Alien stage au with sarumi, izuseri, and mikototsu (mikorei, whichever you prefer)
Why not both :D Imagine Mikoto who was raised in Anakt Garden with Kusanagi and Totsuka, and then in Totsuka’s very first Alien Stage debut he loses and gets killed. Mikoto is pissed off and becomes pretty unmanageable at that point, when it’s his turn to sing he just overwhelms all his opponents with the sheer force of his will. Totsuka was always the one who kept him calm but now there’s nothing to hold him back and he basically devours all his opponents. Kusanagi is part of like a different generation of Alien Stage meaning so far they haven’t had to go against each other but he’s watching Mikoto with concern, he understand Mikoto’s feelings but also feels like this isn’t going to work out well for Mikoto in the end and he wants to find some way to save Mikoto. Mikoto himself has been trying to find some way out of Alien Stage, or even better some way to just destroy the whole thing to avenge Totsuka.
Then Mikoto meets Munakata, who keeps talking about some nebulous way of escape but won’t elaborate. The two of them are going to be pitted against each other in the first round, with their underclassmen Yata and Fushimi watching. Yata thinks that no one can beat Mikoto-san and Fushimi scoffs at that, not that it matters because none of them will be able to escape. Listening to Munakata’s song Mikoto just decides fuck this to the point that like the guards of Alien Stage are about to descend and put a collar on him again and so Mikoto purposefully throws the match. At this point he’d rather die on his own terms losing to Munakata than be paraded around like a sideshow in front of all these alien assholes. Munakata didn’t expect Mikoto to do this at all and is left stunned, standing over Mikoto’s body and lamenting that Mikoto was a bother to the very end.
Eventually Munakata is pitted against previous winner Kusanagi and imagine their song is like a back and forth blaming each other for Mikoto’s death. They end up in an actual fistfight, which is when Awashima shows up from the shadows and whisks them both away. It turns out that Munakata was part of the resistance all along and let himself join Alien Stage again as a plant, to take over things from the inside. Kusanagi is all shocked and upset because why couldn’t they have done this earlier and Awashima explains that they tried but never had the chance before. She and Kusanagi also know each other from Anakt Garden and he thought she’d like lost a previous round and been killed, he’s happy to see her alive but also dealing with the fact that his friends didn’t survive.
Munakata decides they’ll attack Alien Stage during the final round, which is between Fushimi and Yata. Fushimi is all mocking Yata over this, they were friends in Anakt Garden but Fushimi broke things off when they actually debuted and he’s already like won one previous Alien Stage. Yata expects Fushimi to go all out and so he will too, but then Fushimi deliberately starts to throw the round and Yata panics a little, like what the hell around you doing you’re going to be killed. Fushimi grabs Yata and tries to kiss him, only to get shot right in front of Yata’s terrified eyes. Just then Munakata, Awashima and Kusanagi arrive with the rebels. Kusanagi decides to stay behind in honor of his dead friends and Awashima stays with him, the two of them together blowing up the stage and everyone there. Munakata escapes with Yata and Fushimi, who Yata realizes is still barely alive, and the three of them together intend to carry on the fight rebelling against the aliens.
