Nezumi Royale

Nishibe is a timid and perpetually hesitant student who arrives on an island under the impression that he is simply participating in a routine school excursion. However, the seemingly innocent trip quickly unravels into a harrowing nightmare when the students discover they have been thrust into a ruthless survival game. The rules are unforgiving: a rescue boat will arrive in exactly twenty-eight days, but it only has room for five survivors. Trapped in this isolated environment with dwindling hope, Nishibe must confront his own deep-seated insecurities and indecisiveness if he wishes to see another day. The stakes escalate dramatically as the true nature of the island's threat reveals itself, forcing every participant into a desperate struggle where trust is a liability and hesitation can be fatal. As the countdown begins, the students find themselves hunted by an unexpected menace—a horde of adorable yet lethally dangerous mice that serve as the executioners of this twisted contest. To endure the next four weeks, Nishibe will have to shed his paralyzing doubt and fight for his life in a deadly spectacle where innocence masks absolute peril.
