Blue if the first 5 deaths were the survivors instead(Warning: Cult Arc rehashed in Chapter 3)
Ch1: Kumada never got into the elevator, preventing her, Yaitabashi, and Hirose from becoming friends. The new pairs are as follows: Kumada-Yokoi, Denden-Ogura, and Ouno-Akiba. Akiba and Ouno more or less have a Boke-Tsukkomi dynamic, which keeps her occupied from planning a murder. Akiba also forms friendships with Maekawa and Matthias so he gets more character dynamics. Denden's friends are Hirose, Isoda, and Ogura(and Matthias too). During Voter Game, Kumada tries to pile the votes onto someone(Ouno suggests Ogura due to her distaste of her shenanigans), but Yokoi prevents that, to some extent. She volunteers for the No-sleep and No-food punishments and Kumada ends up with at least two punishments. So, Kumada takes advantage of Yokoi's state and stabs her multiple times. She disconnects the cuffs and runs off to another place to pretend that she was disconnected when the murder happened. She tries to frame it on someone but it fails and Kumada is executed.
Ch2: The Bleeding are as follows: Maekawa, Nishiguchi, and Ikeda with the recruits being Shishikura, Yaitabashi, and Tei. Maekawa chooses to kill Hirose by sneaking poison into the meal Nishiguchi prepares for him since he seems like the smartest non-Bleeding member in the group. With her Magical Powers and Matthias by her side, Ogura MVP's most of the trial until Yaitabashi gives in and confesses the whole plan, straining his friendship with Nishiguchi as it was their only chance for all six of them to survive. Maekawa's last words were to pass down her Morning Show to Akiba and to tell Shishikura that she liked him. Maekawa is then executed, which leaves Shishikura absolutely devastated.
Ch3: "Don't you worry Hidemi, I shall ensure that you and Ikeda Daiki escape your situation in Kobe." As Ouno tries to push the microwave above the shelf using her crowbar towards Ogura's direction, the announcement sounds. "Ding Ding Ding, Diiing, Ding. Attention Students. A body has been discovered." Startled, Ouno pushes the microwave wrong and it lands on Matthias instead, and a second announcement plays. Isoda panicks as they look for Denden because they don't want to lose her like the two lost Hirose, but what they saw was indescribably horrifying. Denden covered in blood with her eyes replaced with 8-balls as Tei and Shishikura are drenched in her blood with the latter writing using it. The three of them are then startled by the second announcement, and Isoda runs away screaming. Meanwhile, Akiba, Ninomiya and Ogura are absolutely devastated by Matthias' death and since Ouno was startled, she couldn't run away and was caught. Ogura then finds out that Denden died too, which puts her out of commission. During the trial, Ouno is implicated immediately, but the group can't tell whether Tei or Shishikura were the blackened. Due to the stress of the Killing Game and his eyes, Tei is severely stressed. Monomoko tries to help him by getting his eyes fixed and even puts him to sleep so he can recover. However, Tei saw Monomoko's domain and everything went wrong. Tei starts rambling about millions of eyes and teeth and it creeps Ikeda out. Shishikura, wracked with guilt that he helped with the Bleedings' plan and grief that Maekawa was executed instead of him, and Denden, devastated over the loss of Hirose, and without him to lead her away from the cult, is sold on Tei's cult. Tei mistakes Monomoko's domain for The Afterlife and is convinced that he can open a portal to save Yokoi, Kumada, Hirose, and Maekawa. And so, he devises a plan that involves the other two members. Denden absolutely refuses to kill Shishikura but he, who wants to be executed so he can join Maekawa, agrees to kill Denden, and she complies. Denden drinks a cup of poison from Shishikura and when the announcement played due to Tei's presence, the two immediately get to work. Shishikura ends up confessing and is executed.
Ch4: After Matthias' death, Ogura is holed up in her room, grieving. Akiba brings it upon himself to check on her, starting the friendship they couldn't start in Chapter 1 due to the circumstances. Akiba's also keeping watch over Ouno, but she won't leave her room. Ogura, however, eventually finds it in her to go out again. Since Yokoi was never able to steal Ninomiya's insulin, he runs out faster than he did in canon, and due to Hirose's absence and Matthias' death, he's very desperate to escape so he can live. He chooses Isoda as the target because they're easier to access than people like Ouno, Ikeda, or Nishiguchi. He tries to hit Isoda on the head but he's so sluggish that he stumbles around and even hits their shoulder instead. Isoda, falling into despair due to Hirose and Denden dying back-to-back, understands why Ninomiya's trying to kill them, so they just let him finish them off. Ninomiya's defense was that he was too weak to kill them, but Nishiguchi points out from her own experience that the contusions were spread out in such a way that she can tell that they were caused by someone who can't think straight. Ninomiya is then executed.
Ch5: By this point, Yaitabashi and Nishiguchi have made up and their bond gets stronger, Ogura and Akiba develop the friendship more and Ouno's being cordial with Ogura since she'd share a mutual friend with her(It's Akiba) and she'd eventually figure out that Ogura actually cared about Matthias and didn't see him as a mindless follower. Tei, however, is spiraling further and Ikeda is scared for him and scared of him. He's still going on about Monomoko's Domain and Ikeda can't do anything except watch over him since no one else would, and he's still Ikeda's main permission-giver for basic needs. One day, Tei just gets so scary and all up in Ikeda's face that he tries to defend himself and accidentally pushes Tei too hard and he hits his head on a hard surface and gets a concussion. Ikeda doesn't know what to do and since Hirose died, there isn't a medical professional left alive, so he thinks he killed Tei for real and runs into his room(They were both in Tei's room). Unfortunately, that causes Tei to die of bloodloss. Ikeda wakes up regressed, unable to remember what happened yesterday, goes to Tei's room and finds his body, triggering the announcement.(Huh?) Yaitabashi can't figure out who killed Tei because everyone else was accounted for but Ikeda triggered the announcement, but figured out that Monomoko played the announcement to make Ikeda seem less suspicious like how she turned Canon Shishikura's BDA off so Maekawa wouldn't be found out. Since this Maekawa died in Chapter 2, Monomoko was unable to form a super close bond with her, but it gave her more time to spend with Ikeda, which would justify her crashout when Ikeda was found guilty *and* comforting Ikeda at his execution, which happens in Chapter 5 now. Monomoko, feeling guilty that she caused Tei to get worse because she ruined his eyes, tried to fix them, but showed her domain in the process, which made Tei obsessive and that was what caused the deaths of Denden, Shishikura, himself, and now Ikeda. Monomoko's going to lose her best friend, Ikeda, because he got scared by Tei due to what she did to him. This is what sets up whatever arc she would've had in White.
