Twenty year old Kira Ishikawa is having a rough go. She can't use a computer, her parents can't live together, and her gap year from school might be the rest of her life unless magically-assisted crime can finally pay tuition. Anything she touches also experiences her feelings tenfold, whether starvation, abdominal pain, or crippling self-doubt. (Thanks, Dad.)

But one last job for a city crime boss may solve her school woes. Unless, of course, a mysterious black box defying known laws of magic appears to muck it all up - a box no one knows anything about, even the friend whose blood it responds to: one who can suddenly play his hidden feelings straight for Kira upon touching it.

What could go wrong?
