Kaede was adopted
at a young age by a legendary swordsman named Gaisai, who also adopted and
As he aged, Kaede became an avid swordsman and powerful warrior, surprising
even himself. One day, when he was twelve, he and Yuki returned from an errand
to discover their master slain and Moriya standing over his corpse. Enraged,
Kaede physically attacked him for the (presumed) killing of their master.
Moriya withstood the attack and left in silence.
Kaede and Yuki depart their foster home to avenge the death of their master
and confront the killer. Five years on their quest, he still searches for
Moriya. He eventually discovers that the real killer of his master was one of
the four guardians of hell, Shinnosuke
Kagami. He engages him, but the guardian's superior skill quickly
overpowers him. However, it is revealed that Kaede possesses the power of the
legendary dragon Seiryu, one of the Four Sacred Beasts of Chinese
mythology. He can transform with the beast's power, changing various physical
aspects and giving him additional power. With his transformation into "awakened
Kaede" , he defeats Kagami.
After honing his
skills and learning to control the power of the Seiryū to a greater
extent, Kaede and Yuki set off for Okina
in order to find more information. When they arrive, they discover that the
“Sealing Rite” needs to be performed, for a great evil threatens the
world. This rite is to be performed by a special maiden, but a warrior named
the "Messenger From Afar" seeks to assassinate her and prevent her
from performing it. Kaede sets out to protect the maiden and to allow her to
accomplish her mission. The name "Kaede" means "maple".
