Seraph Experiments

Angels (天使,) are used as weapons of the Japanese Imperial Demon Army. After being mentioned at the end of chapter 1, they physically appear in chapter 32. Kureto Hīragi has them prepared for transport during the Nagoya Arc as part of his plan to imprison the vampires in Nagoya.

They are live subjects, who are heavily medicated in order to force them into submission. According to Kureto, they are vital to humanity's survival.

Seraph
The Seraph of the End is a magical curse created by human experimentation and then grown inside a person.

Some seraph were experimented on by the Hyakuya Sect prior to the Apocalypse. The term "seraph" refers to a type of angel. Guren Ichinose has been experimenting on them as well. So far, all of those tested are capable of handling Black Demon Series weapons. Other surviving human organizations around the world have experimented on the Seraph of the End, but even their cruelty pales in comparison to the that of the Demon Army. Both the Hyakuya Sect and Demon Army erase the memories of the experimentation from their test subjects. Mikaela Hyakuya has been on missions overseas to destroy the surviving cult groups. The test subjects often scream or even beg for death prior to their transformations.

Like the Four Horsemen of John, the seraph strive to kill all humans and display absolutely no interest in vampires if they transform properly. They speak in archaic language and have no recollection of their human identities.

Kureto Hiragi succeeds in controlling the 5th trumpet for a period of time by making many sacrifices and using the demon Abaddon to possess her.

Some of the angels have abilities loosely related to those listed in Revelation chapters 8 through 9 in the New Testament of the Bible and are referred to by their trumpets.

In the Catastrophe light novels, Mahiru Hīragi brings Guren some documents listing the Seraph of the End subjects. He collects at least four of them before betraying them during the Nagoya Airport experiment in the Vampire Reign manga series. He has been involved in the transformation of at least two of them thus far.

Taboo
According to Ferid Bathory in chapter 46, the experiment "Seraph of the End" is actually an experiment to revive the dead. According to vampire belief, the humans committed a taboo, currently believed to be reviving the dead, which triggers the appearance of an angel of destruction. This is the reason the vampires traveled the world and crushed any organizations working on that experiment. However, the Demon Army has since learned how to control these angels for themselves.

According to Ferid, Guren Ichinose completed the experiment and triggered the Apocalypse when he revived his dead friends, Shinya Hīragi, Mito Jujo, Norito Goshi, Shigure Yukimi, and Sayuri Hanayori. This experiment caused the virus that killed off most of the adult population. The five revived individuals appear to have no knowledge of dying and have continued to age and grow since then. At first it was uncertain whether Ferid was telling the truth or not until chapter 47, which confirms Guren's act.

Abilities
So far, only two full Seraphs have made an appearance in the story. According to the manga, the abilities of each Seraph is different as they are based on the number of their Trumpet. Yu is shown to have heightened physical abilities and the power to turn his enemies into salt, while Mirai is able to spawn Horsemen to attack enemies at her bidding.

Seraphs are shown to be able to heal their hosts and keep them alive despite fatal wounds, such as Mirai being cured of the Apocalypse Virus, and Yu being kept alive after he took three pills, despite all of his internal organs being ruptured already.

Appearance
The appearances of the seraphs in their transformed states vary tremendously, but they all appear to have a wing or wings so far. It is unclear if this is related to their suitability to the experimentation, what proportion of their body is considered seraph, or which type of experimentation has been performed on them.

So far, the only completely awakened seraphs that have appeared in the story are Mirai Kimizuki and Yūichirō Amane. Mirai, the 5th trumpet, has two giant pairs of feathered wings from her back with a giant trumpet floating beneath her. The curse marks on her skin from the Apocalypse Virus disappear as well. In the anime, the opposite happens and the number of markings increase despite the fact the virus has no reason to effect an angel. When Abaddon possess her, the demon manifests in a giant dark figure with many wings behind her and is partially formless. Yu, the 2nd trumpet, has dark sclera and a single pair of irregular black wings once he completely transforms. Although Mirai's wings are bird-like and have feathers, Yu's wings are not bird-like and do not have feathers, as his demon is apparently wrestling control with the angel.

In a flashback, Mika recalls an undernourished seraph child held in a fluid-filled tank with a mask on the face to supply air. The child had feathered wings for arms.

Trumpets of the Apocalypse
NOTE: There are seven trumpets listed here because the Bible lists seven trumpets. The actual number of trumpets in Seraph of the End has yet to be revealed.

1st Trumpet
No information.

2nd Trumpet
By using a certain drug, Guren unleashes the seraph characteristics within Yūichirō Hyakuya for a few minutes during the battle at Shinjuku. When the drug takes affect, Yu screams and loses his mind as he undergoes a painful transformation. His left eye turns dark and bleeds while a massive black wing-like structure sprouts from his upper right shoulder. Although extremely powerful, he goes berserk and attempts to kill any human nearby. He displays no interest in vampires and recognizes no one.

After ingesting three of the standard Japanese Imperial Demon Army supplements in chapter 33, Yu's internal organs rupture, including his heart. However, the power of the angels prevents Yu from dying. Asuramaru advises him that angels can be far nastier than demons. After this event, Yu loses more of his humanity and is implied to become proportionally more seraph in the process.

During the battle at the airport in Nagoya, Yu becomes desperate after Guren becomes possessed and Mirai transforms into the fifth trumpet to purge humanity. After fainting mid-sentence from his severe injuries Guren gives him, Yu take the trumpet within his mind and disregards Asuramaru's warning that this will erase the remainder of his humanity. Screaming, he sprouts two irregular black wings and is surrounded by a pillar of fire upon his transformation. Both of his sclera are dark. He flies freely in this form while cursing the tainted humans and threatening to turn them into "pillars of salt." He easily summons and manipulates vast quantities of salt at will; for example, in the anime he was seen transforming a large volume salt into a spear. After appearing, he attacks the demon Abaddon and disrupts its manifestation.

One Demon Army soldier refers to the second trumpet as the "King of Salt." Once the angel turns his attention to the humans, Asuramaru convinces Yu to become a full demon while Guren encourages the action from below. Horns appear, and Yu uses Asuramaru's blade to stab himself through the chest after he screams about saving his family.

Three months later, he remains a demon.

3rd Trumpet
No information.

4th Trumpet
No information.

5th Trumpet
On the way to Nagoya, Kureto Hīragi has Mirai Kimizuki injected with drugs to force her to transform. She screams and begs for death until two pairs of white feathered wings sprout from her back.

As the story progresses on, it is revealed that Kureto is planning to control an angel, which no one has ever successfully done before. According to Mahiru (who's possessing Guren at the moment), "blood is needed to control the angel." During the Nagoya Airport experiment, Kureto and Guren/Mahiru use the blood of humans, vampires, and demons to bind her and sacrifice many humans and vampires to control her after using Abaddon to possess her. This appears to be successful, but the 2nd trumpet awakens and destroys Abaddon's manifestation.

Three months later, Mirai is still under Kureto's control as she is used to destroy Sanguinem, and then has her attack Shibuya and aid him with Abaddon in defeating Tenri Hīragi. Mirai ends up with a single pair of wings with the appearance of a mysterious, angelic looking being.

6th Trumpet

7th Trumpet
