...you know when I first played the game, I thought it was a lot like Q.
Suddenly there's a timeskip, everybody hates you, and then you find out that it was all your fault.
I'm really glad that Shinji didn't get the oyasumi ending.
Though if you really wanted it to be accurate, Kaworu would have to be Basil.
Mari(evangelion) as Kel
Misato as Hero
Asuka as Aubrey
I'm Rei as Mari (omori) doesn't really fit, but she does dramatically die before the timeskip, soo...
though it also feels like Rei should be part of the trio.
Though of course you could also have Kaworu as Mari and Rei as Basil.
...at some point that fanfic would get super confusing as both stories have a character named Mari.
