Rin continues her quest across Japan to avenge the murder of her parents, joined by Manji-her seemingly immortal protector. The eccentric, bloodthirsty Ittö-ryü sword school tries to carve a path to Edo Castle, led by the hated Anotsu as they obliterate all rival schools along the way. The deadly Mugai-ryü has formed, though-with the sole purpose of destroying Anotsu's clan! Collects volumes 4, 5, and 6.
