異世界から来た魔族、拾いました。 うっかりもらった莫大な魔力で、ダンジョンのある暮らしを満喫します。

In a world wearied by the grind of societal expectations, Toudou Keita, a former corporate drone, encounters an ethereal duo: a fluffy, white dog-like creature and a pint-sized demon child, both hailing from another realm.

After being exploited and ultimately discarded by a ruthless corporation, Toudou Keita stumbles upon the spectral forms of a young girl and a dog while en route to a convenience store. To his astonishment, they are beings from another world, dispatched to explore dungeons in this realm.

Due to an inadvertent mistake by the young demon girl, Keita finds himself endowed with an unprecedented level of magical prowess. Consequently, he agrees to assist them in their dungeon exploration endeavors. As fate would have it, he also offers them shelter, initiating a cohabitation scenario with the fluffy canine and the vivacious young demon girl.

Thus begins a new chapter in Keita’s lackluster life. His encounter with these otherworldly beings and his subsequent adventures in dungeon exploration mark a turning point, injecting newfound vigor and purpose into his previously monotonous existence.
