Yukinari's got girl problems - the poor guy is literally allergic to them. He can't even be in the same room as a girl without getting a rash. It's enough to put any red-blooded male in an awful mood. Here's the good news: things start looking up for Yukinari when he accidentally plays peek-a-boo with the naked girl-next-door. She freaks out and boots him in the face, magically transporting our hero to the coolest place ever - Seiren, a mystical land populated mostly by girls. As soon as he gets there, he meets Miharu, a super-bouncy, carefree cutie who can touch Yukinari without causing a rash! She becomes his roomie on Earth and - well, then it's all bathtubs, swimming pools, hot springs, and you're not even reading this anymore are you?
