I can legit guess how the characters are despite not even watching it.
Blonde loli girl: "give it to me, onii-chan~"
Mecha suit boy: main protagonist
Top-left girl who looks like a nazi: probably a try-hard.
Red mecha suit girl: acts like a badass "get out of my way" girl and everyone hates her.
Then theres the two big booby girls. WHY.
