Perhaps the worldline was indeed trying to converge, but Ethan felt the primary reason was simply that "good advice can't save a ghost determined to die."
In the original timeline, Olunice died at the hands of Lady Aphreya—the very goddess he constantly fawned over—after descending to Earth out of jealousy for Basara Tojo. Now, the reason he died at Ethan's hands was much the same. Olunice was a rare type among angels—a mechanical angel with intense, carnal lust.
If only Chisato Hasegawa had defected from the God Realm, Olunice might have controlled himself, given Ethan's current terrifying strength. But Ethan had swept up all the goddesses of the God Realm in one go, leaving Olunice with nothing but a void. Combined with the news that Chisato and the others had their Godheads stripped—meaning their power had plummeted, likely below the Demon Lord level—it was too much for him. Without Ethan's dual cultivation ability, they truly wouldn't have been able to maintain their rank.
Driven by these factors, Olunice finally succumbed to his desires and risked his life to sneak into the human world, hoping for a chance to snatch the women back. And then... there was no "then."
Watching the green specks of light dissolve into pure magical energy, Ethan used a recording spell to capture the final moments and sent the image to Rias. Olunice's confession was documented perfectly; this evidence could be traded with the God Realm for some benefits. Although Olunice was a Demon Lord level being, he had violated the treaties first. His death was his own fault. Besides, the Ten Great Gods were busy picking new successors and wouldn't care about a rogue element causing trouble during the chaos. If anything, to minimize the mess, they would likely apologize and pay a price to settle the matter quickly.
Though Ethan preferred being a "hands-off" boss, he never missed an opportunity to gain leverage for his people.
After dealing with Olunice, Ethan stabilized the young teacher's fractured psyche and sent her to the school infirmary. He didn't care what her reaction would be when she woke up tomorrow morning. The school was empty now, so there was no worry of anyone taking advantage of her. He had already put the security guards into a magical slumber; it was much easier to knock people out beforehand than to wipe memories afterward.
As the last rays of the sunset faded, Ethan strolled out of Aisu Academy with his hands in his pockets. "Perfect timing. Before I go see little Nanao, I should stop by and pick up Chisato-nee."
With a step, the air rippled, and he appeared at Chisato Hasegawa's luxury apartment. While the grand mansion was big, there were honestly too many girls there. After their initial treatment, Chisato, Raphaelene, Frigga, and Sif—the four former goddesses—had moved into Chisato's apartment. They were familiar with each other and enjoyed exploring the human world together.
"Ethan, you're here," Raphaelene said, looking back with a smile. "Are you staying the night? Chisato and the others missed you."
Her strength had only recovered to S-class, but as the former strongest Valkyrie, she was the first to sense his arrival.
"Hmph, don't act like you didn't miss him too," Sif pouted as she approached. After countless sessions with Ethan unlocking every shameful position imaginable, she was still tsundere, but she didn't blush at every little thing anymore.
Raphaelene smiled gently, ignoring Sif's temper. "Of course I did. I'm just not as greedy as a certain someone."
Among the four goddesses, Sif was the most addicted to dual cultivation, followed by Chisato and Frigga, with Raphaelene being the most composed.
"Sorry, I can't stay the night," Ethan said, patting Sif's head. "I came to ask for Chisato-nee's help. I'll be leaving soon."
Ethan wasn't entirely sure how to permanently stabilize Nanao Tachibana's body, so he wanted Chisato—who had been monitoring Nanao for years—to guide the process.
"Is it about Tachibana?" Chisato asked, stepping out of the bedroom. She wore a pale green knit sweater and black lace garter stockings. Without her lab coat, her devilish, erotic curves were on full display. Combined with her naturally seductive face, Ethan found himself momentarily dazed despite having enjoyed her many times before.
Chisato felt a surge of joy at his gaze, though she kept her voice calm. "Is there something on my face?"
"No, you're just so beautiful I got distracted," Ethan replied honestly. "I plan to stabilize Nanao's state tonight and want you to guide me."
"I see. Since she's made her decision, we don't have to wait for her to turn eighteen."
The atmosphere between them was so thick that the other three felt like third wheels. "Alright, if you're leaving, then go. Stop showing off your affection here," Sif grumbled, giving Ethan a playful kick on the shin.
Ethan took Chisato's smooth hand, and they teleported directly into Nanao Tachibana's home.
Nanao lived alone; her parents had abandoned her long ago due to her True Ancestor bloodline. The sudden appearance of the two startled her. She hadn't awakened her bloodline yet, so her strength wasn't even A-class. Such high-level spatial magic was beyond her comprehension.
