In the anime Wind Breaker, there is a character named Ren Kaji (梶蓮), who fits the description of a repeater and plays a leadership role—he is the captain of the second-year team, the Bofurin Squad, at Furin High School.

Voiced by: Nobuhiko Okamoto (Kevin D. Thelwell in the English version). Appearance and Habits Often appears with headphones listening to music. Spends a lot of time on his phone. Height: about 170 cm, age: 16-17 years old. Outwardly, gives the impression of a detached and indifferent student. Personality At first glance: calm, sullen, a little harsh in expressions. In reality: sensitive to small details – easily angered. Hidden side: caring and sympathetic, willing to help his friends despite his cold exterior. Outspoken, open about his opinions, yet able to be considerate of others. Role in the plot: As captain of the second-year team, he is responsible for organization and discipline within the Vaishravan squad. Like the other members of Bofurin, he participates in protecting the city and maintaining order. He combines contradictory traits: on the one hand, aloofness and a tendency to keep to himself, on the other, responsibility for the team and a willingness to act for the common good.
