Do-S

Do-S was a Demon-level Mysterious Being and a member of the Monster Association. Do-S is a monster that resembles a human female with long, blonde hair with a black flower on the left side of her head. Her eyes are light(pink in Anime) with black sclera and has a pink, heart-shaped symbol on her forehead, as well as many piercings on both ears. She dresses in a BDSM outfit made of straps and held by metal rings revealing her figure; during certain scenes it's shown she has well-endowed abdominal muscles. Her attire is adorned with high-heeled boots, ripped by the side and ripped arm warmers. In addition, she also dons a mask with an S-symbol over the filters as well as a spiked choker. Her unmasked face has fangs and a long, flexible tongue. Like her appearance and attire suggests, Do-S acts in a similar manner to that of a sadistic dominatrix and princess like whipping at her opponents and expecting them to follow her orders to the letter. She also likes to toy with opponents she finds amusing, like Fubuki and suggests on using her against Tatsumaki. When injured enough in a fight, she abandons her dominatrix persona and becomes a ruthless fighter intent on destroying her opponent. When a fight falls out of her favor, she is willing to resort to desperate measures or cowardice, lashing out in desperation, then groveling to Sweet Mask, or sacrificing her slaves to flee from Tatsumaki. She's even willing to offer her services and accept powerful opponents as her master when truly cornered. While normally acting dominant, Do-S is proven to be submissive and shrewd when faced with Dragon-level mysterious beings, quickly making excuses to avoid punishment from Monster King Orochi after failing to kill Tatsumaki and Fubuki. She's always eager to add more slaves to her army, jumping at the opportunity to subjugate Nanriki's Squad and Atomic Samurai's disciples.
