In Another World With A Teeth System

On a regular day, a classroom of fifteen 16-year-old students and their alcoholic teacher were summoned to another world known as Terra.

They were summoned as Heroes for the great Kingdom of Klyntos with one purpose.

Defeat the four resurrected Demon Princes: Lucifer, Leviathan, Satan, and Belial along with eight generals: Astaroth, Maggot, Asmodee, Beelzebub, Oriens, Paimon, Ariton and Amaymon.

While this challenge seemed impossible for the regular students and their teacher, the incredible powers they all displayed inspired hope in both them and the Kingdom.

All students but one that is. Cadmus had seemingly no powers except his large build, and abnormal growth rate which were present before they had all come to the new world anyway.

Well, that was before his Teeth System Awoke.

This is the story of how Cadmus rises from the ashes to become the strongest 'Hero'.
