Metaclim: メタクリム
A dinosaur-like Horror in stocks that possesses the corpse of Guillermo ギレルモ, a Makai Knight who was executed in Mendoza's arranged witch hunt. Metaclim serves Mendoza by posing as the captain of a squad the advisor sends out of Valiante to assassinate Germán and León, only to end up being slain by the latter.
