Manga's pretty bland and very average. Demon Lord/ super OP being decides to reincarnate far into the future to start a new life with a different goal. It's similar to Rettougan no Tensei Majutsushi (The reincarnation magician of the inferior eyes) just slightly better. Shikkakumon No Saikyou Kenja (The Strongest Sage with the Weakest Crest) and Maou Gakuin no Futekigousha (The Misfit of Demon King Academy) did a way better job. I haven't read all yet but I somewhat know the general direction, being all generic and stereotypical and whatnot. Art is pretty meh I suppose with fan service here and there. One good thing, inmy opinion, is that it isn't as rushed compared to Shikkakumon and Maou Gakuin.

It's a decent read if you just want to read reincarnation-fantasy trope works; something to pass time by.
