Synopsis:

At Myoujou Academy, an exclusive boarding school for girls, a hidden curriculum unfolds within Class Black. Newly transferred Tokaku Azuma discovers the class’s true purpose: they are all assassins participating in a deadly trial. The objective is to eliminate Haru Ichinose, a seemingly innocent classmate, with the promise of fulfilling their heart's desire upon success. However, each student has only one attempt; failure results in expulsion.

Tokaku finds herself conflicted, unable to reconcile the mission with the burgeoning connection she feels towards Haru. As the other students embrace the challenge with ruthless determination, Tokaku chooses a path of protection, determined to shield Haru from the escalating violence consuming their classmates. The series explores themes of loyalty, sacrifice, and the complex nature of desire within an environment where predetermined destinies clash with personal conviction.
