Hero? No, I’m an Ordinary Citizen (Monster)

In the summer when I was 16 years old, I was summoned to another world as a hero.
After that, a psychic, an alchemist, a sage, spirit mage, Demon Lord —being summoned by many other worlds, I repeated a lot of meetings and partings.

As he watched over the summoned heroes from the shadows and under the sun, he complained as he resolved the problems that he was dragged into.
