07-Ghost whereupon the stone appears in the host's hand

The Eyes of Mikhail and Raphael are a set of holy stones that can be embedded into the body, allowing the Archangels Mikhail and Raphael to descend into a host's body for a limited time. They are undetectable until they possess their host's body, whereupon the stone appears in the host's hand, the host's eye color changes, and they become able to wield godlike powers with Zaiphon. Before the storyline of "07-Ghost," the royal family of the Kingdom of Raggs held the Eye of Mikhail and the Barsburg Empire held the Eye of Raphael. A pact was established between both countries never to seize the other Eye; however 07-Ghost
, the Barsburg Empire broke this pact ten years prior to the storyline.

The Eyes' full usages are unknown; however, thus far, the Eye of Mikhail has been used to seal Verloren's original body in Pandora's Box, and the Eye of Raphael has been said to be able to reincarnate Verloren's soul in human bodies.

The overall style for 07-Ghost fits into the fantasy manga genre. Although the plot is serious, there is a lot of comic relief, giving the story a more lighthearted tone. The characters are all complex, varied and entertaining, and the story is extremely emotional. It is often disputed as to whether it is a shōnen or shōjo manga, since it has qualities that appeal to both demographics.

"Character designs tend towards the bishōnen type. Even within our circle of bishops, [there's] the naughty rebel, the eyeglass character, and the lolishouta type. Despite the angst filled and mysterious storyline, the manga also includes quite a bit of humor from Teito's and Mikage's horseplay and our three bishops' quirks, and chibis and deformed expressions are used for these scenes Cosplay Costumes

The protagonist of the story. His real name is revealed to be Wahrheit (German for truth) Tiashe Raggs, son of Weldeschtein Krom Raggs, and he is the prince of the former Raggs Kingdom. However, after being entrusted with the Eye of Mikhail during the invasion by the Barsburg Empire, his identity was hidden and he was raised by his uncle, Fea Kreuz, as a church orphan. Upon the death of Kreuz, he was made into a combat slave (Sklave in german), but eventually entered the Barsburg military academy and became known as a star pupil. He is a clever student and very talented, making him one of the best students despite other students' mockery.

At the beginning of the story, Teito is a cold and serious student due to his only memories being those of a combat slave whose only purpose was to kill criminals. He is initially cold to Mikage as well, although the two eventually become good friends. Strangely, according to the academy chairman, Miroku, Teito's greatest weakness is his compassion, despite all the hardships he has gone through.

Teito is very skilled with the Bascules, even exceeding the Zaiphon limit twice for it during training.[3] He is very agile and an excellent runner after having trained with Castor's puppets, and manages to get through the examinations on his first try with Hakuren and he became Frau's apprentice. His slave number was 2741.

It is hinted by Mikhail that Teito is the best vessel he has ever had. Teito receives extra abilities as the master of the Eye of Mikhail, such as advanced hearing and a sixth sense. More are said to be sleeping within him. He was made the master of the eye of Mikhail due to the pope inserting Verloren into his body. The Eye was used to seal Verloren's body and protect Teito's soul, making him the Pandora's Box.

A perverted Bishop who hides porn in the library(even though it is not allowed for priests to read porn), he saves Teito's life when Teito falls from his hawkzile. He is the member of the 07-Ghosts known as 'Zehel'.[5] He finds Mikage (as a small dragon) for Teito and accidentally becomes Teito's 'Master' when he attempts to remove Teito's promise collar, thereby invoking a blood contract. This collar gives Frau the ability to use three commands on Teito: bind, sleep and pain. For all his teasing, Frau also keeps Teito's spirits up with impromptu pep-talks. His relation with Ayanami is not yet known. Frau is the only Ghost who can wield Verloren's scythe, though how he managed to get this scythe is currently unknown. His catch phrase before every battle is "May God be with you". Frau was ranked second in the latest popularity poll in Monthly Comic Zero Sum.

Another bishop, he convinces Teito to take the examination to enter the priesthood. The training he puts Teito through is vigorous and often involves his 'dolls', life-sized puppets he controls with Zaiphon. He is one of the 07-Ghosts, 'Fest' 100cm wigs
