This spell is a spell that is used to free a spirit from demonic binding. While not much is known, it's hinted that the spell itself was of Japanese origin.
To perform the spell, the spell required a blessed katana. During an encounter with a spirit which is bound, the caster must recite a spell before slashing and stabbing the spirit in the chest, where the heart is placed. After being stabbed, pure white flames will appear around the spirit and burn so bright burning the spirit. After that, the spell will be released from all bindings and able to move on. But any demonic essence remaining will be sent back to Hell.
