Kisarazu Atsushi was accidentally recruited by Mizuki due to mistaken identity. Mizuki was really eyeing on Atsushi's twin brother, Ryou. Because of this confusion, Mizuki ordered him to cut his hair and put a ribbon around his head so that they won't be confused anymore. Kisarazu plays doubles with Yanagisawa and is also a very talented tennis player. He used his feint technique, wherein he acts as if he is going to miss a ball but in fact he can spin in the air and thus enabling him to hit it back.
