It is such a shame now that Issei's Sacred Gear is useless now because the enemy that he is fightning against nullifies Sacred Gears, and that to me is unnatural because Devils shouldn't have that ability at all because the power has to come from some sort of Sacred Gear because I want to know the source of this ability because it makes this guy difficult to kill because if he didn't have this ability he can be take out but now how in the hell can Issei destory him.
