The Shape-Shifting Witch's Kiss Volume 1

Tohru has a superpower—he manages to be invisible without any magic at all! In fact, the only one who truly sees him is his childhood friend, Tsumugi, leading Tohru to have the crush to end all crushes on her. But when Tohru's "ability" leads him to accidentally discover a witch and strip her of her powers, he thinks he's screwed...until she offers to help him hook up with Tsumugi. But this witch's powers are revived only with a kiss? One thing's for sure—Tohru won't be invisible for long!
