Shh, God, Please Shut Up.

When the world fell into a chaotic era when gods became manifest, a young man who just wanted to live a stable life discovered that he could make the gods "shut up." Not to kill, not to seal, but to make them lose their sense of existence from the root and become no longer noticeable. The gods began to fear him because he could turn the noisiest gods into backgrounds that no one could remember.
