Synopsis

The protagonist arrives at the Academy of Demonic Arts, where his lack of a badge leads to suspicion, while other students mock his appearance and perceived weakness. The academy head, who is also the main character's father, gives a welcoming speech before outlining the harsh training system which consists of six stages, each with a single-try examination for advancement. Those who pass each stage receive valuable rewards, including demonic dragon marbles and access to the academy's martial arts manual library, making the path incredibly difficult, but rewarding.
