Negai wo Kanaete Moraou to Akuma wo Shoukan Shita Kedo, Kawaikatta Node Kekkon Shimashita: Akuma no Niizuma

Theo Asper is a member of a mercenary guild, yet he is the weakest of the weak. His lack of strength forces him to constantly switch parties, and he never finds a place to call his own. Wanting to grow stronger, he decides to summon a devil who can grant his wish. He hopes the summoned being will change his fate, but he gets far more than he bargained for. The devil who appears before him is unexpectedly cute. Rather than merely fulfilling his request, she becomes his wife, and Theo's life takes a new and unpredictable direction. What follows is the story of an herbivore man and a carnivore devil, a slightly naughty (?) tale about two unlikely partners pursuing happiness together.
