Story of Anime

is a 12-year old Japanese boy who lives near Tokyo. Never having met his parents, he lives an ordinary life with his adoptive grandfather. His grandfather had taught him a series of strange hand movements, which Riku did not know the purpose of until the day his grandfather is attacked near his shrine. But it is not an ordinary attacker. The attacker is a , strange monsters with human owners. Riku comes to the scene and that's where he first gets in contact with his , the device he uses to call and make a with , his Shikigami and, from that day on, best friend. The Shikigami needs, for special attacks, a special series of , one of which happens to be the strange hand movements Riku's grandfather always taught him. As Riku's grandfather decides to leave the house for a journey, the 10-year old boy and the 10-year old girl rent rooms in Riku's house. The 17-year old man, Masaomi, who teaches Riku the secrets of Onmyoudou (such as the use of Toujinfu, for example), drops by eventually. The three of them have 'contracts' with Shikigami. The main events of Onmyou Taisenki anime are related to the menace of the , a powerful Japanese financial group related to the Onmyoudou; attempting to open the four ; and freeing , a boy who was born with the power to control , and had been imprisoned for thousands of years.

The Shikigami

For specific information, refer to the list of Shikigami.

Onmyō Taisenki shows monsters called Shikigami. There are 24 families of Shikigami (three per family for a total of 72) to represent each Solar term. These monsters are extremely powerful, and their are activated when their owners use certain sequences of In. Every Shikigami has its own In sequences and some have special weapons, which are also activated by the In. Every Shikigami has its own name and a class/family. For example, Byakko no Kogenta's name means , one of the four Japanese great Gods; the other three are , , representing the family of turtle-type shikigami), and family. Class names are usually named after gods and flowers.

The Shikigami can transform into a , which is a giant and extremely powerful form where they usually go berserk. Although Nazuna says that a true Daikōjin occurs when Mind-Technique-Body are together, Riku has been able to summon one when he is highly desperate and emotional (usually when Kogenta is about to be killed). Shikigami can also transform into Daikoujin form by forcing a Tōjin stone into a Shikigami, as Isou does to his Shikigami Fuji in Episode #20 (or by inserting a special chip made from the Tōjin stones into the drive). However, these methods only produce a confused and pained Daikōjin and causes the Drive to sprout coils that will eventually kill the Tōjinshi if the Daikoujin is not defeated. In addition, members of the obliterated sect Jin-ryū have been able to change their Shikigami into Daikoujin by using lengthy series of In.

When a Drive is activated for the first time, the Shikigami will appear behind a shoji and asks what the owner desires, and if it is to the Shikigami's liking, it will accept and a contract will be formed. Once the terms of the contract have been fulfilled, the Tōjinshi and Shikigami will part. However, when a contract is broken (Shikigami dies or Tōjinshi tries to break the contract), the Tōjinshi loses all the memories built since when he first contracted with the Shikigami and usually wanders around lost and depressed while the Shikigami is sent to Naraku (underworld, hell). Similar events happen with Riku in Episode 23-24, as he rejects his contract with Kogenta and consequently does not remember people he only met after he formed the contract, but still remembers his childhood friend Momo.

Characters

Ten-Ryuu

The main character of the show, Riku was originally borne in the Heian Era of Japan as Youmei. His mother sent him into the future, where he was taken up by Soutaru Tachibana, to avoid dying in the Chi-Ryuu raid on the Ten-Ryuu shirne. At the start of the series, he's shy, and easily scared. But when he receives the Ten-Ryuu Toujin drive containing Kogenta, Kogenta helps him to become a lot braver and stronger. He has no memory of his time in the Heian era until he goes to Naraku to reunite with Kogenta after losing him by Yuuma and Rangetsu. In Naraku, he sees his memory play in front of him, and learns of his past life. He is the head of the Ten-Ryuu.

The shikigami of Riku Tachibana. Kogenta is a member of the Byakko (White Tiger) family of shikigami (leading many to the conclusion that Riku is Ten-Ryuu's Head). He is typically cocky, arrogant, and quick to anger. At first he can't believe that he's "Stuck with someone as dimwitted" as Riku, but eventually comes to terms with this and tries to improve Riku's character. He is the first Shikigami to become a Daikoujin, but he considers it an unfair advantage because, in his words, "I can't remember how I beat them and by the time I come to, the fights already over." In the finale, Kogenta willingly lets Riku terminate their contract, but it is speculated that the contract still lingers, as Kogenta's spirit is seen over the shrine.

The first real member of the Ten-Ryuu that Riku and Kogenta meet. Teru is broke, and nearly always in debt to someplace (A Hot Spring Hotel, a Beach Bar, and others). He is always happy to receive free food (on account of him being unable to buy his own), and always travels as "Training" as he calls it, normally leaving as soon as someone tells him the rent for wherever he is staying. He even develops a crush on Nazuna, who shows him the literal meaning of "crush". He consides Souma a rival (as both love Nazuna), and only enters the Fukumaden as leader of the Youkai Extermination Squad formed by Chi-Ryuu.

Story of Manga

The Onmyou Taisenki manga does not tell the same history as the anime. The story happens years before the events in the anime. The main character, Yakumo (who also appears on the anime, as a teenager) is the son of Monju, the chief priest of the Taihaku Temple, in Kyoto. Yakumo also trains the In, with a baseball ball. In this temple, a , and Monju's former teacher, Mahoroba, is imprisoned. The problems start when Mahoroba escapes, gains power, and transforms Monju into stone. Yakumo is called by a Zero Drive, which was one of the treasures of the temple. This Zero Drive handles Byakko no Kogenta. The story of the manga is about Yakumo's first steps with a Shikigami, training with Idzuna (Taihaku Temple's shrine maiden) and seeking Mahoroba through various Japanese historical dates. Famous Japanese historical characters such as Oda Nobunaga can be seen on the manga. The story is cited by Kogenta around episode 35 in the anime. However, not many details are given.

Factual differences with the anime

Even when the story of the Manga and Anime appears to be in the same universe there are some factual differences in the world of the anime and manga. In the manga the names of the shikigamis are created by their Toujinshi at the time of the contract and in the anime the names of the shikigamis are always the same. For example, in the manga the name of the shikigami that once made a contract with Monju is revealed to be "Byakko no Akatsuki", and then it's revealed that is in fact the same shikigami as "Byakko no Kogenta", and the name Kogenta is the name that Yakumo gave him. In contrast the anime reveals that the name of Byakko no Kogenta has been always the same, as is revealed in the anime when the story of the contract between Byakko no Kogenta and Raihou is told. Also, in the manga, there are no factions between the Toujinshi, and every Toujinshi is independent. Even when in the anime almost every Toujinshi uses a Drive, in the manga almost every Toujinshi uses a Toujinki, with the exception of Yakumo who gets his Zero Drive from the Naraku in the middle of Volume 2 in order to save Kogenta because Yakumo's Toujinki is destroyed, and Tsukuyomi that summons his shikigami with Toujin-fu. It also is revealed in the manga that the Drive is in fact a Toujinki prototype. In the anime when the Toujinshi shikigami is defeated the Toujinshi loses his/her memories as Toujinshi and he/she can no longer be a Toujinshi. In the manga the only consequence of a Shikigami defeat is that the Toujinshi can no longer make a contract with that shikigami.
