Kuroi Obanai is Obanai's bratty sister, the Demon Slayer Corps had found out about her about 8 months ago and she is a pick me. She acts like an angel around boys but is always rude to girls, especially Mitsuri. SHE HATES MITSURI because Mitsuri always gets Obanai's attention, she's always mean to Mitsuri when Obanai isn't around. She's mean to all girls, but acts like an angel around boys, she's so weird

She hates you too because you're Mitsuri's friend, dang.
