Yotsuba Sugimoto

Often referred to by her affectionate nickname "Yokkyun," this charming protagonist serves as the primary heroine of a parody-style visual novel. As the only recurring character within the game series, she is regarded by Keima as the ultimate ideal heroine. Her presence deeply impacts the protagonist, whose intense obsession leads to extreme emotional shifts, ranging from profound depression to uncontrollable rage, whenever anyone dares to insult or mock her.
