This paper toy is a chibi Saya Otonashi, the main protagonist of the Blood+ (pronounced as "Blood Plus") anime series, and the first born of the daughters of the Chiropteran Mummy, the papercraft was created by Larry-San.
Saya is a pure blooded Chiropteran queen and Diva's older twin sister as well as Hagi's lover. At the Zoo, Saya is spoiled by the original Joel, and therefore becomes very immature, self-centered, and rude. She herself realizes this as a result of her friendships with Diva and Hagi, which help reveal and nurture her compassion for others. Overall, however, Saya is a bright, cheerful, and innocent person. After she unwittingly releases the vengeful, bloodthirsty Diva upon her foster family and friends and accidentally turns Hagi into her chevalier, coupled with learning the truth about her life and her own inhuman nature, Saya loses her happy demeanor and becomes much more serious and plagued with doubts and guilt. She dedicates her life solely to correcting the mistake she made in releasing Diva by killing her, then forever ending the chiropteran threat by killing herself.
As a result of losing her memories and spending a year in Okinawa as an ordinary girl, with family and friends, Saya develops a sweet and caring albeit somewhat reserved personality. Kai later refers to her as being "a crybaby and a glutton". The latter name suits her as she is much inclined to eating. According to Kaori, no matter how much she eats, she never gets fat. The constant hunger is possibly due to insufficient consumption of blood. At this time, she is troubled by her amnesia, but only becomes increasingly insecure and worried as she learns more about her true identity and experiences more loss because of the chiropterans.
A year after Riku's death, Saya exhibits a much darker and embittered disposition, having fully regained her memories but in the process of lost hope, as Moses and Lulu both note. She is unwilling to associate or work with others, particularly Kai and the rest of the Red Shield, not wanting to have to experience losing more loved ones. During the last half of the series, she slowly comes to accept their help.
In the last episode, Saya tries to save Diva after having delivered her a fatal wound. She is persuaded from not killing Diva's daughters or herself, leading to her confession that she does want to live. [Source: wikia]
