Review Detail of Preyas in Nanomancer Reborn - I've Become A Snow Girl?

I just writing a review because of the PTSD arc and how trash it is I know it is "character development" but it is not I find relevant to the MC at all. like it feels she got over killing her friend herself more easily, rather than fighting a god/tier 8 to save her friend while being injured and losing in the end she took so hard she was struggling to get out the room. I like reading this to past the time but damn the PTSD arc was so trash
