I waited a long time for this story, It's a shame it's not a very happy story, with Add killing heroes back and forth, but it's still a good story... I mean, he still has Eve.
I want to tell you the sad truth (spoiler) Add has not killed any hero yet, Nighteye and No. 13 are held hostage and the one who killed Midnight was Eve with the dynamos of Add
although if he is going to kill more heroes, in addition to the super end of the volume, which has been said for 3 chapters (super spoiler), the next volume. Add. He is in a wheelchair and Eve takes care of him, the world will be DXD
