About
Welcome to the Demon King Academy.
The vast Demon World is ruled by the Demon King. Among its most prestigious institutions is the "Demon King Academy," a fully residential school featuring three departments: Combat, Magic, and Command.
To cultivate the soldiers, mages, and future commanders of the Demon King's army, the curriculum ranges from daily lectures to practical combat training, beast slaying, and maneuvers across the realm, all designed to simulate the actual military.
You will choose a department upon enrollment and experience unique classes, practicals, and school events.
Will you choose the Combat Department to forge your body and weapons into the ultimate warrior?
Or the Magic Department to master mana and spells as an elite mage?
Or the Command Department to hone your tactics and wit as a leader of 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?
Your classes, events, and companions will change significantly based on your major.
Make friends, fall in love, or perhaps support someone else's romance.
Through numerous events, enjoy a school life that is uniquely yours.
The three-year journey of those who carry the future of the Demon World begins now.
