Shoujo Shikkaku

Akane is an unassuming student at Hanazono Girls' Middle School who has grown quietly exhausted by her overbearing friends. Beneath her plain exterior, she harbors a dark, silent wish: that the world might simply end. Her life shifts abruptly when a mysterious transfer student arrives in Class C of the third year, setting off a chain of events far beyond anything Akane could have imagined. The following morning, every girl in the class awakens to find themselves trapped inside a desolate version of their school, each bearing a ticking countdown timer. They are thrust into a brutal seven-day battle royale where every student is bound to a specific partner for survival. To Akane's shock, she discovers that her designated partner is none other than the enigmatic new transfer student. As the deadly game ignites with explosive force, long-standing friendships crumble under the weight of desperation. Hope evaporates and sanity is pushed to its absolute limits as the girls are forced to fight for their lives. Bound together in this nightmare, Akane must navigate betrayal, fear, and the grim reality of a contest where only those who endure will see the final day.
