Chiho is a young girl who was confined into the Hiyamakai Hospital, owned by Higa Izumi, because she suffers from an aggressive, incurable virus. The medicine she takes is just slowing down the spreading of the virus but the medicine doesn't heal her.[1] She loves her Sekirei, Uzume, dearly and admits this openly. According to her, for someone who has lost her parents when she was young and has been lonely ever since, Uzume gave her purpose and meaning to continuing living.[1] She is ashamed that she can't do anything as an Ashikabi for Uzume due to her illness. Chiho has no idea that she is being used by Higa so that Uzume would commits crimes in order to protect her and Uzume stated multiple times that Chiho doesn't need to know about it.[2] Chiho first met Uzume when Uzume was running from M.B.I. the two began to trust each other almost immediately. After that, Uzume visited her everyday with her costumes and Chiho eventually became Uzume's Ashikabi. Throughout the series, Uzume has visited Chiho many times and her latest time was right after her failed attempt to take Minato's newly earned Jinki. Minato and his Sekirei kidnap Chiho in an attempt to free Uzume from Higas claws and transport her to one of MBI's facilities for treatment
Sekirei
In Tokyo in the year 2020, Minato Sahashi has failed the college entrance exam twice, is awkward around women, and unemployed. Growing up, he could never stand up to his mother or little sister, a trend that continues to this day. In reality, Minato is extremely intelligent, yet his inability to cope under pressure results in his constant failure. As a result he has been branded an idiot and loser by many. One day, Minato meets a girl named Musubi, who literally falls from the sky. Minato soon learns that she is one of 'Sekirei' and he is her 'Ashikabi', human with special genes that allows them to "wing" (ie. form a contract with) Sekirei. This binds the Sekirei to him and allows them to use their full power in the elimination battle with other Sekirei. Made up of cute girls, buxom women, and bishōnen, the Sekirei fight in a dangerous and sometimes deadly competition (also known as "The Game" or "Sekirei plan") organized by Minaka Hiroto - chairman and founder of the mysterious and powerful MBI Corporation. Minato soon learns that being the partner of a beautiful girl is not all fun and games, especially when he discovers that an Ashikabi can have more than one Sekirei partner, and that's where the real trouble starts.
