Idk If I will continue it your guys choice really...enjoy! It wasn't a normal genocide run like you have seen it before .The human was confused but didn't care that there were more new important monsters. It means more EXP and LV for them . Now they have to face a more difficult monster that is angered at them for killing his two sons and daughter. Who will win this battle to the death? Chara or Gaster?