"Ethan-kun? Chisato-sensei?" Nanao relaxed once she recognized them.
Ethan greeted her and set up a barrier. Gasper wasn't there; the blond trap knew his place and avoided being alone with Nanao in private settings. Ethan appreciated Gasper's tact—if the boy were any less self-aware, his cute looks could easily lure girls into bed.
"Good evening, Ethan-kun, Chisato-sensei," Nanao said, her voice trembling with nerves.
Chisato spoke in a reassuring tone. "Nanao, go to your room and change. Leave the rest to Ethan."
"C-change? Into what?"
"Something feminine. A school sailor suit and feminine underwear."
The psychological suggestion of the clothes would help anchor her female identity. Nanao nodded and went to bathe first, wanting to be clean and wear her best "victory" lingerie for the occasion.
While she was away, Chisato explained the process to Ethan. "To stabilize her body, we must first fix her mental state. She needs to subjectively desire to be a woman as strongly as possible."
"How do we do that?" Ethan asked.
"She needs a strong emotional impact. Ideally, she should use her Evil Eye on herself to overwrite her own will from the root. It's like a controlled version of a hypnotic command."
Nanao's Evil Eye was a god-tier talent, capable of rewriting a person's essence. However, like Gasper, she couldn't control it yet. To use it on herself, she would need a mirror.
"Let's see if she's up for it. If not, we'll just start," Ethan said confidently. "I believe that once she experiences 'it,' she'll want to be a woman with all her heart."
When Nanao emerged, she looked troubled. She felt her desire to be a woman was already strong, but hearing it needed to be stronger made her anxious. "Should I try the Evil Eye?"
"If you're not confident, don't push it," Chisato said. "It's not strictly necessary."
Nanao immediately abandoned the idea, fearing a magical backlash.
"Then let's begin. But before that..." Chisato smiled mischievously and hooked her arms around Ethan's neck. "Let me give her a demonstration to help her set her mind."
Before Ethan could respond, Chisato's lips crashed onto his. It was a fierce, sudden kiss.
"Mmm? Chisato-nee...?" Ethan laughed, pushing her back slightly. "Shouldn't we focus on Nanao first?"
"Nanao needs to feel the joy of being a woman through you. If she watches us, her desire to be in my place will burn much hotter. Think about Mio and the others—don't they get more desperate for you when they see you with someone else?"
Ethan realized she was right. Watching others make love is stimulating, but when jealousy and envy are added to the mix, the fire of lust burns much brighter. For a girl like Nanao, who had suppressed her emotions for years, she needed a "lead" to follow.
"Can we continue?" Chisato whispered. "Watching me take you will make her crave her identity as a woman more than anything."
Ethan glanced at Nanao, whose face was already beet-red. "Fine then."
Ethan took the lead, pulling Chisato into a deep, passionate kiss. Their tongues danced and tangled as Chisato let out soft, needy moans. They began to strip each other with practiced ease—a result of their many "healing" sessions. Within seconds, the floor was littered with their clothes.
Chisato was left in only her panties and black lace garter stockings, while Ethan was down to his boxers. He pressed his swelling cock against her through the fabric.
"Ah! Mmm... haaa...!" Chisato ground her sensitive wetness against him, the sound of slick friction audible even through the cloth. She was already leaking a massive amount of honey.
Ethan didn't intend to go all the way with Chisato yet. Keeping her in a state of unfulfilled craving would heighten Nanao's anticipation and jealousy.
Chisato knelt before him, her red tongue darting out to lick his neck, chest, and stomach before reaching his waistband. She pulled his boxers down and immediately took his throbbing, iron-hard rod into her mouth.
"Mmmph... slurp... gluck... ahhh..."
She was a master now. Her warm, wet mouth engulfed him completely, her tongue swirling around the head with expert precision. Ethan rewarded her by stroking her hair with one hand and kneading her heavy breasts with the other.
Chisato moaned into him, sucking like a vacuum while rubbing her breasts against his thighs and fondling his balls. She was giving him everything to make him happy as a man.
In return, Ethan gave her the pleasure of being a woman. He grabbed her hair and began to thrust his hips, pulling her head onto his cock with dominant force. Every time he slammed into the back of her throat, Chisato's long black hair swayed like wings. Nanao watched from the side, her eyes wide, her breathing shallow and ragged as she witnessed the raw, carnal hunger of the woman she respected.
