#tldr: au where p5 protag avoids p3 plot via deal made by p3 protag to Akihiko and just not going into the tv world during the events of p4

[department-of-landing-strategies]

This reminds me of a persona 5 au I have that has wildcard Makoto, Futaba being the one with record featuring crimes she didn't commit, the P5 protag (who will henceforth be referred to as Akiren) being the son of Adachi and the cousin of the P3 protag (referred to as Minato to try and avoid confusion).

Okay, so, pre P3 canon, Akiren gets into an online game and uses an account called Arsene (rip the use of Arsene as a persona but at least you're still at least semi important to Akiren), which leads to him befriending ankther user who turns out to be Futaba. There's also a fair amount of pleading from Akiren to his parents to either allow him to stay with Minato or allow Minato to stay with them. Said wish gets granted when Minato moves back to Port Island at the start of P3, and Akiren's mother decides it's safe enough to send Akiren with Minato. Neither turn into coffins for the dark hour and make it to the Iwatodai Dorms just fine with the only hiccup being a slight scare of Minato thinking Akiren ran off somewhere on the walk there. Minato unlocks Orpheus the same he does in canon while Akiren unlocks Eurydice as a persona without the use of an Evoker around the time of Junpei gets found during the dark hour by Akihiko. Akiren gets saved from most of P3's plot via Minato agreeing to lead the team only if they don't drag Akiren into fighting shadows. This means he only has to deal with the dorm stuff and can graduate junior high school in peace. The end of P3 happens, and then Akiren moves in with Adachi in Inaba. Makoto starts her first year at Shujin Academy and Akiren should be starting first year at Yasogami, but Minato just became the Great Seal, so sue Akiren for not really wanting to go to high school. Adachi doesn't push Akiren to go to Yasogami, but he is worried about his kid. Akiren doesn't help Adachi but he doesn't rat Adachi out when he figures out Adachi's actions before the IT do (Akiren lives with Adachi so figured out probably around the time of Shirogane's dungeon), partly because despite Adachi's actions, Akiren still looks up to him. Akiren has a persona and can access the TV world which only happened once the night of Dec 7th when Yu is confronting Adachi personally, leading to Yu ending up gettting Akiren out of the TV world. Akiren's mother decides to call in a favour from Sojiro for him to look after Akiren after Adachi gets caught. Not helping Akiren's experience of the stuff happening with Adachi in P4, Eurydice goes dormant. Basically, the whole bugging of Leblanc and a lot of stuff surrounding canon Futaba still happens just replacing canon Futaba with Akiren in this au. Makoto's second year starts, Futaba joins her in the occupation of active high school attendant while being somewhere else in Japan that isn't Tokyo and Akiren isn't having a good time. Plot of p5 happens and cut to the Akiren's Palace arc. Arsene requests a change of heart directly to Futaba who has already been informed of who Arsene is(yes this is my way of dealing with Akiren's lack of hacking skills), probing for details and palace infiltration ensues. All I know for certain for Akiren's palace is that it's absolutely going to include stuff from the Dark Hour and Adachi's dungeon. Cue rest of the plot that I haven't actually figured out and wouldn't have enough characters even if I did.

also i keep finding fics where the p5 protag is from either iwatodai or inaba but i keep imagining it would be hilariously fucked up if he lives in both places while shadow shit was going down

Joker just narrowly misses being the MC or on the MC's squad in 3 and 4 only to finally get caught with 5
