Visual novels feature an essential story element known as imaginary flags. These flags signal a significant change in the plot, be it the start of a romantic relationship or a character's looming death. Souta Hatate is a high school student who has experienced a traumatic event, causing him to see these flags above people's heads. To avoid unwanted outcomes, he withdraws from connecting with others. Yet, when Souta transfers to a new school and prevents a death flag from manifesting, he finds himself on a different path. Nanami Knight Bladefield, a classmate, becomes intrigued by his unique ability and promises to support him, no matter what. As Souta builds new friendships and unravels the full extent of his capabilities, he realizes there's more to his power than he thought.
