Akari isn't wild about moving into an eerie old house...until she meets Non-chan, a cursed doll! And what's this? Non-chan says she wants them to be together forever!? (And maybe something else about "haunting" and "eternal regret"? That's probably not important.) Akari, bewildered as she is, accepts Non-chan's proposal. Now Non-chan seems confused too, but no matter. Akari just knows she's found her new BFF!
