Gennai

 I have lived over 900 hundred years, you'd think I have forgotten many things during that time? You're right, but through meditation I can search my mind for those things I have forgotten. Like your names, I already forgot them but I can remember them again if I meditate. But it would spare some time if you'd introduce yourselves again. 

-Gennai to Leo, Mimi, Koga and Eve

Gennai is the Grandmaster of all Akagi's. He is a very old hermit. He traveled to north to live in isolation so he could spend the rest of his life meditating. He also wanted the younger Akagi Masters to learn to protect Mirenia and not be dependent of him.

He may seem like a fool, but he actually hides his intelligence by acting or talking like a fool. He pretends to have bad memory, but he uses that to reveal the frustrations of a person if there is any. He believes that patience and serenity in all situations is the key to right actions.

Gennai is very powerful with magic and he has mastered the use of Light and Ice elements. He has made an Oath to never kill anyone because he values life over everything else.
