In the morning, Izumi Nogami woke up before Kazuma. The first thing that entered the girl's sight upon opening her eyes was his tent, once again pitched. Yes, standing tall like a pillar.
"..."
"This guy has way too much energy…"
Miss Izumi pouted as she leaned closer to look at the boy's face. His sleeping expression was calm and peaceful, which finally put her at ease. "He should be fine. It's probably just a normal reaction. Maybe that scoundrel is dreaming about beautiful women."
Izumi Nogami muttered sourly, then quickly shook her head, trying to chase away the dangerous thought of giving him a "good morning bite." It was far too frightening. How could such a thought come to her so naturally? She really needed to calm down.
The girl put on her Bamboo-copter and flew away.
Today was Monday.
A new week had begun. Kazuma changed his shoes at the locker and followed the flow of students upstairs. When he woke up earlier, Miss Izumi was already gone, leaving one question lingering in his mind.
"How did I fall asleep yesterday?"
Thinking back on it now, even he found it strange. How could he have fallen asleep while Miss Izumi was sucking his cock?
Still, the sensation at the time had only been average. Kazuma clearly remembered that his body had been undergoing evolution. His entire body felt as if it were burning, so that kind of activity hadn't felt as comfortable as usual.
And even now, the heat hadn't faded.
"Miss Izumi probably ran off because she was embarrassed."
Kazuma chuckled softly, then quietly checked his condition again. The genetic mutation and evolution still hadn't stopped. He clicked his tongue inwardly.
"I only shone for five seconds, and this evolution has already lasted an entire day!"
And there was still no sign of it ending.
"Kazuma, good morning~"
After not seeing him all weekend, Akane Nanao rushed toward him the moment she arrived and threw herself into his arms, hugging him tightly without caring about the curious stares from their classmates.
"Meow~ Meow!"
The kitten followed, leaping into Kazuma's clothes with practiced ease—only to jump out again the next second as if it had been burned.
"How was your weekend? Fuyuka-senpai said you stayed at a beautiful older sister's house?" Akane Nanao placed her bento on Kazuma's desk and smiled brightly. That was also why she hadn't gone to the Old School Building. "I heard her charm even made Fuyuka-senpai feel pressured. When can I meet her?"
"Ahem… if there's a chance, we'll talk about it then," Kazuma replied, suspecting a hint of teasing behind her words. Yet Akane's expression remained gentle and sincere.
Right after her, Kanna Hiiragi rushed over and, without hesitation, launched herself into him with a full-force chest tackle. Pressed against the wall, Kazuma nearly lost his breath as he was buried in her soft embrace, a faint milky scent filling the air.
"Kazuma, I haven't seen you for two days—I missed you so much~~"
Kanna rubbed against him affectionately, completely unconcerned about anyone watching.
"Wuwuwu———"
"You two really are close," Sakurazawa Tomomi said as she walked over, her eyes filled with envy. She wanted to hug him too, but her relationship with Kazuma wasn't as close as Kanna's or Akane's.
Still, when it came to figure and charm, she was confident she wasn't lacking.
Sakurazawa Tomomi subtly puffed out her chest, comparing herself in secret.
Not only am I bigger, but I can produce milk too. Hmph, I win!!!
They've gotten a bit bigger lately… I'll ask Kazuma-kun to help massage them later.
Soon, Saki Yoshida arrived together with her two close friends, Minako Sanada and Sae Hinata. The trio of gyarus had gathered—but their leader was missing.
Izumi Nogami was nowhere to be seen.
Minako Sanada smiled and waved, while Sae Hinata immediately asked, unable to hold back, "Kazuma-kun, have you seen Miss Izumi?"
"How would I know?" Kazuma replied, his face slightly flushed as he struggled to free himself from Kanna's embrace.
"I saw you two together all weekend, right? I feel like you're hiding something from me."
"Eh? Really?" Kanna Hiiragi and Akane Nanao both looked surprised. Although they knew Izumi Nogami wasn't hostile toward Kazuma, spending an entire weekend together naturally invited speculation.
In just two days, their relationship seemed to have grown much closer.
Sae Hinata continued talking, completely unaware that the person she was discussing had already appeared behind her.
"Sae, were you just talking about me?"
"Wah! Miss Izumi, you scared me to death———"
Izumi Nogami narrowed her eyes slightly. "What? Are you that curious about my secret with Kazuma?"
A dangerous aura emanated from her, causing Sae Hinata and the others to lower their heads awkwardly. That was Miss Izumi's presence.
"Don't ask about things you shouldn't," she said coldly. Then her gaze shifted to Kazuma, and her expression became slightly unnatural. Perhaps recalling what had happened the previous night, she took a brand-new phone from her backpack and handed it to him.
"Here. A gift."
"Eh?"
"Don't misunderstand. I just thought it would be inconvenient if we couldn't contact you since you don't even have a phone," she said, trying to sound casual. She had gone out early that morning specifically to buy it.
Minako Sanada and Sae Hinata stared at her in disbelief. Miss Izumi actually bought Kazuma-kun a gift?
Meanwhile, Akane Nanao and Kanna Hiiragi felt a quiet sense of regret.
