Seiken the Mage (Crimsfon)

Seiken the Mage was the appointed guardian of Buck. He aided him in his early fights like the ones against the Flame Lord and Xonious. Seiken would later tragically die after giving up his soul to defeat Trenon, the Trio Master with a huge amount of magic.

Not much is known about Seiken Crimsfon.

When Pureas Cosray received supreme knowledge of the Multiversse, he revealed the last names of many. Raidan and Seiken were just two. It was revealed that they are both brothers, as they have the last name of Crimsfon. Raidan was an Overseer Captain that fought alongside Buck and Seiken in the Epic Katana Saga. He mysteriously vanished. Seiken was appointed by Buck's parents to guard him until his tragic demise. Buck quickly became stronger than Seiken. When he died, he became the second God of Magic, a choice by Paun and the Immortal Order.

Seiken's soul used to reside in the Undead Dimension, since he destroyed his soul, but recently, it was shown that Seiken is no longer there. Currently, he roams the dangerous Universes as a spectral version of himself, using magic to help those in need.
