Lived for the sword, died for the sword. There’s no regret in in his lifetime-only one thing, but only admiration remained. One day Souma recovers his memory from the previous life, but also on the same day he was brand as incompetent person. Denied by what he long for. However for Souma, it has nothing to do with him. Ancient ruins, underground labyrinths, demon’s territory, forest of witch.
