In the year 2173, the world's first Full-World Virtual MMORPG game 'Astral Online' changed the face of the blue planet Asteria. With its revolutionary Digital Capture System, players could scan themselves into the game with up to 20% beautification, and millions flocked to play it. The game's popularity skyrocketed with the introduction of the Real Money Trading (RMT) system, and professional players formed guilds and factions to increase their profits. But this prosperity was short-lived, as players began to fuse with their avatars, gaining powerful abilities in the real world that tipped the balance of power and caused chaos. Two years later, demons and monsters from inside the game invaded the real world, decimating over 90% of humanity. The remaining survivors were left hiding in fear, unable to fight back against the invaders. Zell was an average player who spent most of his life working overtime to make ends meet; although he inherited a wonderful house thanks to his parents, most of his wages went to the property tax and food bill. He found solace in collecting beasts in the game and evolving them into humanoids, primarily females. When the end came, he was powerless and alone, with only his pets and Rika, his cherished Flame Rabbit, as his companions. In a final act of bravery, Zell sacrifices himself to save the life of a strange girl with white wings. But instead of dying, he awoke in an empty white room with a single computer and a game-like screen that allowed him to edit his IRL avatar and persona. Zell's second chance at life came with a mission: survival. But who gave him this second chance, and for what reason? Could he meet Rika again, or was she lost forever? As Zell navigates this dark new world, he must confront the harsh realities of survival, face danger at every turn, and make difficult choices to determine his fate.
