This paper toy is a chibi Hagi, Saya's first, and only living chevalier and also her love interest, based on the Blood+ (pronounced as "Blood Plus") anime series, the papercraft was created by Larry-San.
Hagi is nearly always seen wearing a charcoal suit that has two front and two back tails of equal length. The jacket has a narrow black band at the waist and a black buckled band on his Chriopteran arm. He pairs the jacket with a white Barrymore shirt, charcoal trousers and black shoes. In the flashback to the Russian village sequence, he is shown bare-chested with a towel around his lower torso. He is also often seen with his cello case, both a genuine instrument vessel as well as storage for Saya's sword.
Although Hagi is over 140 years old, he maintains the look of a 25 year old man because that is the age at which he became a chevalier. Despite his origins being a complete mystery, he is said to be of Eastern European descent. He is quite tall, has fair skin and jet black hair that falls to his shoulders with somewhat wavy bangs falling over his eyes. His eye color is pale blue which turns crimson when his Chiropteran powers are unleashed. He usually keeps his hair tied in a ponytail at the nape of his neck with a blue ribbon. In flashbacks, he is shown to have let his hair remain unbound. [Source: wikia]
