Qualia the Purple

Through the uncanny purple eyes of Yukari, all people appear to her as robots. Her talent is both a blessing and a curse. She is able to assist the police in sizing up threats, since her “skill” allows her to evaluate humans’ quirks and physical capabilities like cataloging the parts of a machine–yet her strange sight has cost her the friendship of her peers. She does have one friend in her corner: Hatou “Gaku” Manabu, a girl at school who cares deeply for Yukari. When Yukari is recruited into a secret organization, the real trouble begins. Gaku is thrust into a realm of mystery, quantum experimentation, and alternate universes, with only her wits–and her love for Yukari–to guide her along the way.

Instead of the invincible warrior he mains, he’s in the body of Nacht Schatten, the alluring dragon princess he made as a joke!
