Somehow, after drinking a "Potion to Become a Girl," he ends up experiencing a "Zap!" moment with Koitaro! What will Kawaru do? Is he doomed to fall? Or is he definitely doomed to fall? Wait—was Kawaru originally supposed to be a girl? Did the God of Birth mess up his gender, and then the God of Love followed suit in a chain of mistakes? Damn you, Friday Roadshow! From 100 Girlfriends to… 101 Girlfriends! Not 100, but 101 Kanokano! What in the world is going to happen next⁉
