Garm

Undead Magic Beast - Garm are beasts that dwell at the Library of Demise in the farthest realm, and typically have the power to slaughter three mages in Magus Mode with ease. When fully grown they can well surpass demons, which are known as the most powerful. As high-ranking magic beasts who can bring about enormous damage if given the chance to appear in this world, they have tenacious strength to rip humans like paper and though fur able to withstand all kinds of weaponry, but what makes these beasts truly frightful is that they will always revive soon after being killed.
