Kazeno

Kazeno is a male student in his third year of the high school division, assigned to Class 3-B.

He is a member of the rugby club, where his physical strength and training habits stand out.

During the school sports festival, he serves as the leader of the Red Team cheering squad.

Even after the sports festival ends, Yuu Ishigami continues to call him “captain,” a nickname that sticks to him beyond the event itself.

Kazeno is on good terms with his classmate Tsubame Koyasu, who is in the same year.

Around the time of the cultural festival, Ishigami suspects that Kazeno might be dating Tsubame due to their closeness, but this turns out to be a misunderstanding.

In reality, Kazeno was dating Kobachi Osaragi during that period.

However, they break up over the winter vacation because, as he puts it, their “vibes didn’t match,” indicating a mismatch in personality or sense of humor.

The breakup leaves Kazeno heartbroken, and this emotional blow becomes the trigger for him to dive deep into idol fandom.

His turn toward idols reflects both a coping mechanism and a new passion that contrasts with his athletic image.

Kazeno is earnest, energetic, and very straightforward, especially about physical training and sports.

He tends to express himself directly, even when it comes to sensitive topics like his breakup with Kobachi Osaragi.

His sense of “matching vibes” suggests he values compatibility in mood, energy, and interests in relationships.

At the same time, his ability to move on by throwing himself into a new hobby like idol fandom shows resilience and adaptability.

As an idol fan, Kazeno channels his intensity into following and supporting his favorite idols.

This new obsession adds a quirky, otaku-like side to his otherwise “jock” persona.

Yuu Ishigami

Kazeno has a friendly, if slightly comedic, dynamic with Yuu Ishigami.

Ishigami continues to call him “captain” after the sports festival, implying a mix of respect and teasing.

Kazeno encourages Ishigami to do muscle training, acting like a self-appointed fitness coach.

Through this, he tries to help Ishigami improve his physique and confidence, showing a supportive side beneath his brashness.

Tsubame Koyasu

Kazeno is close with Tsubame Koyasu, and they interact comfortably as classmates in the same year.

Their closeness leads Ishigami to mistakenly suspect that they might be dating around the time of the cultural festival.

Despite the misunderstanding, there is no romantic relationship between Kazeno and Tsubame.

Their connection instead highlights Kazeno as someone who can interact easily and naturally with others.

Kobachi Osaragi

Kobachi Osaragi is the girl Kazeno actually dates during the period when others think he is involved with Tsubame.

Their relationship does not last, and they break up over the winter vacation.

Kazeno explains that they separated because their “vibes didn’t match,” suggesting a mismatch in personality and rhythm.

The breakup leaves him wounded enough that it pushes him toward idol fandom as an emotional outlet.

Athleticism and Rugby

As a member of the rugby club, Kazeno has strong physical abilities and endurance.

His rugby background underpins his leadership during the sports festival and his emphasis on disciplined training.

Cheering Squad Leadership

Kazeno serves as the captain of the Red Team cheering squad during the sports festival.

In this role, he leads and motivates others, showing charisma, organizational skills, and the ability to energize a team.

His performance as cheering squad leader leaves such an impression that Ishigami keeps calling him “captain” long after.

This suggests that, despite being a one-time role, his leadership leaves a lasting mark on those around him.

Muscle Training Expertise

Kazeno has a strong fixation on muscles and physical conditioning.

He not only trains himself but also actively recommends muscle training to others, especially Ishigami.

In one instance, he even provides strength training guidance to Erika Kose, who is technically on the opposing side during the sports festival.

This shows that his passion for proper training can override team boundaries—if someone wants to get stronger, he will help.

His detailed interest in muscle development and training methods gives him an almost “trainer-like” presence among his peers.

This expertise, combined with his straightforward personality, makes him the go-to person for anyone wanting to bulk up or get fit.
