Cthulhu Gonfalon is a story about a man who woke up in another world. After a drink over his loss in a game, Sui Xiong ended up in the middle of the sea. Surprisingly, he now found out he no longer existed in a human shape but in a spirit state without any flesh. In order to survive and find a way to return to Earth, he then searched for a body to accommodate his spirit. After several confrontations with some creatures under the sea, he decided to settle for a jellyfish flesh. This Jellyfish was extraordinarily huge. With its tentacles, it caught others’ spirits to nurture its own power. In this world, Sui Xiong wasn’t only matchlessly powerful but he also had an ability to cast magic. With this gifted ability and combined with his knowledge from the civilized world on Earth, he could help a deceased person resurrect, change a person’s look, and do tons of other crazy things that he didn’t know.

As his journey to discover this world went on, he encountered many bizarre and mystic creatures along the way, who were Gods, Humans, Devil Beasts, Giant Dragons and lots of other undetermined organisms. Some of them might insanely worship him, while others hated him. Some might become his enemies. Some might end up becoming his teammates in the end. From a gamer on Earth to here, he became a God (even he himself could not verify this yet), had his own religion and even a church with a Holy Land to fight for justice.

What kind of world is this? What kind of existences might live in this world? What kind of secret this world owns? Can Sui Xiong return to Earth?

Keep on following the story to find out the answers for those questions.
