DB: Reincarnation Game

(A Self Insert-Cooler story heavily inspired by "That Time I Got Reincarnated as Yamcha" and "Budokai Tenkaichi 3"'s Sim Dragon.) I expected many things in life. Not a single one of them was waking up in Cooler's body, fighting against a Cell-wannabe that wanted to eat me, or falling in love with my reincarnated partner. But, hey, who said life was simple?
