If It's for My Daughter, I'd Even Defeat a Demon Lord

Original title: うちの娘の為ならば、俺はもしかしたら魔王も倒せるかもしれない。

Dale is a cool, composed, and highly skilled adventurer who's made quite a name for himself despite his youth. One day on a job deep in the forest, he comes across a little devil girl who's almost wasted away. Unable to just leave her there to die, Dale takes her home and becomes her adoptive father. Devil or not, Latina is beyond adorable, and the adventurer soon finds himself head over heels with being a parent. But why was she out in the forest to begin with, and why does she carry the mark of a criminal?
