Hayato Fuurinji

風林寺隼人, Invincible Superman, Jiji, Elder, Old Man, Garyu X
Mius grandfather and the undefeated elder of the Ryouzanpaku Dojo who is said to have beaten 500 Shaolin masters to near death. His kicks have speeds that are still a blur even when viewing a replay of it at 1/1000 of the normal speed. If necessary he is able to intimidate the other masters in order to maintain peace. Even using just 0.0002 of his power he can easily overwhelm both Kenichi and Miu at the same time and rip a tree in half.
