A girl named Mari is in an abusive relationship with her former friend (who happens to be identical to her), Juri. Juri contacted The Hotline to Hell because she and Mari had a close relationship that was ruined in her eyes when Mari briefly considered having an upperclassman as her tennis double instead of Juri. Juri has been forcing Mari to do exactly what she says, otherwise she’ll pull the string. Ichimoku Ren becomes involved when trying to get more background on Mari and figuring out why Juri hasn’t pulled the string yet. Juri gives Mari an album of pictures of them together. After going to get Juri’s lunch, Mari runs into Ren and hugs him when he comforts her. Juri, having followed Mari in order to tell her she’s decided to forgive her, is angry that Mari could be close to anyone else and runs off to pull the string. Mari tells her they’ll always be together, but at that moment Juri is hit by a car and fatally injured. Mari pulls the string on the doll so that they’ll be together in Hell and, shortly after she’s taken, Juri arrives in Hell. Somehow, Mari has taken the album with her.
