One day, a boy named Takahiko Amano (who's very much an indoors type) has an sudden and unfortunate accident. Ever since then, his spirit has called out, "Release me! From this body, from this lonely isolated life, and from this miserable fate!" Then, with a crash, a "spirit separationist" arrives and puts Takahiro in a situation he never could have imagined!
