Takane "Ene" Enomoto (as a human) is very bored on this average day. She turns on the radio when a country's president, in tears, announces that the world is ending today. She had a half finished game with no save and a textbook. She was scared and to stop her body from trembling she put her headphones on. Listening to an unknown song, by an unknown artist, a voice from her headphones suddenly asks her if she wants to survive. She claims the voice is her own. It tells her to go 20 seconds ahead and cross the hill; for better or worse she will find out what her voice meant. On her way she crosses a crowded intersection and mentions a sobbing girl. Her voice tells her that 12 minutes are left. She says if everything is going to vanish, she has no other choice but to listen to the voice from the headphones. Many minutes pass as she runs, having only one minute left. Enomoto claims she can no longer hear the voice because the hill that she is supposed to cross is right in front of her. When she gets to her destination scientists congratulate her. She finds out her town was an experiment that is no longer needed. One of scientist calmly tosses a bomb. She is told she was living her whole entire life in a box. She then looks at her town, which is now a burnt wreckage. From her headphones she hears a faint "Sorry" and the viewers see an outline of Ene.
The song was featured as the opening theme of episode 6 of Mekakucity Actors sung by LiSA.
This song is one of the tracks in the Kagerou Project.
Fans think Ene was trying to save her past self from dying in bombing.
Enomoto mentions a sobbing girl. That girl could be Hiyori.
Many think Kenjirou (Ayano's father) is one of those scientist that blew up Enomoto's town.
Enomoto somehow lost her body in an experiment. When meeting Shintaro in the first chapter of the manga she has no memory since she says she really doesn't know. She could have lost her memory when escaping to the cyber world. It is however learned that Enomoto had been keeping her past as a secret from Shintaro.
