite the narrative—the arrival of Asia Argento, the trigger that, in the story he knew, would set another series of events in motion. But the world he had landed in didn't obey intact pages without tears: characters were missing, rules were mixed, and the appearance of certain elements was uncertain. Would Asia appear? When? Under what conditions? Daniel pondered this during lunch hour, with Tamamo in spiritual form holding his bento and Ddraig murmuring bitingly useful comments about probabilities and strategy.
He trained in the afternoon with Tamamo: that session was more mental than physical. Tamamo, ever meticulous, asked him to work on the subtle coordination of his Observation Haki and his breathing—he shouldn't burn out in spikes, because stamina had been a scarce resource since the top of Tartarus. Daniel let himself be guided; he closed his eyes, felt Tamamo's energy like a soft blanket, and, with the dragon's instructions echoing in his mind, practiced brief bursts of focused concentration. Ddraig, who enjoyed seeing his host improve, jokingly threw him a challenge: "If you keep this up, you'll soon have the patience of Rennie (an unlikely reference) and end up taming a repentant demon." Daniel let out a low chuckle and continued.
The afternoon ended with a calmer scene: Yukari approached Mitsuru by mere chance, seeking advice; Mitsuru was cold at first, then warm and surprisingly frank and helpful. She told Yukari that if she truly wanted something, she needed to be honest with Daniel—clear, without dramatic butterflies—and that she shouldn't accept less than she deserved. The words sank in: Yukari left with a less impulsive and more strategic plan, which calmed her.
When night fell and Daniel's mansion shone with the warm lights of home, he allowed himself a moment of tranquility. The girlfriends were scattered in small activities: Hikari and Hibiki shared combat anecdotes, Alya corrected Reynare's pronunciation of a Russian phrase, and Mitsuru, at a distance, watched with a cup of tea in hand. Daniel thought about the possibility of Asia arriving in Kuoh. What if the story he knew started differently in this world? What if Asia didn't appear and the story took a different turn? The uncertainty weighed on him, but the same uncertainty reminded him why they fought: to protect the possibility that ordinary people would keep waking up every morning in a city that didn't dissolve into the night.
That night, Yukari sat on the dormitory rooftop overlooking the bay. The breeze cooled her face, and for a moment, the world's noise faded. She allowed herself to feel the fear, hope, and desire, all at once. She wouldn't take a reckless leap; Mitsuru had taught her the virtue of tactical patience. But she wasn't going to stay on the bench either. She took a deep breath, closed her eyes, and murmured a small resolution: "I'll try. With honesty and without drama. If he says no, at least I'll have been brave."
In his head, Ddraig threw a joking line to Daniel—"get your cape and hat ready, looks like more applicants are coming"—and Daniel, half-asleep, responded with a sleepy smile. Even with everything that was changing, there was something primal and beautiful in the normality they shared: the routine, the ridiculous tests, the contained confessions, the hands that intertwined by chance. That's why they fought, and that's why Yukari decided that tonight she would sleep with a new determination under her pillow.
Near the end of the day, a minor piece of news circulated the hallways: the school announced a possible exchange with a foreign town—a small notice, a list of names to be confirmed. No one paid it any mind except Daniel, who for a moment felt a tingle at the nape of his neck: a possibility that could—or could not—become the first step for Asia Argento to enter the scene. It was just a rumor, a note on a bulletin board; but for someone who knew that stories sometimes bend with a single presence, it was enough to maintain vigilance.
And so the day ended: Yukari with her plan in her pocket, Mitsuru with her mind on social and political equations, Daniel balancing between what he knew and what he had to discover, and the world, once again, holding its breath—because the story would continue, whether due to ancient causes or new encounters.
