Loosely based on the novel Romance of the Three Kingdoms, modern day Japan sees a similar struggle for power between different rival schools with the three strongest being; Kyosho Academy led by Sousou Moutoku, Nanyo Academy by Sonsaku Hakufu and Ryuubi Gentoku from Seito High School. Together these three tousei, each with their own mangatama, fight for the honor of becoming ikkitousen and fulfilling their fated destiny through battle and conquest. (Source: ANN)

In Ikkitousen, the Kanto region of Japan is locked in the middle of a turf war between seven different high schools. Among the students of these schools are a select few who are in possession of sacred beads. These magatama harbor the souls of warriors who fought during the Three Kingdoms Era of Chinese history. Not only are these students blessed with abilities that draw from the souls they are tied to, but they are also blessed, or maybe cursed, with the fates of these warriors from the past. One of these students is Hakufu Sonsaku; a young, caring, dim-witted girl who has recently transferred into Nanyo Academy and will be living with her cousin, Koukin Shuyu. Hakufu’s arrival creates an almost immediate sense of tension due to her power as a fighter and the possibility that she may be the one who carries the spirit of the Chinese warlord, Sun Ce. The most powerful fighters at Nanyo, known as “The Big Four” are shaken by her presence and determined to stop Hakufu from achieving the goal given to her by her mother: to conquer those who challenge her and unite the seven schools.

Cool-headed and rational, Koujirou Shindou is a government official and master negotiator with a well-earned reputation. While departing on a business trip, a giant cube materializes and his plane is taken undamaged into the mysterious, indestructible structure. As Japanese authorities attempt to identify the cube's properties and origins, Shindou encounters an otherworldly entity known as Yaha-kui zaShunina, who materializes in the form of a human man. He assures Shindou that the passengers are not in any danger and requests help in negotiations with the human world. Hailing from a higher dimensional universe known as Novo, Yaha-kui zaShunina is able to transfer information between Novo and Shindou's universe through a cube called Kado. Despite having these unfathomable abilities, he does not appear hostile. Instead, he announces that he has come to this world with only one intention: to "advance" humanity—starting with Japan.
