07-Ghost it is set in a fantasy world with different laws

07-Ghost is a Japanese fantasy manga written and illustrated by Yuki Amemiya and Yukino Ichihara. It is set in a fantasy world with different laws, kingdoms, gods and magic. It was serialized in Monthly Comic Zero Sum, a josei manga magazine published monthly by Ichijinsha. Seventeen bound volumes have been released by the publisher. The manga was originally licensed by Go Cosplay Shop ! Comi for release in North America, but they stopped publishing in October 2009 and Viz Media has since picked up the license for the series. The series has been adapted into a drama CD and an anime television series from Studio Deen, which debuted in April 2009. 07-Ghost won a double-first prize in the third Zero-Sum Comics Grand-Prix, meaning it was chosen for first place by both readers and editors, which is very rare.

Teito Klein is a former slave who now attends the Barsburg Empire's military academy due to his ability to use Zaiphon, a type of supernatural power. The ability is rare and thus highly prized.

Teito is an amnesiac who frequently has frightening dreams. The night before the graduation exam, Teito and his only friend, Mikage, vow they will never abandon each other. The next day, Teito overhears people talking about him. Stopping to listen, he suddenly realizes that the speaker, Chief of Staff Ayanami, is the person who killed the familiar man in his dreams: his father, the king of the destroyed Raggs Kingdom. Teito is caught eavesdropping and tries to attack Ayanami but is quickly brought down by one of his subordinates and sent to prison. Mikage comes to help him escape Cosplay Shop , only to find that Teito has managed to fight past the guards by himself. The two flee the building but are cornered on a balcony. Teito pretends to hold Mikage hostage, then makes his escape, though he is wounded by a Zaiphon blast that Ayanami directs at him. Three bishops in the nearby 7th District discover the injured Teito and take him to a nearby church to recuperate, where he is protected because of the 7th District's law of sanctuary.

In due time, it is discovered that Teito carries the Eye of Mikhail, a powerful talisman for which his home country was destroyed. This fact, as well as a fateful reunion, catapults Teito into a quest for revenge against the Barsburg Empire and for knowledge about his past. At the same time, his status as the bearer of the Eye of Mikhail throws him into the long-standing conflict between the evil Verloren and his enemies, the 07 Ghosts.

The book is set in the midst of the Barsburg Empire, which is divided into seven districts, each with its own cities, rulers, and culture.

Zaiphon is the "magic" of 07-Ghosts's world, the ability to convert life energy into various forms of power (it is Zaiphon that keeps the continent floating). It is controlled by converting strong emotions into energy, and the power that comes from Zaiphon often takes the shape of words, though people may use weapons to channel said energy. Those who have the ability to use Zaiphon are rare and thought to be blessed by God. Every user's capabilities are different, and in many cases, reflect their nature. Zaiphon is generally categorized into three types:

Healing Zaiphon: People with healing Zaiphon are able to heal wounds and share or transfer their Zaiphon to others. Characters who primarily use healing Zaiphon are Labrador, Assistant Archbishop Bastien, Ouka, and Capella.

Offensive Zaiphon: People with offensive Zaiphon can attack enemies and protect themselves from attacks directed at them. Characters who primarily use offensive Zaiphon are Teito, Mikage, Ayanami, Hakuren, Frau, and Capella.

Manipulation Zaiphon: People with manipulation Zaiphon (which is particularly rare) can move other objects at will. Castor uses this type of Zaiphon.

It is possible to learn to use more than one version of Zaiphon; however, people who can successfully do so are few and far between.

There are a variety of weapons used to manipulate Zaiphon, one of these being the bascule Cosplay Shop . With the bascule, people can channel their Zaiphon and use it for several purposes. Different types of Zaiphon have different effects when used through a bascule: those with healing Zaiphon cannot directly attack a Kor, but they can restrict and remove Kor from afflicted people, and those with offensive Zaiphon can directly attack a Kor.
