Naraka Hitsugi

Naraka Hitsugi (Hell Coffin, 地 獄 棺) is a Noble Phantasm of Seito Kurogane, acting as his strongest Defensive ability, able to cloak the user in Hellfire and act as a shield. Unlike his other Defensive Noble Phantasm, Entenka this Noble Phantasm can be cast on other people to either defend them too or act as a form of Torture, slowly shrinking the size of the coffin until they're burned.
