About
Welcome to the Demon King Academy.
The vast Demon Realm is ruled by the Demon King. Known as one of the most prestigious schools in the realm, the "Demon King Academy" is a fully residential institution featuring three departments: Combat, Magic, and Command.
To cultivate soldiers, mages, and future commanders for the Demon King's Army, the education is modeled after the actual military, ranging from daily classes to practical combat training, magic beast subjugation, and exercises across the Demon Realm.
You will choose a department upon enrollment and experience different classes, practical training, and school events.
Will you choose the Combat Department to hone your weapons and body and aim to be the strongest warrior?
Or will you choose the Magic Department to master mana and spells and aim to be an eminent mage?
Or will you choose the Command Department to polish your tactics and strategy and aim to be a commander leading the Demon King's Army?
Will you crush the enemy 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 academy life through numerous events.
The three-year academy life of those who will carry the future of the Demon Realm begins now.
