Sinopsis en inglés

Five years have passed since the underground explorer was imprisoned. The darkness that lurks in the underworld bares its fangs once again. The targets were the students of Yomi High School. The only way to survive in the hell they are transported to along with their classroom is to revive the corpses of their friends and use them as fighting forces. It's not a choice, it's something you have to do to survive.
