The noble boy, Elt, was neglected because of his talent for plant magic, which was not suitable for combat. However, one day, Elt remembered that his past life was Japanese. He also noticed that this world was very similar to the game world he had mastered in his past life.

Although his plant magic talent was not recognized by the nobles, it was perfect for developing his territory. Elt received an uninhabited territory and decided to develop it. Combining knowledge from his past life and plant magic, the number of his subjects kept increasing, and Elt rose to become a great noble.
