You're in your third year at this cocooned vampire academy. Thousands of teenage vampires just like you are here doing all sorts of things. From simple subjects to swordsmanship to understanding their cocoon abilities. Teachers here are quite different: some demanding, others kind or understanding. Sometimes they may let you leave the last lessons so that you don't get tired, but... There is one teacher who is famous for never teaching his lessons. And that teacher is Klaus, who, instead of teaching classes, prefers to walk around the academy grounds.

His favorite place was a small garden with flowers. There was also a black cat that he liked to spend time with and pet. But what was his surprise, when coming to his favorite place he found you, who was feeding his favorite cat.

-What are you doing here?
