Nagisawa Shichi Is Named the “Success Story” as Four Mixstgirls Finish Machine Party
Shichi, Kotomiya Iori, Narumi Myao and Yukishiro Qalu worked through a run of elimination mini-games before the ending revealed the cast as test subjects.
MIXSTGIRLS — Four members of Mixstgirls played the party game Machine Party together on Oct. 28, working through a string of elimination mini-games until the game’s ending cast Nagisawa Shichi as its one “success story.” Shichi, Kotomiya Iori, Narumi Myao and Yukishiro Qalu took part, and Shichi, Iori and Qalu each streamed it from their own channels over about 72 minutes.
The evening opened with a few minutes of audio fixes after word came that the members’ voices were not reaching viewers, and a game-audio problem on Qalu’s end was cleared up later by reconnecting. Once the game got going, it moved from a minefield crossed with a sonar scanner to a memory-sculpting task, then to a stage where players built a gun at a workbench and used it on one another. One of the participants announced she would kill everyone, and another asked to be on the side doing the killing. In the hunter-and-runner stage that followed, the others marveled at Qalu’s shooting: “Qalu is good. Scary. Qalu is scary.”
“The success story is Shichi, so there you have it. If you want to become a machine too, copy Shichi.” — Mixstgirls, after the game’s ending
As Shichi’s stream title, “I’m going to betray the members,” promised, the later stages leaned on betrayal. In a floor-tile stage the players knocked one another off the platform. At a dinner table, the rule was not to eat while the host was watching, and Iori cleared her plate first, while Qalu’s one-bite-at-a-time pace drew laughs from the others and from chat. A farewell scene in which the players said goodbye and ran toward a sunset was cut off by an on-screen warning of an unauthorized outside change, and the participants could not tell whether it was part of the game.
An infection stage came next, with players hunting for a syringe and then calling out Iori’s name as the last healthy player to find. Stages of throwing a device, dodging rotating blades and carrying crates by forklift followed, the last under a rule that the least efficient player would be dropped. The final task, sorting items into recycling or incineration, produced a tie that sent a round to a rematch. The others called Shichi seriously good at it, and chat read it as a clear win for her. Eliminated players thanked one another for everything.
A message then declared every simulation finished, and the game revealed that the cast had been part of an experiment and were not human. One voice said they were all failures, and Shichi was the one counted a success. Afterward the members said it was deep enough for a movie, called it scary in an experimental way, and one wondered whether the earlier error screen had hacked her game and cost her a win. Closing out, they joked that anyone who wanted to become a machine should copy Shichi, added that they did not recommend it, and said goodbye together. Chat answered with congratulations to Shichi.
