Saicho (最澄, Saichō) is a member of Team Kuu, as well as it's second in command.
Saicho has a frail, and somewhat feminine look to himself, and has been mistaken for a girl at times in the series. His black hair is somewhat long, and hangs over the right side of his face. He wears a standard martial arts gi with paper folded around his torso.
He briefly lent his gi to Fuko to cover herself after Fujimaru strips most of her clothes bit by bit in their battle that renders her in a strapless ripped blue bra and panties with black linings which he formally apologizes to her for Fujimaru's awful behavior while treating her injured arm using his paper as bandages. The paper bandages on his torso is revealed to cover his chest wound after he was previously stabbed by one of the corrupted Ku students which makes him limit to fight.
He is a good natured, respectful, and friendly teenager. He is extremely devoted to Team Kuu, as his primary motivation for fighting is to prove that his team is not a low level group of thugs and assassins, but fighters who seek pure strength for the sake of strength. Despite being such a powerful fighter at his age, Saicho dislikes causing unnecessary harm to his enemies in battle and seeks to avoid pointless bloodshed. He is good friends with Kukai's daughter Misora (Kukai even suggested that the two get married).
