A Womb Realm mandala owned by Hazama Shigeharu which contains hair from more than 500 members of the Araki Clan, who were slaughtered by Oda Nobunaga after Araki Murashige escaped from Itami-Arioka Castle.
A monk of Mt. Hiei sealed the onryou of the Araki Clan into this mandala so they would no longer haunt Araki Murashige in exchange for his consent to becoming a human pillar of Osaka Castle after his death.
The Ikkou Sect desperately wanted this mandala in order to make it a cannon-like weapon.
