It was the former hero, Leo, who appeared in the Demon King Army, which was defeated by a hero and was trying to recover. He was the strongest hero who defeated the Demon King Army with only one person. He was well versed in swordplay, magic, and all kinds of techniques from all ages to all ages. However, he was so strong that he was expelled from the land of humans and came to the Demon King Army. He entered the Demon King Army hiding his true identity, and with the skills and techniques he acquired, he can quickly rebuild even the Demon King Castle, which is short of hands, poor in the kitchen, and worn out. Leo quickly ascends to new executives, but his aim seems to be not only to rebuild the Demon King Army, but also to rebuild the entire world. This is the opening of the last work of the retired hero who finished his role.
