At a young age,
Moriya was accepted to train under
a legendary instructor, Gaisei. He
trained alongside Kaede and Yuki,
and eventually exceeded
the skill of his master. Even so, Moriya stayed with him because he (and the other children
he had adopted) were more like family. For
many years, they lived happily together while learning bushido.
But a day came, when he was seventeen,
that he found himself standing over the dead body of the man he respected
more than any other.
Kaede sees Moriya standing over Gaisei, and assumes he is the one that killed
Moriya found his master dead, and the killer was nowhere to be found.. With
this, he sets out on the run. Not only does he wish to avoid the confrontation
from Kaede, but he also seeks the man named Shinnosuke
Kagami (who was the real killer) in order clear his name. However, after
over five years of searching, Moriya has yet to find Kagami, who is defeated
by Kaede instead.
After failing to take
revenge upon Kagami, Moriya recluses himself to the wilderness to improve his
skills and techniques. During this time, he finds within himself an urge to
"return" to the portal known as "Hell's Gate". Ceasing
his training, he travels in order to seek the truth.
