This episode revolves around three people, the first of which is Saki, a pianist. She is determined to make it into a music university, but she just can't make it. Then, Poom Poom gives her a balloon. After she let go of it, she killed herself. Quite a few people are now getting strange phone calls urgeing them to 'Come play with us.' Yoshiki, the one making the calls, gets taken in by Boogiepop Phantom and dissapears.

This episode revolves around Poom Poom, Manaka, and Paisely Park. More and more people are getting red balloons, making Nagi go to the park to see what's causing it. There are children versions there of everyone that had recieved a balloon. However, Boogiepop (not the phantom) arrives on the scene and causes Manaka to fall from the Ferris Wheel. All the lights in the park go out, and Manaka appears to have aged quite a bit. Apparantly, her powers made her age, and now that she used them like crazy, she aged greatly. All the phantom children dissapear, along with Poom Poom, leaving Manaka with Boogiepop.

This episode revolves around Manaka. It explains about her past, her mother, her grandmother, and her ability. After the flashbacks are done, Manaka starts to run from Boogiepop when Boogiepop Phantom interveins and tries to kill her. Boogipop frees her, stating that she hasn't enough power to cause a threat to this world, and Manaka runs off to the house of mirrors. Boogiepop finally meets Boogiepop Phantom. Manaka tells herself that she will not die; rather, she will become light. And so she does. A great light composed of the golden butterfiles engulfs the land, causing time to skip. People start to see phantoms of themselves, events of the past long forgotten. Manaka makes one last visit, to her mother in the hospital. Since Manaka was born, her mother had lost her short term memory, and could not remember anything for a long time. She even forgot that she had a daughter. However, Manaka arrived as light, and restored her memory using the butterflies. For just a moment

One year after the 11th episode, these events occur. Toka is going to take an entrance exam when she detects trouble. Indeed, as the manticore is still alive; it possessed the writer when the manticore was originally destroyed by Boogiepop Phantom. Boogipop comes and destroys both the manticore and the writer, who had actually died a long time ago. Boogiepop then says, ""I feel sorry for Toka Miashta. She was supposed to be taking an entrance exam now."" Thus the series comes to the end, with us only just knowing who Boogiepop really was.
