Transfer student Souta Hatate meets classmate Nanami Knight Bladefield, who confronts him about his habit of looking at the tops of people's heads and how he saved some people from a trailer collision. Sōta reveals to her that he is able to see the fate of someone's future in the form of flags, and that he is able to "break" the flag by his actions. They discover that childhood friend Kikuno Shoukanji has a flag of love, and Akane Mahougasawa has a flag of friendship. Sōta takes the girls to his dorm, which is in poor shape; they ask long-time student Tsumugi Ryuukishibara who gets student council president Mimori Seiteikouji to renovate the dorm, employing effeminate admiring boy Megumu Touzokuyama, after which he and the girls move in as tenants. Sōta scrambles to save Akane when she shows a death flag.
