Dead End Demonics: The First Returner

Eight years ago, an unknown catastrophe called ("Demonization") struck the world. It is a calamity that seals off parts of reality and overwrites them with a nightmare realmif you cannot survive, only a cruel death awaits. In this changed world, Ygo Fushimi lives a quiet, withdrawn life, limiting his outings to commuting between home and work. Gentle, timid, and overly sensitive to others' pain, he is always sleepdeprived and often late, leading his coworkers to mock him as a "clumsy do-gooder" and a "shutin introvert." One day, he is forcibly dragged out to a drinking partyand there, he witnesses the horror of Demonization firsthand. The city is trampled, people scream and cry, his coworkers collapse one after another, and grotesque enemies flood the area as it transforms into a demon realm where survival seems impossible. At that moment, in the midst of despair, Ygo alone grips his weapon as if remembering something long forgottenhinting that he may be a "returner," someone with a hidden past connection to this nightmare and the power to fight back.
