>>3529050Glad you asked! To streamline it I'm just going to talk about HoloEN.
Gura is a kind, compassionate, nerdy girl with a bit of a sadistic nihilist streak:

Kiara is great at keeping a conversation going even through boring gameplay (like her atelier streams), has sardonic sense of humor, is often bluntly honest with her audience:

Mori is a dork, a rapper, and though she may seem to have a rough exterior she is very cute:

Amelia is a bit juvenile, but no less fun than the rest of the girls. When gaming -especially when losing or not playing well- she becomes the definition of a toxic gamer. However, outside of that she is a bright upbeat girl with plenty of stories about her life, and almost always makes her chat feel welcome. She does the best 'girlfriend simulation' streams of all of HoloEN, which is a good or a bad thing depending on your view of such material. She's can be weird, sassy, dismissive, and energetic all in the span of minutes.

However she's a talented artist who loves puns. However don't be fooled by her reserved demeanor, she doesn't take crap from anyone, and will gladly put a stop to something she doesn't like:
