He's the final boss that Takeshi's party fought. Then they just bring him back. He is trying to fit into a mortal life now.
In my book, I wrote about him "an ancient god stands before you. His red eye glows dangerously in the darkness. he was once a beloved and respected god. Under his watchful eyes, the land flourished into paradise, the rivers ran clear, the skies sang with birdsong and the people only know peace. But kindness only feeds greed, and greed invites betrayal.slowly but surely, the paradise crumbled.... and in the end, so did he.
He should have been vanished. But he did not.
Now, he wanders the desolate remains if what was once his home - a haunted monument of dusted ruins and wind-blown silence. Time no longer touches him. His purpose lost, his mind fractured, he silently wait in this place. For what? He doesnt remember.but with a broken blade in hand, he is ready to strike down any foolish dare to step into his domain.

And now....you are standing a the threshold.will you run from him? Stand against him? Or will you be the one to free him?"
