its KINDA ripping them off caus its like gluttony hoped to another comic..just saying

actually its not ripping them off, its just using the same concept. 7 deadly sins isnt FMA's trademark, and I have the 7 heavenly virtures as the badguys enemies.

Is this series knocking off FMA cause they have 7 sins too, this actually resembles the gluttony from Fullmetal alchemist only more realistic.
