YU-NO: A Girl Who Chants Love at the Bound of This World

Takuya Arima is a college-age student whose father, a historian, vanished some time ago. One summer he gets a strange package from that missing parent along with a letter hinting at the existence of parallel worlds. Inside the parcel is a device that actually lets Takuya move between alternate dimensions. At first he treats the whole thing like a prank or a weird academic experiment, but the device proves real and dangerous.
