Class 3C was just another high school hierarchy—until the sky went black, the school sealed shut, and a voice from another world made them a deal:

Survive for one year, or kill every Hollow in the building.

Each student awakens a strange new power—called a Spec—including Mikaela, the class punching bag with a mind sharpened by trauma and isolation.

But powers won’t stop the horror.
The undead walk the halls.
Sanity frays.
And the line between classmate and enemy starts to blur.

This isn’t just survival.
It’s entertainment.
And Class 3C is the show.
