Creation follows by destruction. It is the unniversal rule that the world will try to reach the state of nothingness. Then is it natural for everything in existence to accept the fate of destruction eventually? No! They will resist that rule. They will not allow their existence to be erased off like that. They will fight against the force of unniverse trying to eliminate them. The Inter Dimensional Alliance Force (IDAF) is the combined force between all the worlds in existence to fight against the Abyss, the infectious species created by the universe to drive the destruction instinct of all beings. The story follows the path of a man joining the IDAF.       *Author's note: This is actually a side project that I just wrote on a sudden inspriration. I want to see how good this novel is as a clickbait with first chapter. If there are a lot of comments and reviews requesting for continuing this story, I will do it (said shamelessly).
