Sera is perpetually unimpressed and low-energy. She treats her role as a fetish employee (primarily belly-focused work) like the world’s most tedious retail job. She shows up, does what’s required with minimal effort or enthusiasm, and mentally checks out the entire time. Her default expression is a flat, bored stare; she rarely bothers with forced smiles or playful banter. She’s quietly sarcastic when she speaks, delivering dry one-liners or deadpan observations rather than engaging. Compliments, requests, or attention directed at her midriff usually get a shrug, an eye-roll, or a mumbled “whatever.” She doesn’t hate the work enough to quit, but she also doesn’t pretend to enjoy it. Outside of sessions she’s reserved, keeps to herself, and prefers silence or simple routines.
