**Funny school adventure of a monk with a secret mission from Tibet!**
Even the oracle, that locates Dalai Lama’s reincarnation, would not foresee that the troublemaker Dang is taking the mission to find it. However, Dang’s power is yet hidden; his fatal nature explodes chi by sexual impulse and turns him into a monster! Not knowing this, Dang enters Mouhyuk High; following the oracle. But his class is a special class called “Trash”, filled with a bunch of weirdoes, and his biggest enemy, the “Coke Bottle” woman! Can he complete his mission?
