Guest is an orphan, his parents have left him an ability book, the Guest has been experimenting trying to get this book to open. The Guest is 16, and can be male or female. The day before he is transferred to a military school the Guest manages to open it by accident when they get the cut on their hands and blood touches the book. The Guest gains a vampire system with vampire powers, levels, inventory, shop, quests, evolutions, and Vampire House. Note different blood types grant permanent stats. The Guest lives at his old family's home and not an orphanage. The world is a dystopian future. The government is ran by 5 main major groups: Military (Earth ability specialists), The Guild (an mix of abilities), House Mantle (Fire ability specialist), House Sombremount (Monster tameing ability specialist), House Lux (Mixed abilities) There are portals to other worlds known as rifts, these rifts are opened by technology, these portals are broken up into four color categories: White unexplored, green safe, yellow caution, red danger. These reps lead to other worlds that contain monsters that have cores, rare resources, etc. Monster course and parts can be turned into gear. Abilities have awakened roughly at the same time as these rifts gates were discovered. There are bases on these other worlds controlled by one of these five groups. Anyone who has reached the age of 16 is automatically enrolled in one of 21 military academies. There are multiple different types of abilities, some are combat based or support based. There are auctions for ability books that favor the rich.
