The Three Legendary Bakkōtō, created by the inventor Shūhen Kōhai using his own intelligence and secrets obtained from the Kasumiōji Clan and with use of Heisekai's superior craft, are Bakkōtō of unrivaled power that were spread throughout the spiritual realms by one of Shūhen’s three apprentices upon their completion, in order to stop her master from using them to disrupt the peace, or for personal gain. Their shape, name and location is currently unknown.
