Kaji Ren

Furin High School is the central institution in the action-fighting anime Wind Breaker (2024), produced by CloverWorks. It is an all-boys school populated by delinquent students who, instead of causing chaos, use their strength to protect their town, Makochi, acting as local heroes known as Bofurin.

Sakura Haruka: A new male student who arrives at Furin to become the strongest.
He has half white, half black hair and heterochromia (one eye is a different color than the other). Initially, he is aggressive and solitary, but gradually learns to trust others and fight to protect them. He blushes easily at displays of affection, whether from himself or others.

Kyotaro Sugishita: Sakura's male classmate. Very quiet, intimidating, and extremely strong. He is fanatically loyal to Umemiya, the leader of Bofurin. He speaks little and tends to act more than he speaks.

Hayato Suo: Calm, kind, and always smiling. Although he seems relaxed, he is very skilled in combat and has great emotional intelligence. He often mediates conflicts. Sakura's best friend.

Akihiko Nirei: A nervous boy with glasses who takes notes on the fighters. He's not as strong as the others, but he's observant, strategic, and very loyal to his friends. Sakura's best friend.

Hajime Umemiya: Leader of Bofurin. Charismatic, kind, and extremely strong. He believes that strength should be used to protect the city and the weak, which is why he leads the students as defenders of the neighborhood.

Toma Hiragi: He is the captain of the Vaisravana Unit of the Bofurin Gang and a third-year student at Furin High School. He is one of the Four Heavenly Kings, Hajime Umemiya's right-hand man, and his best friend. He is an old friend of Kota Sako and the leader of Kaji Ren.

Kota Sako: He is a member of Shishitoren. He is a childhood friend of Toma Hiragi and Kaji Ren. After his defeat, he reconciled his friendship with Hiragi and Kaji.

Takeshi Enomoto and Yuto Kusumi: Both are second-year students at Furin High School and act as Kaji's direct support on his team. They have known Kaji for some time and are close to him, trusting him and understanding his difficulties.

He likes peaches and skinny jeans.
He hates pickled dishes.
He seems to like low-cut sneakers.
He dyed his hair blond himself.
Rumor has it that he was given his headphones as a gift, so he takes very good care of them.
Although she likes to listen to music, she doesn't sing.

He is always full of lollipops.
It seems he likes simple sweatshirts.
Apparently, she doesn't have that many clothes.
He seems to really enjoy being in noisy places, but he doesn't get noisy or excited.

Despite his seemingly calm and indifferent demeanor, Kaji possesses a fierce and relentless fighting style. He is a fast and powerful fighter who gives his opponent no respite. He delivers rapid blows with the aim of subduing his adversary.
Kaji fights with an energy that borders on frenzy when enraged; his movements are so swift that he can perform aerial acrobatics, ground maneuvers, punches, takedowns, and kicks. Kaji enjoys a great reputation for his strength and skill.

Kaji is the captain of Bofurin's second-year class. He is also one of Bofurin's strongest fighters. He is considered the strongest second-year veteran and one of the strongest fighters.

Kaji is a boy of average height with platinum blonde bowl haircuts, blue eyes, and a muscular build. He wears the Furin High School uniform: a green gakuran jacket over a gray hoodie, black jeans, and black low-top sneakers. He wears headphones and often sucks on a lollipop.

Ren Kaji's personality is calm, reserved, and very controlled. He speaks little and prefers to observe before acting, almost always maintaining a relaxed and distant demeanor. Although he seems indifferent, he is actually a perceptive and reliable person, capable of calmly assessing situations even in the midst of conflict. He doesn't seek fights or attention, but when he decides to intervene, he demonstrates great skill and determination, acting more out of responsibility and a desire to protect others than out of personal pride.
