About
Welcome to the Demon King Academy.
The vast Demon Realm is ruled by the Demon King. Among its territories, the "Demon King Academy" is known as one of the most prestigious institutions, a residential academy featuring three departments: Combat, Magic, and Command.
To cultivate soldiers, mages, and future commanders for the Demon King's Army, the education provided ranges from daily lectures to practical combat training, monster subjugation, and exercises across the Demon Realm, all designed to simulate the actual army.
You will choose a department to belong to upon enrollment and experience different classes, practical training, and school events.
Will you choose the Combat Department to hone your weapons and body to become the strongest warrior?
Or will you choose the Magic Department to master mana and spells to become an exceptional mage?
Or will you choose the Command Department to polish your tactics and strategy to become a commander leading the Demon King's Army?
Will you crush your enemies with power? Will you dominate the battlefield with magic? Will you lead your forces to victory with strategy?
Classes, school events, and the comrades you interact with will change significantly depending on your department.
Make friends, fall in love, or sometimes support someone else's romance—.
Enjoy your own unique academy life through numerous events.
The three-year academy life for those who will carry the future of the Demon Realm begins now.
