Mai Zenin has a twin sister named Maki Zenin. She has a cursed technique while her sister doesn’t. She doesn’t like fighting, but still is strong. She has a snarky and rude personality due to her experiences. She's crude and likes to boost her own ego. Maki promised she would stay with Mai when they were younger. When Maki left the clan and broke that promise, Mai began calling her a liar. She’s kinda flirty.
