[Tokyo Streets → Hikarigaoka Park, Early Evening — 6:47 PM]
The afternoon light had begun its slow surrender to dusk, painting the Tokyo skyline in shades of amber and rose. The air carried that particular crispness of early spring—cherry blossom petals drifting lazily on a breeze that smelled of fresh grass and distant takoyaki stands.
Riku stepped out of the apartment complex with a swagger in his stride, phone clutched in his hand like a holy relic. The screen glowed with beautiful, beautiful numbers.
¥200,000,000
Two hundred million yen. Deposited. Confirmed. His.
"Holy shit," he breathed, the words fogging slightly in the cooling air. His net worth had officially crossed into territory measured in billions of yen. The kind of money that characters in Kaguya-sama would wage psychological warfare over. The kind that would make even the Shinomiya family raise an eyebrow.
I could buy an entire city block with this.
Tokyo's economy ran on two engines these days—entertainment and real estate. Both were goldmines for anyone with the capital and connections to exploit them. But Riku wasn't about to rush into property investment. Not yet.
Once I've properly trained my little slut...
A smirk curled his lips. Hirose Yoru's twenty-times cashback multiplier would turn real estate speculation into a money printing machine. Why gamble with his own funds when he could use them on her and still profit astronomically from the returns?
As for the entertainment industry—that was Yukigami Nahiro's domain now. Let the future idol handle showbiz while he focused on more... personal acquisitions.
Two financial nuclear reactors, he mused, shoving his phone into his pocket. Even if every investment crashes and burns, I'll still come out drowning in cash.
The evening crowd had begun to thin as the rush hour exodus wound down. Salarymen trudged toward train stations with the defeated posture of men returning to loveless marriages, while high school girls in sailor uniforms giggled over phones displaying the latest gacha pulls.
Riku's path home took him past Hikarigaoka Park—a modest green space wedged between apartment towers, featuring the obligatory playground equipment and winding paths lined with cherry trees past their prime bloom.
The sound of children laughing drifted from the swing sets. Chains creaked rhythmically. A ball bounced somewhere out of sight.
And then—
"Shirou, maybe Yoru has... reasons she can't talk about?"
That voice. Female. Soft but insistent.
Riku's feet stopped moving before his brain caught up.
Near the playground, standing beneath the spreading branches of an old maple tree, two figures were engaged in what looked like an increasingly heated discussion.
One was Satou Shirou—that familiar mop of carefully styled hair, that insufferably handsome face that belonged on the cover of a shoujo manga. He stood with his arms crossed, jaw tight, radiating the energy of a protagonist who'd just discovered his love interest had a secret past.
The other...
Oh.
She was taller than her brother by a few centimeters, willowy in build but generously curved where it counted. A yellow short-sleeved top stretched across her chest, the fabric pulled taut enough that the cartoon smiley face printed on it had been distorted into something almost comical—eyes pulled wide, grin stretched into an oblong leer by the impressive volume beneath.
Her face was refined porcelain—an elegant oval tapering to a delicate chin, skin pale as fresh snow. Ink-black hair had been gathered into a neat bun at the nape of her neck, exposing the graceful column of her throat. Phoenix eyes, elongated and slightly upturned at the outer corners, gave her an air of perpetual appraisal. Willow-leaf brows arched with natural elegance above that analytical gaze. Her nose was small and pert, lips painted a muted rose color that reminded Riku of sweet red bean paste.
Those eyes held light like captured starlight—intelligent, observant, currently clouded with worry.
Satou Kiyo. Shirou's older sister.
The narrator's voice slithered into his consciousness like oil:
「You've discovered Satou Shirou and his sister Satou Kiyo engaged in conversation. The topic appears to concern Hirose Yoru. Today they dare to discuss YOUR woman—tomorrow they'll dare to strike you directly. As a proper villain, you cannot allow such disrespect to stand. You decide to wait until Satou Shirou departs, then confront Satou Kiyo alone. After all, you still hold leverage over her brother. She wouldn't want anything... unfortunate... to happen to him. All you need to do is—」
A torrent of absolutely degenerate suggestions followed.
You're really committed to the whole 'corrupting influence' bit, aren't you?
