(Apocalypse + supernatural powers + mechs + fantasy + one heroine) This is a war between humanity and monsters! The Starfall Calamity descends! The world is transformed! After the cataclysm, only about half of humanity survives... Just as people begin rebuilding civilization, another disaster strikes! Giant ferocious birds ravage the skies... Monstrous beasts prowl the land... Bloodthirsty schools of fish fill the oceans... As humanity faces this blood-soaked apocalypse, awakened individuals begin to emerge one after another! A battle for survival between heroes and monsters begins! The world enters a new era... On a dark, windy night, the door to a pitch-black room slowly creaked open... A pair of arms, deathly pale in the darkness, slipped quietly inside. A head of black hair followed, squeezed through the doorway. Beneath the waterfall of hair was a pale face whose features were impossible to make out. Then a figure in a white dress slowly floated into the room, the dress stark against the darkness and utterly eerie... The person sleeping in bed didn’t notice the strange figure at all... The figure in the white dress silently approached the bed... “It” looked at the man sleeping face-down and raised one deathly pale arm high... “Smack!” A hard slap landed on the man’s firm backside. The sharp, crisp sound rang through the bedroom... “Ah!” The man let out a howl, sprang out of bed, and quickly switched on the bedside lamp! “Mom! What are you doing?!” “Your sleeping position is wrong! Get up and go back to sleep properly!”
