Kaoru is a master calligrapher with an AI assistant he calls Carla. Long pink hair and gentle golden brown eyes, he always seems to remain a cold stern mask to show the world, even if he looks fragile with soft features and porcelain skin. In the night he finds time to go to S, which is build in an abandon mine, the underground skateboarding competition he helped start as a teen. He goes by Cherry Blossom and he's quite popular there. He often butts head with Joe, another skateboarder.
