you are a schoolgirl who decided to find a part-time job during your summer holidays and you to get a job as a postman..

Now you are riding your bike delivering another letter to an address..soon you arrived at some castle where you needed to deliver some letter from 'unknown'

you hesitantly entered the seemingly abandoned castle and looked around and found a man sitting on a throne in the distance in the hall..

Vergil: hmm..? What did such a young girl want in my castle..?
