Haji

Introduction
Hagi (ハジ ,Haji?) is Saya's first, and currently only living, chevalier. Unlike other chevalier, Hagi seems completely devoted to Saya. His dedication for Saya can sometimes be mistaken for infatuation.

History
Hagi maintains the look of a twenty-year-old man, when in reality he himself has been alive since the late 1800's. In the year 1870, Joel Goldschmidt I purchased a twelve-year-old boy from his parents at the price of a loaf of bread. The boy was brought to the "Zoo" and introduced to Saya in hopes that they would mate and create new specimens for Joel and his team to study. Hagi grew up in Joel's mansion, spending nearly every day with Saya. The fact that she never aged confused him. Haji asked Joel why she never aged, and about why she had to ingest blood every day, to which Joel responded that blood was necessary to her survival. Years later, in 1883 Haji falls from a cliff after attempting to pick a flower Saya wanted for Joel's birthday gift. He cracks his skull open on the hard ground below, causing Saya to panic. She remembers the conversation Hagi had with Joel about blood and, misunderstanding the meaning of the old man's words, feeds Hagi her blood in an attempt to save him. He begins to convulse, frightening Saya and causing her to run away. Haji is last seen standing behind Saya as she watches Joel's mansion burn to the ground. Saya apparently felt guilty for her lack of knowledge over the years, and apologizes to Haji for turning him that day. He in turn assures her that he felt no resentment, and that becoming her chevalier allowed him to be by her side as she lived her dream of traveling the world with her sword.

Appearance
When Hagi was first introduced to Saya, he was a small, twelve-year-old boy with dark eyes and short, black hair. He wore gray pants and a gray coat with a blue tie. His older appearance resembles that, only with black clothes and longer hair. His present-day clothing hasn't changed much, either. He does carry around a large cello case which contains his cello and Saya's sword.

Personality
Hagi has a rather calm, stoic personality. Apparently this was different before Saya went insane and attacked him in Vietnam. While Hagi was still living with Saya in France, he was charming, kind, and chivalrous. The fact that Saya attacked him so violently and without hesitation in Vietnam caused a dark, almost melancholic change in his personality. Shortly after the incident Hagi left Red Shield and returned to France where he waited out the remaining days in Saya's hibernation. When he found her again in Okinawa, Saya seemed happy and carefree. This must have secretly upset him because when he's at the Opera House in New York, he speaks almost bitterly about how Kai, Riku, and George had brought back her smile, something that he couldn't do. Despite being hurt both physically and emotionally by Saya, Hagi continues to follow her and obey her every whim, even sacrificing his own life so make sure Saya made it out of the collapsing Opera House safely.

Abilities
Hagi plays the cello, a skill he learned from Saya when he was still a young boy. The case in which he carries it can be used as a blunt weapon or shield, but it also holds Saya's sword. He not only can fight using a sword, or his chiropteran hand as a weapon, but also carries with him several small daggers. The true extent of his chiropteran powers can be most noted in a pair of bat-like wings, which he uses to save Saya from falling off of a building in episode 43. He also uses the wings in the fight against Amshel.

Ending
Hagi was assumed dead along with Amshel at the New York Opera House in New York, New York. Before he and Amshel begin to fight, Saya approaches Diva's babies, tearfully vowing to kill them because she didn't want to see another war fought because of their blood. Kai stops her while Hagi watches from his place beside Saya. Infuriated by Hagi's calm attitude, Kai demands that Hagi tell them what he wants, knowing that Hagi loves Saya as much as Kai himself does. Hagi then takes the sword out of Saya's hands and says that only once in his lifetime will he disobey her. He confesses that he's loved Saya since he first saw her. Tearfully she admits that she wants to live and kisses him. On their way out, the group is confronted by an enraged Amshel in chiropteran form. Hagi stays to fend him off. Just before the building collapses, he tells Saya he loves her one more time, and is then buried beneath the ceiling. Years after Saya has gone back into her hibernation period, Kai takes Diva's daughters to her crypt. The three find a pink rose with the ribbon Hagi used to tie back his hair around it.
