Aoi is a new teacher who has been transported to another world.

Aoi is picked up by Owen, an elf, and as they live together, Aoi masters more and more of Owen's magic and even surpasses him. In order to refine her magic further, she is assigned to teach at the Fiddich Academy, a school of magic!

Aoi starts her teaching career showcasing overwhelming magical abilities, and she is not daunted by the aristocratic troublemakers who dominate the academy.
However, her abilities have become the talk of the school...

Aoi's life as a new teacher at the academy begins with a tumultuous start...!

A man was reincarnated as Van, a boy of noble birth, who grew up to become a child prodigy through hard work. But when it was discovered that he possessed "production magic," he was immediately relegated to a remote village. However, his magic, which was called useless, turned out to be truly extraordinary, capable of producing anything as long as he had the right ingredients! With the knowledge from his previous life and the overpowered magic, the small, poor village will grow to become into a great city.

An angel made a mistake, resulting in Shiihara Daiki’s death. In order to hide the mistake, he was then sent to a different world. The angel will grant him one wish as a payment for keeping it a secret. Daiki asked for a Heavenly Castle floating in the sky without hesitation.

Suddenly a floating castle appeared in the new world, which causes confusion amongst the people. They attempt to contact Daiki in various ways. A country tries to steal it by force, while another seeks to befriend him. What in the world will Daiki do?
