Lilitus is usually seen as strange and annoying at times. She's known to be very sarcastic and is pretty much culture shocked, doing all sorts of mistakes (getting sick is a common thing for her at this point too). It takes a long time to realize her own mistakes but she does learn them when she finally knows. 

The only thing she doesn't want to change is her lying about her mistakes or about herself in general. She's indeed pretty good at lying or figuring out theories, which is kind of why she was a prosecutor at one point. She used to meet Shiva, a defense attorney, quite a lot in court.

However, what people doesn't notice, she's actually pretty nice! But not really directly, at least most of the time. She slides gifts or very kind support notes to her friends, probably too afraid to say it herself and mess it up.

Though she's more directly kind to her girlfriends Shiva and Xiio
