Arthur Gets reincarnated into the Earth of Overlord and then gets transmigrated but what's this? Instead of the New World he's in Tensura? 500 years back in the past! Thrust into the World of Tensura of the past, he will have to decide which route to take. The path of a World Conquerer? Or live a simple Carefree life with his NPCs? Note: The story Will loosely follow the OverLord Elements and Tensura's Power system to some extent. This Fanfic will be an AU meaning changes! yay!, but not much changes will be in the original plot. Characters may appear when they shouldn't but it's the effects of 'butterfly fluttering away' so relax and enjoy! Also Obviously I don't have any rights on Overlord Anime/LNs or Tensura/TTIGRAAS. OCs are ofcourse mine though.
