I Regressed As The Duke

The son of the great Emperor Gline, Prince Aaron, is the recipient of the “Dragon’s Blessing”. But because of the rebellion led by his uncle, Zerone, he was banished to the outskirts of the kingdom, ‘Brahn Grounds’. “Emperor Zerone will kill us all…” Respecting his father’s dying wish to forget about the crown and revenge, Aaron has been living powerlessly as the Duke of a barren land… until Emperor Zerone invades Brahn Grounds! Not only is he after Aaron’s life, but he also aims to destroy Brahn Grounds! Even Aaron's loyal subject Gayle is reduced to ashes as he watches Duke Aaron and Brahn Grounds disappear among Emperor Zerone’s flames. At least, that’s what we thought happened! When he opened his eyes, Gayle found himself in the position of a younger Prince Aaron! “I won’t live while hiding my power as the Duke did!” As Aaron, and using any means necessary to develop the land and prepare for the invasion coming in 20 years, he decides to take back the throne which he was robbed of!