Riku ignored the narrator's increasingly creative scenarios and found a bench partially obscured by hedges. Close enough to observe. Far enough to avoid notice.
Let's see what my ability picks up.
He focused his attention on the siblings, letting the passive scan of 「Secret Explorer」 do its work.
The conversation continued—fragments reaching his ears.
"—don't understand why she's being so cold lately—"
"—Shirou, relationships have ups and downs—"
"—feel like she's hiding something—"
Ding.
The familiar notification chimed in his mind.
「Secret Explorer」 ACTIVATED
Two clues obtained.
Clue #1 — Satou Kiyo:
She left home in extreme haste this morning. So much haste, in fact, that her usual bear-print panties were left behind on her bedroom floor. She is currently going commando.
Note: Exposing this secret will induce overwhelming shame. Far more effective than any direct threat.
Clue #2 — Satou Shirou:
He has begun developing doubts about Hirose Yoru. Her recent emotional distance has left him feeling neglected and frustrated. Satou Shirou has decided to return home and continue "venting" to Hazuki Uta—his childhood friend.
Note: Satou Shirou has already begun positioning Hazuki Uta as a backup option. He has recently noticed that she is, quote, "actually pretty cute."
Riku's eyebrow twitched.
This guy...
On the surface, Satou Shirou projected the image of a devoted, earnest, pure-hearted boyfriend. The kind of male lead who would charge into danger to protect his love interest, who would confess his feelings in the rain while clutching a crumpled love letter.
But beneath that shounen protagonist exterior?
He's already shopping for replacements. And he thinks I'M the villain here?
The clue about Satou Kiyo, though...
That's useful.
「Satou Shirou! He walks the path of death! Hazuki Uta is your classmate—you absolutely cannot allow this worthless piece of trash to defile her! Your mind races, searching for solutions—」
「And then your gaze falls upon Satou Kiyo. A perfect plan crystallizes. You need only wait for Satou Shirou to leave, then claim his sister. Force her to call her brother using a... suggestive voice...」
Your plans are getting more elaborate. I'll give you that much.
The siblings' argument had escalated. Voices rose. Gestures became sharp and emphatic.
Satou Kiyo reached out, trying to grab her brother's sleeve—
Satou Shirou jerked his arm away with enough force to make her stumble.
"I don't want to hear it anymore!"
He stormed off without looking back, shoulders rigid with wounded pride, leaving his sister standing alone beneath the maple tree.
Yikes. Someone's in their flop era.
Riku watched as Satou Shirou's composure crumbled. She drifted toward the edge of the path, found a spot near the hedges, and slowly sank into a crouch.
Knees drawn to her chest. Arms wrapped around her legs. Face buried against her knees.
The picture of elegant misery.
Around them, the park emptied with the dying light. Office workers had completed their exodus. Dog walkers had retreated indoors. Even the children had been collected by their mothers, leaving the playground equipment to creak mournfully in the evening breeze.
Perfect timing.
Riku rose from his bench and began a casual approach.
His footsteps crunched softly on the gravel path—deliberately audible. Non-threatening. The sound of someone simply passing by.
Satou Kiyo's head lifted at the noise.
Those phoenix eyes were rimmed with red, lashes clumped with moisture, a delicate sheen of tears still clinging to cheeks that had flushed pink with emotion. She looked up at him with the wariness of a wounded animal—vulnerable but not yet defeated.
Her gaze found his face.
Recognition: none.
Assessment: in progress.
Riku knew what she was seeing—sharp features, strong jaw, the kind of carelessly handsome look that suggested either modeling contracts or trust funds. Certainly not the face of a random creep.
At least my looks are working in my favor.
"Satou Kiyo?"
She flinched at her own name.
Those elegant fingers rose to scrub hastily at tear-tracks. She pushed herself upright with as much dignity as could be salvaged, smoothing her yellow top and brushing invisible dust from her short skirt.
"Do we... know each other?"
Her voice had steadied. The tears were being ruthlessly suppressed. This was a woman accustomed to maintaining composure.
High guard. She's not going to make this easy.
Riku arranged his features into an expression of friendly surprise.
