Tsukimino Karma wa Akumade Boku no Pet Nanoni

Fudou Ryou is a loner because his face looks far too intimidating. One day, he is about to be hit by a truck when Tsukimino-san saves him. Wanting to thank her, Ryou-kun chases after Tsukimino-san, but ends up stumbling into the middle of a confession scene, where he is asked, Would you love me even if I were a demon? Tsukimino-san casts a spell of forgetfulness, but for some reason Ryou-kun seems to have a constitution that repels magic, and the spell bounces right off him. Panicking, she then casts a subjugation spell to make him her pet, but that too is repelled. Just as Tsukimino-san seems about to be won over by Ryou-kuns gift and words, the earlier pet-conversion spell comes falling down from above And so, unbelievably, Tsukimino Karma-san ends up becoming the pet of the human Ryou-kun.
