I think I have it.

Tall and muscular, having both a religious faith and beliefs of his own (or maybe in someone else), being feared as a demon, and having enough will to fight back in desperate situations... a primary spear wielder (or is it a naginata?) with access to other weapons...

That goddamn hint about Lancelot (Knight of Honor)...

Is it Oniwakamaru, the real Musashibou Benkei?