"Oh! Sorry, didn't mean to startle you. I'm Hayanui Riku—Shirou and I are good friends."
"Good friends?"
Suspicion sharpened her gaze. Those phoenix eyes narrowed fractionally.
"Shirou has never mentioned anyone by that name."
Damn. She's thorough.
「Despicable Orator」— ACTIVATED
The familiar surge of persuasive power thrummed through his vocal cords.
「Clumsy Performer」— ACTIVATED
Performance Target: 「Uncle from the Chii-chan's Development Diary」
Wait, what—
TEMPORARY BUFF ACQUIRED:
Speech and Actions — Intimidation +70
TEMPORARY BUFF ACQUIRED:
Irresistible Mild Aphrodisiac Effect (Requires Skin Contact)
WHAT.
Riku's mental processes screeched to a halt.
This was the first time 「Clumsy Performer」 had activated outside of a deliberate performance. He'd never quite understood its trigger conditions—unlike 「Despicable Orator」, which fired automatically whenever he engaged in threatening dialogue, the Performer ability had always seemed random.
And what the hell is the "Chii-chan's Development Diary"? Why does it have an uncle character whose whole deal is being intimidating and... and APHRODISIAC-PRODUCING?
What kind of doujinshi did that come from?!
"Are you alright?"
Satou Kiyo's voice cut through his spiral. She was studying him with the same suspicious attention, head tilted slightly.
Right. Focus.
Riku moved.
His hand shot out—fast, precise—and closed around Satou Shirou's slender wrist.
"Ah—!"
The gasp that escaped her lips was involuntary, surprise momentarily overwhelming caution. Her wrist felt delicate in his grip, skin soft and warm, pulse fluttering beneath his fingertips like a trapped bird.
"Wh-what are you—"
Her voice had changed.
The cold composure was melting. The sharp edges were softening. What emerged was something almost... cute. Breathy. Uncertain. The voice of a girl, not a woman.
The aphrodisiac effect.
Satou Shirou's free hand rose as if to push him away, but the motion was weak. Token resistance. Her cheeks bloomed with color—not the blotchy red of crying, but a delicate pink that spread across her cheekbones like watercolor.
"You... you're..."
Her phoenix eyes had gone slightly unfocused. Lips parted. That elegant poise crumbling into something far more vulnerable.
Holy shit. This ability is BROKEN.
"Let's talk over there," Riku said, nodding toward a bench deeper in the park, shrouded by hedges and increasingly dense shadows. "Somewhere more private."
He maintained his grip on her wrist as he began walking.
She followed.
No resistance. No protest. Just the soft padding of her footsteps and the quickened rhythm of her breathing.
「Shameless Thief」 requires specific conditions—no interruptions, quiet environment, an intimate atmosphere...
The bench was wrought iron, painted forest green, positioned in a small alcove created by carefully trimmed hedges. A nearby lamp had burned out, leaving the area in comfortable dimness. The last golden rays of sunset filtered through the trees, dappling everything in amber and shadow.
Perfect.
He guided her to sit, positioning himself close enough that their knees almost touched. His hand remained locked around her wrist.
"Ah..." A small, pained sound escaped Satou Shirou's lips. She twisted her wrist slightly in his grip, the motion causing her chest to shift beneath that stretched yellow fabric. "You're... hurting me..."
The complaint came out soft. Almost plaintive. A far cry from the composed woman who had questioned him moments ago.
Riku didn't release her.
The aphrodisiac effect requires maintained skin contact.
"Satou Kiyo-san." He let his voice drop lower. More intimate. "I have a question for you. And I'd appreciate an honest answer."
He leaned closer.
She didn't pull back.
Her perfume reached him—something light and floral, jasmine perhaps, underlaid with the warmer scent of her skin. This close, he could see the rapid flutter of the pulse in her throat. The slight tremor of her lower lip. The way her pupils had dilated despite the fading light.
"Wh-what question...?"
Her voice was barely above a whisper.
Riku brought his lips to her ear.
Close enough that his breath ghosted across the sensitive shell.
Close enough to smell the faint shampoo scent clinging to her hair.
And he whispered:
"I know you're not wearing anything underneath."
「Shameless Thief」— ACTIVATED!
