Countess Chelsea is a sinner whose threat level was assessed to be A-Rank. Felines. She used to have a pet cat (and as a Sinner demands to have some during an event) and acts like one too, such as purring for the Chief, asking for pets and generally behaving in accordance with her whims alone. Phase 2 of her Interrogation reveals she's had her cell turned into one not just with her own money, but with the help of the various sugar babies she has in the government.
