Mix of Second Life Ranker (novel+webtoon) and Reincarnator (novel).
Choosen among the gods (actually high rankers in the tower, but we know them as gods, aka Zeus, Odin, Sun Wukong etc) to be send back in time to redo everything and prevent destruction of the tower from Outer Gods. Hogs everything for himself and bad at teamwork like in Second Life Ranker.
You may feel your favorite manga should be gathered together into distinct categories for your own reference and, now, you can do this with a LIST. After you've created your list or lists, you can proudly recommend them to other manga fans to showcase and share your taste in manga.
