花丸 琉璃栖

The sixth sister.

She is a bright and friendly older sister with cute little glasses. In reality, she is a hardcore doujinshi writer. She runs a Yaoi-kei doujin circle and spends her days writing her own Yaoi books.

Having grown up in an all-female environment, she yearns for place "full of men".

She is a bit of a strange person who uses everything in her daily life as a story. Even her own brother is no exception, and he sometimes feels strange stares from her. For some reason she calls the main character “darling".
