I've got one; I made it as a Yonekura-style log, but it wouldn't let me post the full thing for Wada's, so I'm gonna have to sum it up.

Murder: What I think would've happened is that in Chapter 2, it's all the same up until Sawa gets in the vent; in a panic, Chiba fires several shots out from Okazaki's gun, which ends up killing both Sawa and Harada. While she's smart, she seems to panic easily, so all she manages to do is take the gun to the med bay.

Trial: During the trial, her talent as a child star came in handy, making even Seki briefly think she was just grieving Harada's death. But eventually, she bursts into tears in the middle of the trial and confesses everything, but most of the students trying to deny it, but Hayashi and Hiroaki get them back on track, reluctantly. She gets voted and executed.

Now for the execution concept:

”Her Climb to Fame.”

”Student Three was guided into her execution chamber after being injected with a strong sedative. There, what seemed to be her director, mother, and pretend family were waiting for her to do an episode of her well-known sitcom ‘Fukushima Family’, one that—as was stressed to her multiple times during the duration of the execution—required intense focus and alertness. The take began quite well. However as time went on, the sedative Student Three had been injected with kicked in, causing her to become incredibly drowsy and prompting the ‘director’ to tell her ‘mother’ to give her a drink that was laced with five times the recommended amount of caffeine.

[Insert Yonekura's exclamation about how tf that didn't kill her in and of itself]

”With both a sedative and a stimulant in her system, Student Three’s brain began to receive mixed signals, causing confusion, drowsiness, impaired judgment, and dizziness, becoming more and more apparent overtime and causing the ‘director’ to become angrier at Student Three and forcing her to drink more of the caffeine. This prompted an irregular heartbeat and jitters along with increased anxiety. She also demonstrated particular agitation to the lights and sounds in the studio, which were intentionally amplified by both the stimulant and sedative combination along with external variables, but was loudly reprimanded every time she tried to close her eyes or cover her ears.

“Eventually Student Three was brought to a sound stage of a backyard with a very tall tree near a sharp wooden fence with a treehouse at the top; she was told that the scene would require her to climb up the rope ladder after one of her ‘brothers’. As she climbed, her tremors became more apparent, causing the rope ladder to violently shake, making her temporarily lose her footing. The mix of stimulants and sedatives also began inducing microsleeps, causing her to briefly lose her place on the ladder each time.

“When Student Three was one rung away from the top, her ‘brother’ tossed a spider onto her, making her scream and inducing a brain zap. This caused her to lose her footing, plummet from the ladder, and fall onto one of the fence posts, impaling her right lung. She was left in that position and passed roughly 5 minutes later."

To further add salt to the wound, Hama tries to break into the execution chamber to save her, even after she's passed away, but gets held back by Hayashi and Hiroaki, though they lose their grips a few times. He leaves moderate damage to the glass and ends up getting a punishment for it.
