As a Wrong Character in a Sorcerer World

After dying in laboratory tests, Klaus transmigrated to a Sorcerer World, in a strange and peculiar character whose existence is an enigma.

He knew this world, for it was the world of the novel one of his students wrote. He also knew the character because he created it. But it was a discarded character; it never appeared in the novel.

How could he have transmigrated in it?

Reality hit him soon after when he was sent to cross through the first test that every sorcerer must pass to awaken his abilities.

There, he will have to fight against powerful monsters, which they call Curses, and against other Sorcerers, all to try to enter the select group of Sorcerers and discover the secrets that await in this world, his arrival, and his existence.
