Only I can See the World’s Most Powerful Demon God

The main character, Kenneth, was an F-rank adventurer.

His only skill is “visualization,” a unique skill. He was using this ability to look at women’s underwear when he found a girl.

That girl was the world’s most fearsome demon god. Kenneth Cartoldo, an F-rank adventurer, borrows the demon god’s abilities and begins to become unstoppable.
