...Do I... even have character types...? Umm... Okay, let's see...

Reisen: A rabbit. Hard worker who is essentially slave labor to a moon refugee. Largely seems to like her job.

Suika: An oni. Hobbies are making everyone happy! But has zero empathy and just kind of assumes what makes her happy would make everyone else happy too! So everyone should get durnk, party, and fight!

Helion: Basically a puppy. Homunculus "born" to be raised as a sacrificial soldier as slaves to the country and treated like monsters. Gets addicted to the praise she gets when she does a good job.

Tries... really really hard to be awesome. Is actually kind of a loser.

Kozue: Bright, cheerful, talkative... And also a mute, barely restrained homicidal maniac.

Mayu: Guiiilllt compleeexxx. Does her best at everything because she believes that she is a terrible person for making people unhappy.

Kirara:Super genius who is secretly chaotic evil to avenge her unrequited love's death, but also loves people way too much to actually go through with it. Usually.

Nepgear: Basically a walking Lawful Good stereotype. Has some family issues.

Uzuki: GANBARIMASU!

I... Guess I have hard workers as a type? Sor tof?

Kozue can't really be considered a workaholic like the rest, though...
