# Shōnen Onmyōji

Shōnen Onmyōji (少年陰陽師) also known as The Teen Exorcist is a Japanese light novel series written by Mitsuru Yūki and illustrated by Sakura Asagi. The novel is serialized in Kadokawa Shoten's The Beans. The light novel has 56 volumes, including three short stories and a side story. A manga spin-off was serialized in Beans Ace.
There is also a series of drama CDs, a PlayStation 2 game and a manga adaptation that was announced in 2005 and a musical as well. Moreover, it was announced in August 2006 in Newtype that the anime adaptation would be animated by Studio Deen and the character design was to be done by Shinobu Tagashira. It began its broadcast on October 3, 2006.
The anime premiered on Animax Asia under the title Shōnen Onmyoji: The Young Spirit Master. It was aired across its respective networks worldwide, including Hong Kong, Taiwan, and Vietnam, with translations and dubbed versions for English language networks in Southeast Asia, South Asia, and other regions.
The anime was licensed for North American distribution by Geneon Entertainment. However, only three volumes of the series have been released, and have yet to receive a full release due to Geneon's departure from the American market.

## Plot

The protagonist of the series, which is set in the Heian era, is Abe no Masahiro, the grandson of the great onmyōji, Abe no Seimei, who passed his teachings on to his grandson. Unfortunately, Masahiro has lost his sixth sense and with it the ability to see spirits. Masahiro constantly feels overshadowed by his grandfather's fame.
One day, Masahiro meets a fox-like creature which he names Mokkun (もっくん) who shows him his true potential powers after fighting a demon. Mokkun is actually Tōda (騰蛇), who prefers to be called Guren. He is one of the twelve shikigami called the Shinshō (神将), who has pledged his loyalty to Seimei and is helping Masahiro to surpass his grandfather.
Masahiro's dream to surpass his grandfather will not be realized as easily as he hopes. Not only does he have to convince the other Shinshō that he is Seimei's true successor, he must also increase his power in order to stop demons coming from China, the other parts of Japan and the Underworld.
