Soul Removal: Mutual Death Seal

The Soul Removal: Mutual Death Seal is a complex fūinjutsu developed by Anjin's Mentor from the Six Tomoe Sealing Style. Being a kinjutsu, it seals away the target's soul while killing the user. For best application, it is used on the forehead of the target. Anjin's mentor proved it to be one of the ways to truly kill a Jashinist, sacrificing himself to save the remainder of Team Hasegawa, who also know the technique as a last resort.
