Long ago, a Spider {{Yokai}} killed a lot of people; but a brave monk challenged her.

In modern day; a young used bookseller (Suzuri) and his landlord's granddaughter (Mizuki) crack a [[SealedEvilInACan sealed book]] that had an offspring of that spider. The spider takes the form of young innocent child; and they take care of her.

A heartwarming tale. [[spoiler: Or not.]]
