Persona 3 x Fallout Crossover Challenge

Had a dream about this last night and I wish to read a crossover between the two

Characters: Minato Arisato, Aegis

Pairings: Minato x Mitsuru (previous), Would prefer if Minato and Aegis would have a familial relationship, Future pairings (?) don't really care but no harem please and I would prefer that romance won't be the central point of the story.

Genre: General/Psychological, Angst, Adventure

Abilities: Diminished. He can only just summon Orpheus (telos?) and Thanatos and magic. No velvet room

Basics:

*Mitsuru has Minato's body on life support at a secret company's hospital. Only SEES and staff knows about it

*Main researchers for Minato's recovery? Revival? are Mitsuru and Fuuka

*Everyone is older only Minato's body is apparently in stasis. Still how he looks like when he was in school

*Mitsuru makes video logs of research/ongoing events and thoughts addressed to the subject (minato)2nd is Fuuka , the rest of the group also occasionally does too but not that much.

*Ongoing world war outside. In response to the eventual Nuclear war, Kirijo group also build a vault. Moves staff and minato in one of the highly sealed and secure room.

*SEES and only limited people of Tatsumi port island can enter the vault since they don't have enough time to expand the vault

*Time skip, everyone is showing signs of age (except minato). With the ongoing war and rising death counts, Minato's body shows signs of life. Since he is the seal for humanity's hatred, the dwindling number of human lives affects his state of being.

*Mitsuru is torn between being thankful and horrified at that thought. (maybe?)

*It was concluded that Minato's recovery is imminent. It would only just take time.

*Everyone moves to the vault. Nuclear fallout is near. There is war outside the vault because of people trying to get in. Aegis and Labrys are the main fighters that prevents surplus people from going in

*Before the fallout, Labrys managed to push Aegis inside the vault before it is shut. Then bomb falls.

*Bring in the Psychological and emotional drama for the group

*Ongoing life ensues. Mitsuru is basically the overseer. Everyone is old. There are leaps in technology inside the vault, basically armaments. Fuuka made a modified version of the pip boy and secured one on minato's wrist. (with guide on how to fix aegis maybe? Your choice)

*Monsters get in the vault, Aegis was tasked to stay inside Minatos's room and the room was sealed. Everyone dies.

*X amount years later, power starts up inside the sealed room when minato wakes and this is where his and Aegis adventure starts. Go wild. I want you to make me drown in Feels :3

Thank you for anyone who decides to answer this challenge. ^_^
