The Devil's den; a notorious hangout for high school seniors, computer geniuses and competitive gamers. And a home to the most feared hacker between the students. Not the place for an innocent young highschooler to find themselves in. Francy's oldest brother is one to be a regular and he made her swear neither she nor his other siblings would ever under any circumstances come near that place. But when Francy's cat gets into a painting accident, she rushes to her nearest brother for help, straight into the Devil's den. Only instead of her brother, she meets the Devil himself. And just so it happens he has a soft spot for cats.
