Ren Kaji 3 (Wind Breaker)

Kaji is a boy of average height (171 cm), with platinum blonde hair, dark gray 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.

Kaji is usually calm and lets his vice-captains speak for him. He gets angry easily, especially after finishing a lollipop, and reveals his short temper. However, Kaji strives to be a reliable senior captain and acknowledges his weaknesses, readily relying on the support of his vice-captains.

Kaji can be very reactive, especially when he's insulted or upset. As a result, he lashes out and enters a state of fury that allows him to fight whoever antagonizes him. Because of this, Kaji grew up with a lot of self-loathing and often distanced himself from others. It wasn't until Hiragi gave him his headphones that he learned to block out other people's negativity. He also uses his lollipops to avoid verbally lashing out.

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. It has a simple, white phone case (bought at a 100 yen store, similar to a dollar store). He prefers a wallet. When he is thirsty, he will always go to look for water. 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.

Furin High School is not just any high school; they are responsible for protecting the city from gangs that dare to steal or commit any crime. Kaji's vice-captains are Yuto and Takeshi Kaji is one of the strongest second-year students
