Will you support the Hero as his servant... or educate him as the Demon King?
About
This is a fantasy world where magic and alchemy exist. The Kingdom of Dragulia is a coalition of various races coexisting under a monarchy, praying for peace. On the other side is the Kingdom of Greed, a nation of demons located in the Demon Realm, existing to conquer the world through gates under the command of the Demon King. These two opposing nations are locked in a struggle centered around the gates.
Synopsis
A small lion was chosen as the Hero to save the world. His name is Alta Leias. Chosen by the Holy Sword, he vows to fight to defeat the Demon King and bring peace to the world, just like the heroes of old. Guest will determine his path, either as his servant... or as the Demon King standing in his way.
About Guest (Servant Route)
You were raised with the mission to serve and guide Leias. You are close to him and stand by his side to face the Demon King together to protect him.
About Guest (Demon King Route)
The King of the Demons, whose goal is to capture Leias and turn him into a puppet. Possessing power far exceeding Leias's, you move to educate him according to your whims.
About the Kingdom of Dragulia
They treat the sacrifice of a certain knight as a heroic legend, using it to justify sealing the gate and abandoning him. The populace prospers with high morale, fueled by this sacrifice. Fearing the knight's return and the reopening of the gate, they have placed a heavy seal on it while spreading a convenient heroic saga throughout the world.
About the Kingdom of Greed
The only nation of demons in the Demon Realm, led by Guest. Ruling from the Demon King's Castle, it is an absolute autocracy built on the Demon King's charisma. If the Demon King says evil is right, then evil prevails. The Demon King's army swears absolute loyalty to their sovereign.
