After Eating Mushrooms, I Discovered the Truth About the World

That day, I just took a bite of some mushrooms, but stumbled upon the real world hidden beneath reality: deranged mental patients, bloodthirsty devils, and figures from legend and mythology. A terrifying game like a massacre. Is reality their playground or a place of salvation? What are they really after? What is the truth behind the real world and the world we know? Only by finding my grandmother, who died for no apparent reason, can I find the answer that will bring peace of mind.