Ugh, why didn't I think of that first? Even if my allowance isn't much, buying a phone would've been possible. Now that gyaru's favorability has gone up a lot.
Darn it.
"A gift? That's really thoughtful. Then I won't be shy about accepting it."
Seeing that he didn't refuse, Izumi Nogami curled her lips slightly, clearly in a good mood.
Tazaki, sitting in front of them, felt completely numb. This woman would punch and kick him without hesitation, yet she bought Kazuma a gift. And on top of that, so many beautiful girls were gathered around him.
Was the difference between people really this big?
The once unnoticed corner of the classroom had now become the center of attention.
Beautiful girls surrounded Kazuma, each carrying a different fragrance. With their soft figures moving so close to him, his face grew redder and redder. It wasn't embarrassment—his evolving body seemed to be reacting to the stimulation, the heat rising sharply again.
As he listened to their lively chatter, Kazuma felt slightly dazed.
"Um… could you move aside?"
Chizuru Shiina stood behind the group, looking slightly troubled by the blocked path. When everyone turned to her, she spoke calmly. "Teacher Shirakawa wants to see you in the office, Kazuma."
She was simply delivering a message.
"Teacher Shirakawa?" The girls stepped aside, allowing Kazuma to finally see her clearly. "What does she want with me?"
"I don't know."
Her tone remained as cool and composed as ever.
"Alright, got it," Kazuma said as he stood up. "I'll head over now."
But in the very next moment, the calm and composed Chizuru Shiina suddenly gasped.
Not only her—Minako Sanada and the others nearby widened their eyes as well. The entire classroom instantly fell silent.
Kazuma froze, then slowly lowered his head.
When he noticed the obvious bulge beneath his pants reflected in everyone's stunned expressions, he was momentarily speechless.
The classroom fell into complete silence.
Anyone could tell from its outline how exaggerated it was. It wasn't merely large—it carried an overwhelming sense of presence, as if it were about to break free at any moment. The sheer pressure of it made Chizuru Shiina instinctively step back several paces.
The usually cold and aloof honor student finally lost her composure, her face flushing bright red.
"Y-you… you, you…"
Her words tangled together as she failed to finish her sentence.
The girls covered their mouths—some shocked, some embarrassed, some staring in disbelief. A few even froze, unconsciously swallowing.
The boys, on the other hand, clenched their teeth, eyes bloodshot, all thinking the same thing.
Is that guy even human?
Kazuma standing up had plunged the classroom into dead silence.
He had already caused a stir before by playing with a snake—but this time, it seemed he was about to make an even bigger scene.
Back to school on a Monday, and things were already this explosive?
Even Akane Nanao and the others couldn't help feeling embarrassed, a sense of shame rising in their hearts. Covering their eyes with their fingers, they said, "Kazuma, we're still in the classroom. Try to restrain yourself a little."
The problem was that Kazuma couldn't control it at all. He had already forgotten about embarrassment. His body kept growing hotter, and he hadn't expected the effects of the evolution to be this intense.
Izumi Nogami, however, immediately sensed that something was wrong.
"Are you okay?" she asked, quickly grabbing Kazuma's hand. "You're burning up—"
It had happened once last night, and now it was happening again?
"Eh?"
Kanna Hiiragi and the others hurried over anxiously. "Kazuma, your face is so red?!"
"I'm fine."
"How could you possibly be fine?" Izumi Nogami said firmly, pulling his arm without hesitation. "To the infirmary."
"What about Teacher Shirakawa…" Chizuru Shiina stared blankly at Kazuma as he was surrounded by the others.
"Move! Can't you see Kazuma isn't feeling well?" the gyaru snapped impatiently. The class representative always lectured her, and now she was getting in the way. She pushed Chizuru Shiina aside.
"Wait, we're coming too!"
Kanna, Nanao, and Sakurazawa Tomomi followed after them. Once they left, the classroom fell into an uneasy silence. The girls exchanged looks before quietly whispering among themselves, their expressions complicated.
Fragments of words like "so big" and "unbelievable" could faintly be heard.
Shinomiya Natsuha sat at the back with her chin resting in her hand, listening to the hushed conversation. "Is he sick?"
"But it really was big," she muttered under her breath, swallowing unconsciously. "Even when he's sick, it's that exaggerated. He really is a monster."
After speaking, she licked her lips absentmindedly. A strange warmth stirred in her chest, and a faint blush spread across her cheeks as she pressed her legs together.
That scene had left a deep impression on Shinomiya Natsuha, as if something inside her had quietly been awakened.
Meanwhile, in the infirmary, Kazuma himself knew he wasn't actually in danger. He understood what was happening—his evolution was still ongoing, his body's cells continuing to change and reorganize, which caused these reactions. Although his mind felt hazy, there shouldn't be any real risk; otherwise, the communication card would have already intervened.
He simply hadn't expected the process to be so overwhelming. The heat continued to build, making his consciousness blur. Through the haze, he vaguely heard the girls talking around him.
"It was like this last night too… almost like he had taken some kind of stimulant."
"He looks like he's about to lose control. What should we do?"
"We just need to help him calm down somehow."
Soon after, Kazuma felt someone close beside him, voices soft and movements gentle as his awareness gradually drifted.
