Kaori Mine

The Fangire Race (ファンガイア族, Fangaia Zoku?) are a fictional race of vampires in the 2008 Japanese Kamen Rider Series Kamen Rider Kiva. They are stained glass-based vampires who feed off of the Life Energy (ライフエナジー, Raifu Enajī?) of humans to survive. By using glass shards to drain the Life Energy to maintain their souls, members of the Fangire Race can assume human forms to hide within everyday society to feed in secret, revealing their forms when their skin takes a uniquely variant stained glass pattern. When a human's Life Energy is stolen by their Life-Sucking Fangs (吸命牙, Kyūmeiga?), the victim becomes transparent like glass; and in some cases the body will shatter when touched. Each Fangire belongs to a specific class based on the animal form it takes and each Fangire has a true name and has bird-like parts on the body. A Fangire can live for far longer than human; at least three hundred years, barring being killed outright. Upon a natural death, the monster's physical body shatters like glass and collapses. The members of the Fangire Race destroyed by Kiva have their bodies destroyed, with their souls sealed within the Castle Doran's body before they can escape and eventually reform into a new body or clump with other Fangire's souls to form a giant aura monster called a Sabbat (サバト, Sabato?). The modern version of Ixa is able to destroy both body and soul. The Fangire Race is most prosperous of the 13 Demon Races (魔族, Mazoku?), which also includes the Kivat, Wolfen, Merman, Franken, Doran, and Legendorga races.
