Busted! Darklord

In order to leave the countryside, Yú Rénjié, the son of the Darklord, was ordered to enter the highly prestigious Good Faith Academy.
The goal is to obtain a Good Faith Certificate which would relegitimize his demon heritage.
The task is a dangerous one because if he is found out to be part of the demon faith, countless "righteous" knights will kill him on the spot.
On the day of registration, Yú Rénjié was shocked to find that his personal information had been leaked.
In order to hide his identity, he chose to put on women's clothing.
His/her dangerous and hilarious school life is about to begin!
