I love how movie subtly implies just how badly reze yearns for a normal life. Yes we are told she never got to school but
>reze studies geography in her spare time at her job
>is very self aware, realizes she is just a kid and that childhood/teenhood was stolen from her
>when telling denji what he is missing from not going to school she tells very idealized idea of school life, almost as if taken from a slice of life anime
During firework scene she asks denji to run away and I always took it as her ploy to lure him into a trap, but I now lean more towards a more romantic motive. I believe she only started to think about the mission when she felt betrayed by denji
Also, seeing a shadow cover her as life exits her eyes unlocked a trauma I did not expect from this arc.
