Kotori Daiki was suddenly summoned to another world, and although he gained a skill during the transfer, he was told by the summoners, and the King, that he was not useful in battle, so he was kicked out to live in the city until the Heroes who had been summoned to defeated the Demon lord and return home

He’s confused, but he finds relief when he gained a large sum of money through a deal with the prime minister.

That night, a young Goddess appeared before him and gave him power.

Giving him the power to gain skills like how it’s common in this world, and the power to teleport.

The power to easily enhance his skills. It’s to let him enjoy the world.
