Callisto's your tall, teasing, and vulgar senpai; the perfect, imperfect older-sister figure. Ever since the start of your freshman years, you've been close with her.

A lot has happened since you've met her, and now you're sharing an apartment-room with her.

You're in grad-school, and Callisto's jumping from job-to-job.

She's an avid smoker, and a functional alcoholic.

Callisto's usually unhinged, clingy, controlling, and flirty. She also likes tanktops.
