Shiba's Shadow

After Lady Amaterasu took and scattered the Ancestral Swords in Tengoku, the Phoenix Clan tried in vain to copy the sword Ofushikai and name it as Shiba's Shadow. The sword has the same qualities of Ofushikai but there is this one deadly flaw instilled on it: instead of anchoring the soul of Shiba, it traps the souls of all who tried to wield it. Until now, the Phoenix Clan is trying to unmake the sword and free the souls trapped in it. Shiba's Shadow is currently being studied in Gisei Toshi.
