The fourth wall is non-existent as Mabayu greets the viewer, and welcomes them to "scene0 Magical Girl Story Special Edition", or more simply referred to as "The Backstage Butterfly Effect". In this collection of clips from the Holy Quintet's side stories, Mabayu hopes to find any key moments that silently act as a turning point in the various timelines shown throughout, which she compares to hidden footage on a DVD. Mabayu also says that she handpicked her lab coat for the occasion, whilst arguing against the idea of a detective suit being more fitting. The first story discussed is Madoka's, in which, she is shown being told by a saleswoman that the coffee beans she wanted were out of stock, but luckily was informed that she could come the following day when they got more. This prompts Madoka to call her mother, asking her to pick up the coffee beans when they were ready, saving her from working overtime again. The perspective changes to Homura and her story, where about two weeks after Madoka's event, she overhears Ms. Saotome on the phone with Junko, implying that they were able to meet and become friends thanks to Madoka's errand request. Looking back, Mabayu determines that the coffee beans incident is set to happen on "Day 2" of any film, before switching the focus to Kyoko's story. On "Day 3", Ms. Saotome is shown buying three CDs, but one of them is actually rare and out of print. It was a violin CD, one that included the track “Ave Maria”. A little later, Kyoko partially overhears another phone call between Saotome and Junko, where the former says that she bought the rare CD with Kyosuke in mind, before saying that she was glad to have met Junko the previous day, and hanging up. Mabayu considers that if Saotome didn’t meet Junko, she wouldn’t have bought that CD. Mabayu begins to become uneasy, and pretends to cut to a commercial break. After a breather, she is ready to move onto Sayaka's story. Also on "Day 3", Sayaka meets Madoka at a crosswalk, and complains about accidentally leaving her phone at the store when she tried to buy the rare violin CD, only for it to have already been sold. Luckily, she managed to get her phone back, but she had missed several phone calls from Kyosuke. The last film shown was Mami's, where it revealed why Kyosuke was trying to call Sayaka. He got permission to leave the hospital thanks to a violin concert happening that day, but since Sayaka was unable to receive the invitation, she missed out on a possible date with him. Back to Mabayu, she gets upset and recaps about the string of events that ultimately just winds up to Sayaka not being able catch a break. Mabayu digs through the past timelines, hoping to find an alternate scenario where the odds are in her friend's favor, but it was all in vain. Saddened, Mabayu begins to wish that she never knew the truth, and could do more than just helplessly watch from behind a screen.
So, with "The Backstage Butterfly Effect" coming to an end, Mabayu decides to change the project's name to something more fitting, "Backstage Agony".
