10 years ago in the year 2153, the world experienced a crisis never before.   portals started manifesting worldwide, inside those portals were monsters unknown to that of modern science. Because of the looming threats the world's powers banded together and created the Evergarden. A floating island of gigantic proportions with the aim of protecting humanity against interdimensional threats. With the discovery of mana, this is how Daichi, someone who defies this new world's common sense, and his allies protect the world from the interdimensional threats.
