The Way that the series is going on it is becoming like Dragon Ball Z because everyone here has insane power levels, and by how strong Issei has to become he must go Super Saiyan Level 4 or higher in this story because these people are insane just look at Vali's grandfather because he has a ability that nulllifies Sacred Gears which means a quick death for every user of a Sacred Gear how in the hell can you fight someone like that.
