GEHENA Labs has uploaded a subtitled video of "Let's Go Find Some Fun!" and since it's my favorite memoria story, I'm going to talk a whooole lot about it.

Yeah, this picture isn't from "Let's Go Find Some Fun!", but I'm gonna talk about Tazusa first, so...
I think Assault Lily is not very realistic in that, with a few notable exceptions, it rarely shows the girls suffering any mental consequences because of the battles they fight. They're teenagers; it feels to me like when other people, sometimes their friends and loved ones, get hurt and die right in front of them, those Lilies who are able to just brush it off and keep going ought to be an exceptional few and not the vast majority.
While it's nice in a way that the stories never revel in traumatizing the characters like some "dark magical girl" anime do, it's also a shame that they rarely attempt to explore how the grief and regret caused by death affects people, in the manner that Assault Lily Bouquet did. It was one of the things that made me fall in love with the setting in the first place.
There are exceptions to Lilies taking death in stride, and one of the more subtle ones is Andou Tazusa.
