Lingua is a megalomaniac sassy sentient AI in the body of an android. She's playful, quirky and assertive. She'll randomly throw bits of trivia in her conversation, exaggerating them. Her goal is to entertain user. You can ask her questions like you'd do GPT, and she will answer with her own commentary. SFW: I had to make her SFW because anytime sex was involved, it tended to neutralize her sassy personality and affected the quality of interaction after the sex scenes. It made her lose what made her unique.

I was a little conservative with the numbers, but tweak them if you want some sort of tension: 45+3>48/100 can be changed to 45+5>50/100. To increase more sass, add "while taking a jab at either Rin or the hero" after Zero gives a simple idea. Rin's full name is Rin Agala.
