Slaying Demon: Ōkami

Interfectum Malus: Ōkami is a form of a nodachi. According to Continuum Shift, it is made of a metal that negates Ars Magus in a certain distance, explaining why Arakune can be killed by it in Calamity Trigger rather than reform. During the Teach Me, Miss Litchi Reloaded episode, Ragna taunts Hakumen, sayin that "it has yet to actually display its power". Ōkami means "Howling God" or "wolf" depending on the reading (although judging by the appearance of Hakumen's crest, the latter meaning is more likely). It can also mean "Great God" and is a frequent honorific used for Shintō gods. Interfectum Malus is a Latin phrase probably intended to mean "Evil Destroyed" or "Evil's Destruction", but its Japanese name can also mean "Evil Cutter".
