In Another World with My Smartphone - S01

Touya Mochizuki is getting used to his new life in another world. With his trusty smartphone in hand, the teenager takes on small quests whenever he feels like it, spending his time with his new fiancées: Yumina Urnea Belfast, Yae Kokonoe, and the twin sisters Linse and Elze Shileska. But even in this relaxed setting, Touya is just starting to grasp the responsibilities that come with these engagements. On top of his romantic troubles, the elder fairy Lean wants to find the remaining pieces of Babylon, the floating island that the mysterious Professor Regina Babylon created five thousand years ago. Touya reluctantly agrees to help and searches for the teleportation circles that lead to the islands. But strange monsters have appeared, possibly powerful enough to destroy the world. To protect the second life he was given, Touya must turn ancient technologies into weapons to fight these monsters, all while juggling his overwhelming number of relationships.
