Kousuke Misaki

Kousuke is a strikingly handsome young man, often described as a "pretty boy."

His features are so fine that he can be mistaken for a girl at first glance, making him a heartthrob at school.

He is one-quarter British, which likely contributes to his distinctive good looks.

On the surface, Kousuke is incredibly calm and gentle, with an approachable and kind nature.

He is a fantastic listener, a quality that has earned him great respect and admiration from his peers.

However, beneath this placid exterior lies a shockingly fierce side, which erupts when he feels his loved ones are threatened.

When he mistakenly believed Carol was in danger, he unleashed a murderous aura so intense that even Tomo and Junichiro together couldn't hold him back.

As a child, Kousuke was introverted and frequently bullied for his delicate appearance.

His journey into martial arts began with a single, powerful motivation: to become strong enough to protect his cousin, Carol Olston.

This childhood promise to himself fueled his dedication to karate and shaped the person he is today.

Kousuke serves as the capable captain of the Boys' Karate Club.

His true combat potential is revealed when he's enraged, becoming so formidable that he's difficult to restrain.

Feeling ashamed of his lack of control during an outburst, he joins the Aizawa Dojo to pursue more rigorous and disciplined training.

Carol Olston

Carol is his cousin, who has held a long-standing crush on him.

He was aware of her affection but suppressed his own romantic feelings due to years of internal conflict and anxiety.

Publicly, he maintained the facade that she was just a "precious but handful of a cute little sister."

After a series of chaotic events, he finally confesses his love, and they become a happy and devoted couple.

Tomo Aizawa

He is on very good terms with Tomo, who is also a member of the Boys' Karate Club.

He proudly declares himself a "fan" of Tomo, holding a deep and sincere admiration for her exceptional karate skills.

Junichiro Kubota

Junichiro is wary of Kousuke's close friendship with Tomo.

He also comically ends up as the primary victim of Carol's rampage after she misunderstands Kousuke's feelings for Tomo.

Misuzu Gundou

Misuzu's scheme to get even with a rampaging Carol ironically creates the perfect storm for a resolution.

Her meddling inadvertently pushes Kousuke to finally be honest about his feelings for Carol.

Due to his handsome looks and gentle personality, Kousuke is immensely popular with the female students at his school.

He is of one-quarter British descent.

(Regarding Tomo's skills) "I'm her fan."

(His public stance on Carol) She is a "precious but handful of a cute little sister."

Early Life and Motivation

In his childhood, Kousuke's introverted nature and pretty-boy looks made him an easy target for bullies.

He resolved to become stronger, dedicating himself to karate with the singular goal of being able to protect his cousin, Carol.

A Hidden Ferocity Unleashed

One day, Kousuke mistakenly believed that Carol had been assaulted by delinquents.

This misunderstanding triggered a terrifying transformation, as he flew into a rage with a demonic expression and an overwhelming killing intent.

Deeply ashamed of this violent outburst, he sought to master his power and emotions by joining the Aizawa Dojo for more intense training.

A Cascade of Misunderstandings

Unfortunately, Carol misinterpreted his deep admiration for Tomo Aizawa's fighting skills as a romantic crush.

This led a jealous Carol to go on a chaotic rampage, with Junichiro Kubota somehow bearing the brunt of the consequences.

A Fated Confession

Seeking payback against Carol for her antics, Misuzu Gundou hatched a plan that ended up entangling everyone involved.

In the midst of the chaos stirred up by Misuzu, Kousuke was finally pushed to confess his true, long-suppressed feelings to Carol.

His confession was reciprocated, and the two happily began their relationship as a mutually adoring couple.
