Toshi to Mahou wa Kiss Shidai

Tooru 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 Tooru to have the crush to end all crushes on her. But when Tooru'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—Tooru won't be invisible for long!
