Commonly called "Water Dragon Makidai", since his element is water. His main weapon is a spear, with which he can form giant water sharks. He can also walk on water without sinking. Makidai is always annoyed by Hiro and the other XILE members and he often acts as though he doesn’t care for them, but in reality he values their friendship. He is also the one who finds out about the majinki’s headquarters in Roppongi.
