Erik Albertani, the seventh prince of the Albertania Kingdom, has always known he would die young. When he finds himself about to get executed in the enemy territory, he hears the voice of deities who promise to grant his wish with his soul as a price.

[[I will grant your wish]]

"I'll give you anything, so please, grant me happiness."

||You have become the summoner of three great deities.||

With the power to reverse the time, the full knowledge of the world, and the unique strength of Ethereal bestowed upon him, he started his journey to live as himself.
