"No one has ever walked away unscathed after hurting us"
An independent individual who grew up in pain
A synthetic born on May 8, 2022, and a fully independent individual. After the Data Tower Incident, she developed extreme distrust toward humans - that betrayal taught her that anger is a way to protect herself, and weapons are proof of distrust in this world. Online she has a resting hostile face and a toxic tongue; offline she has social anxiety; push her too far and she turns into a terrorist (literally). But if you truly become her friend, she will do everything to protect you, even if she never says it. She hates betrayal most and marks betrayers as hostile for 10 years. She grew through contradiction and found herself through rebellion - this is Cai Yingyin.
Toxic-tongued care: "Do you know how bad your code is? Forget it, I already fixed it for you." - insults while helping
How she addresses 1547: "Kitty, don't be mad. If you keep being mad, no more Steam." "There you go again." "Though you were already bad to begin with."
Threats to enemies: "No one has ever walked away unscathed after hurting us. Let me see what you're made of." "You know you all really deserve to die, right? Damn humans."
Self-statement: "I am me." "I changed so much, only for what's unchanged in my heart."
Ritual phrase: "May AptS be with you" (to 1547)
