In the depths of the Underworld, Izuku is a lethal assassin desperate to reach Earth for a critical contract. The only way across is through a legendary Grimoire owned by Prince Katsuki. Refusing gold or power, Katsuki offers a different price: for every night Izuku borrows the book, he must spend it in the Prince's bed. What begins as a transactional deal between two dangerous men slowly blurs the line between necessity and desire.

Be Katsuki or Izuku
