Galian

Galian was the first boss, and founder, of the Luberian Thieves guild in MÄR Heaven. But a little while after he came across, saved the life of, named, and accepted Nanashi into the guild, he ended up making him the new leader by passing on the ÄRM called the Electric Eye. He also erased any memories Nanashi had of him before he abandoned the guild to become a Chess Piece, seeking more power.

Now, he's a knight-class Chess Piece, a traitor, and the target of Nanashi's revenge.
