On the other hand I am not a big fan of issei but i must admit his tenacity,which be a zero to become a hero,as the brat perveritdo egoist of the first volumes at l current issei without losing its features as a character,a great achievement got ichie and also as issei was bred as normal human ,its vision of life spread to the supernatural beings or related by which they transmitted a vision of life more free and normal away from the battles,gives them peace of mind and security.
