Kaoru Sakurayashiki

Kaoru is a quiet intellectual, renowned even outside of "S" as a renowned and successful calligrapher in the field of artificial intelligence. He has been shown to treat clients and strangers with polite respect, but is often caustic toward those closest to him, most notably his fellow "S" member and childhood friend, Kojiro Nanjo. Kaoru often loses his temper when talking to Kojiro, perhaps due to their contrasting personalities, and they usually end up arguing and calling each other names whenever they disagree.

However, despite his personality, he genuinely trusts and cares for those he considers his friends. He also knows he can rely on his friends when he needs it, and he repeatedly comes to Kojiro's restaurant to discuss his problems, once even escaping from the hospital to do so.

Kaoru is also particularly competitive in skateboarding. Kaoru dislikes being compared to his "real" self as an "S" skateboarder. This shows that he has a certain professionalism and is reluctant to openly acknowledge his other side to anyone, perhaps due to his fame both within "S" and in the real world.

Kaoru is a man of average height and build, beloved by "S" viewers for his handsome looks. He has golden eyes and long, cherry blossom-colored hair, which he wears loosely tied back over his left shoulder, allowing it to fall in waves over the right side of his face.

Kaoru Sakurayashiki, also known in "S" as Cherry Blossom, is a skilled skater and member of "S", he uses his AI board to skate with calculation and intelligence.
