In visual novels, an imaginary flag is defined as an event that serves as a turning point for the whole story. A player triggering the romance flag for a heroine will proceed to her route, or a death flag will signify that a certain character will die afterwards. High school student Souta Hatate can see these flags above a person's head, and has the ability to bring them down to stop certain events from happening. Using this power, he has prevented other people's deaths. But, after a past accident with him as a sole survivor, he ended up believing that only misfortune will befall those who are near him, and has refrained from making friends or having relationships ever since. However, everything starts to change after transferring to a new school. After toppling another death flag, his classmate Nanami Knight Bladefield notices his powers and tries to learn more about him, promising that she will remain at his side no matter what may happen. Thus begins Souta's journey as he meets new friends and acquaintances while uncovering the mysteries of his ability... which might run deeper than what anyone expects. [Written by MAL Rewrite]

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.

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.
