For the rest of the afternoon, intermittent moans, pleas for mercy, and the sound of whipping echoed through the closed door.
"Ah! Bastard… no, don't pull the zipper on my pants—!"
"No… not that thing… no!"
"Please… stop… ah!"
"I was wrong… Master… spare me… oh oh oh!"
Mixed among them were Mosquito Girl's hesitant questions:
"Is this right?"
"Am I being too rough?"
Fubuki, Lily, and Sikes sat stiffly on the sofa, their faces growing redder by the minute.
Fubuki pretended to study Mosquito Girl's test paper, but the pencil in her hand had already snapped in two. Lily lowered her head, twirling her hair—her earlobes so red they looked like they might bleed.
And Sikes… she kept pushing up her glasses again and again, as if that gesture could somehow conceal her embarrassment.
She knew exactly what Kaito was doing. His "lesson" to Do-S was meant as a warning—kill the chicken to scare the monkey. If Sikes ever stepped out of line, she knew who would be next inside that room.
By evening, the bedroom door finally opened.
Kaito walked out looking refreshed, followed by Mosquito Girl, who was flushed and sweating, her expression dazed yet oddly satisfied.
Do-S still hung from the ceiling, swaying gently with a vacant look in her eyes.
"From now on," Kaito said to Mosquito Girl—deliberately loud enough for everyone in the living room to hear—"if that woman ever disobeys you again, just educate her the way I taught you."
"Y-Yes, Boss…" Mosquito Girl stammered, her cheeks burning. The "lesson" Kaito had given her had clearly opened a whole new world in her mind.
Fubuki glanced toward the bedroom door suspiciously. "She… wasn't broken, was she?"
"Don't worry," Kaito said with a grin. "She's fine. She just needs a little time to adjust to her new role."
Just then, the communicator on his waist began to vibrate urgently.
Kaito pulled it out, and a message from Agoni flashed across the screen:
[Emergency]
The 'Earth Defense Special Unit' inauguration ceremony held at Association Headquarters this afternoon was attacked.
A man calling himself a "Human Monster" not only defeated all the D-class fighters we deployed but also destroyed the Saitama mech piloted by Child Emperor.
The kid's emotions are unstable. Please check on him when you can…
Kaito frowned slightly and swiped through the attached photos.
A young man with silver hair and crimson eyes was laughing maniacally while standing atop the wreckage of the mech. The scars on his face and those feral eyes left no doubt—Garou.
"So it's Bang's rebellious disciple," Kaito murmured, sighing. "Another troublemaker."
Sliding the communicator back into his pocket, he turned to the women in the living room.
"I'm heading out. Don't wait for me for dinner."
He knew he'd have to deal with Garou sooner or later, given his friendship with Bang. But for now, the priority was checking on his loyal supporter—the brilliant but fragile Child Emperor.
Y City – Child Emperor's Private Laboratory
Nestled within a grove of cherry blossoms, the pristine white building glowed brightly under the evening sky.
Ding-dong.
Kaito pressed the doorbell and waited. After a moment, the sharp rhythm of high heels approached from within—quick but graceful.
With a soft click, the door opened.
Standing before him was a breathtakingly beautiful woman, perhaps in her early thirties. Her tailored office attire perfectly outlined her elegant figure. Beneath her fitted skirt, long legs encased in black stockings stood poised on seven-centimeter stiletto heels, adding to her commanding presence.
Most striking was the small tear mole at the corner of her left eye, lending a touch of alluring charm to her otherwise dignified face.
"P-please… may I ask who you are…?"
The beautiful woman's polite greeting halted abruptly the moment she recognized the visitor. Her pupils widened, her red lips parted, and her slender, well-kept hand instinctively moved to her chest.
"K-Kaito?!" she gasped. Her voice shot up several octaves, her eyes sparkling with the unmistakable light of a fan meeting her idol.
Kaito gave a polite nod. "Good evening, Madam. I apologize for the sudden visit. I've come to check on Isamu."
"Oh my goodness—it really is you!" the woman exclaimed, her cheeks flushed with excitement as she hurriedly stepped aside. "Please, come in! I'm Isamu's mother, Chishima Saori. You can just call me Saori!"
As she bent down to fetch slippers, the low neckline of her blouse revealed a glimpse of smooth, fair skin. Kaito's eyes flicked briefly in that direction before he looked away.
It was clear that this single mother took good care of herself—her figure was more alluring than that of many women in their twenties.
"Isamu often talks about you," Saori said as she led him inside, her voice trembling with excitement. "He says you're his most admired hero!"
Her admiration was as transparent as her son's. Clearly, Child Emperor's fandom for Kaito didn't come out of nowhere.
They walked through a meticulously kept Japanese-style garden, where Kaito noticed several Transformers models stacked neatly in a corner—relics of a younger Child Emperor's passion for machines.
Saori followed his gaze, her expression softening with maternal affection.
"That child has loved machines since he was little," she said quietly, then lowered her voice with concern. "Mr. Kaito, Isamu locked himself in his lab as soon as he got home today. He hasn't even eaten dinner… Did something happen?"
"Just a minor setback at work," Kaito replied calmly. "Boys need challenges—they build character."
Saori still looked worried but nodded, leading him to the basement.
Beside the heavy metal door, a blue iris scanner flickered to life.
"This child… even his own mother needs clearance to get in," she muttered helplessly before leaning in for the scan.
A soft beep sounded, and the reinforced door began to slide open with a hiss.
At once, a sharp smell of solder and machine oil filled the air.
Inside, the bright lights of the lab illuminated a small, determined figure standing on a raised platform—Child Emperor, focused intently on welding a delicate component.
His normally tidy brown hair was a tangled mess, and his white lab coat was streaked with oil. He'd clearly been at it for hours.
"Damn bastard…" the boy muttered under his breath, his childish voice shaking with fury. "Saying 'I don't hit kids'? My mech isn't trash!"
He slammed his small fist onto the workbench. Metal parts rattled in protest.
"Just you wait! Next time, I'll show you the power of my railgun!"
Saori took an anxious step forward, but Kaito gently stopped her, shaking his head.
He motioned for her to leave. Once the blast door sealed shut behind her, Kaito deliberately made his footsteps heavy against the metal floor.
"I told you not to bother me!" Child Emperor snapped, not even glancing back, the blue glow of his welding torch casting sharp shadows across the lab.
"You don't even welcome me?" Kaito said casually, leaning against the doorframe, his tone calm but teasing.
