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

Theo Asper is a registered member of the mercenary guild, yet he stands as the absolute weakest among his peers. Because of his lack of strength, he finds himself constantly shuffled from one adventuring party to another, never able to secure a permanent place or forge lasting bonds with his comrades. Exhausted by this endless cycle of rejection and desperate to finally grow stronger, Theo makes a drastic decision: he performs a forbidden ritual to summon a devil, hoping the powerful entity will grant his singular wish for true strength. However, the encounter takes an entirely unexpected turn. Instead of striking a terrifying bargain with a fearsome demon, Theo discovers that the summoned devil is remarkably cute. This revelation completely derails his original plan, leading the timid, gentle-natured mercenary to make a life-altering choice—he decides to marry her on the spot. What follows is a slightly risqué and heartwarming tale of an unlikely union between a meek herbivore of a man and a bold, carnivorous devil bride. Together, they embark on a unique journey toward happiness, proving that finding love can be far more rewarding than simply seeking power.
