Shadow Knight

He is a C-rank monster belonging to the Demon Lord's Army. Thanks to his unique ability, he can nullify all magical attacks. Assigned to the mission of annihilating the strongest species, he targeted the spirit race and took Sora hostage in an attempt to force the removal of the barrier protecting the Forest of Confusion. However, in a battle with Rein Shroud and his group, who understood the situation, he was defeated by an attack from Kanade, empowered by Rein Shroud's "Boost."
