Vampire Knight: Lonely Son Of The Eternal Phoenix

Yuki's earliest memory is of a stormy night in winter, where she was attacked by a rogue vampire and rescued by Kaname Kuran, a Pureblood vampire. Ten years later, Yuki is the adopted daughter of the headmaster of Cross Academy, Kaien Cross, and has become a guardian of the vampire race, protecting her childhood crush, Kaname, from discovery as he leads a group of vampires at the elite boarding school.

At her side is Zero Kiryu, a childhood friend whose hatred for the creatures that destroyed everything he held dear leaves him determined never to trust them, and another, a young boy named Heart.

Unlike his two classmates, Heart belongs to a new group in the academy called Logos, a class of mystery whose studies are of legends, myths and fairytales. There, he and a handful of students are taught the ways of a style of swordsmanship called "Sacred Sword Style", a form of techniques taught by certain individuals who wielded strange incredible powers with the use of book items called Wonder Ride Books.

Out of all of his classmates, Heart doesn't have a Wonder Ride Book and a special Seiken of his own, thus, he is shunned and mocked by the lower and upper class alike.

But, one night, everything changed. Hearing a voice, Heart discovers a black and orange sword and with it, a Wonder Ride Book he had never seen before. With the flames of the mythical immortal firebird, Heart will burn away the sins of the impure and cast them out to the Void while returning all to nothingness with his own hands and by his own path of justice.

The wheels of fate now turn as Heart is put through a series of events regarding about the humans, vampires....and his past who he has no recollection of.
