This song is based off of hide and seek alone. The way the game works is by taking a stuffed doll with limbs, and replacing the insides of the doll with rice. Afterwards a red thread is used to sew the doll back together. Salt water is placed in a chosen hiding space, and the doll is placed in a water-filled bathtub. "First one to be it is (your own name)" is said three times, then you hide in your hiding place and count to ten. You then return to the doll and stab it, and say "Next one to be it is (doll's name)" three times. After that, you hide until you wish to stop the game, where you put some salt water in your mouth, go out to look for the doll. When the doll is found, spit out the salt water over it and say "I win." three times, then pour the remaining salt water over it, burn the doll and sprinkle salt in every corner of the house. People have said they have had strange experiences playing this game, such as the TV or radio turning on by itself, etc.

The song makes lots of references to the game such as a strange news broadcast playing on the TV.

Warning of Impostors (ニセモノ注意報)
Sung by: IA The second song in the series. This song is based on an urban legend of doppelgangers, where it is said that if you see your doppelganger, you will die within three days. In the lyrics, you can find Japanese traditional games related to shadows (kageokuri or kagefumi/shadow-stepping tag).

This story is about a girl who sees a news broadcast about doppelgangers, but thinks that it is a "stupid story" and ignores it. She then sees two people's doppelgangers, and those two people later die; the doppelgangers are theorized to be those of the protagonists of Hide and Seek of Isolation and Perfect Crime Love Letter. Afterwards, she sees her own doppelganger and dies. This song is related to Aimless Imitation Chair Stealing Game.

Perfect Crime Love Letter (完全犯罪ラブレター)
Sung by: IA The third song in the series. This song is based on the urban legend, Mearry-san. It tells about a boy who constantly receives messages from an unknown person called @mearry1713. Throughout the song, he keeps receiving these messages and having flashbacks to the past. At one point, he kills another boy, theorized to be the one in Hide and Seek of Isolation; at the end of the song, he is sent one final message, saying, "I'm right behind you".

Aimless Imitation Chair Stealing Game (猿マネ椅子盗りゲーム)
Sung by: IA The fourth song in the series. This song is about a girl who badly wanted an item called "The Monkey's Paw", which could grant three or five of its owner's wishes. The girl wants to become the 'same' as the girl from Warning of Impostors. There is a possibility that this girl is or becomes the doppelganger of the girl from the second song, because she is an "imitation" and wished to be the same as the other girl.
