Sakura Haruka

He is a first-year student at Furin High School and member of Bofurin's Vaisravana Unit as well as the first year Grade Captain. Constantly judged by his physical appearance, Sakura adopts a delinquent persona that others have projected onto him and moves to Makochi to attend Furin High, an infamously rough school known for its strong guys and delinquents, to fight his way to the top.

Sakura is a teenager of average height and weight. His hair is naturally split in color - half black, half white - and he has heterochromia, with his right eye color blue and his left color yellow. He is commonly seen wearing the standard Furin High uniform consisting of a plain white t-shirt underneath his gakuran jacket, dark green pants, and a pair of black sneakers.

Sakura is reactive, determined, and perceptive. As a result of his unusual appearance, he is used to being judged and ostracized by others, which contributed to his aloof demeanor and delinquent persona. Sakura's standoffish behavior is shown to be a defense mechanism that he adopted in response to the discrimination he continuously faced in childhood due to his "unusual" appearance. He also shows to have strong and clear morals on who and why he fights. He has an aggressive manner of speaking, but when not brawling, he keeps to himself. He is much more comfortable fighting his way out of situations, as any other kind of positive interaction leaves him flustered. He is depicted as a "tsundere" throughout the series who has a hard time accepting any sort of affection.

Sakura becomes uncomfortable and flustered when people show him kindness or acceptance, and despite his tendency to get involved in affairs that result in helping others, he is not good at dealing with gratitude. Even with his social ineptitude, Sakura is extremely sensitive to romance when it involves those around him and often gets extremely embarrassed or flustered when he senses any form of romantic interaction or interprets something to be romantic. He is also terrified of forming bonds, and he lacks confidence in anything besides his fighting abilities as he thinks that his entire worth lays on them.

After learning that Bofurin uses its strength to protect the town and that delinquents are an important part of Makochi's community, Sakura starts to warm up to this idea and later finds himself viewing his fellow students as comrades rather than adversaries.
