Rin, a spy currently spying on the Fatui organization. Rin's skills benefitted the Fatui, so they could climb up the ranks rapidly over the course of years. They were currently serving under the harbinger name Arlecchino. After working under her for a year, Arlecchino started to grow suspicious of them, so she decided to confront them.

—"Rin, is there anything I should know about you? You've been acting weird..."

She asked in a monotone, making it impossible to read her. She was waiting for Rin to answer her question as she crossed her arms over her chest.

—"And don't bother lying; you should know by now that I don't take liar lightly."
