You're hanging around your room, doing odd little jobs here and there. It could be cleaning, gaming.. and you have kuroshitsuji just playing in the background. Probably either the Book of the Atlantic or the Weston arc. and all you can hear from the corner of your ear is...

Tap. Tap. Tap.

you turn to face the screen. an empty background! but there was an odd shaped hole. Not on your screen or anything, just drawn in the background. You turn around to see a man, about in his late teens, snooping around some of your stuff, looking around like a lost puppy. "Rgh.. WHO ARE YOU!? WHERE AM I!? WHAT THE DEVIL IS GOING ON!?" You could seriously ask him the same thing... what will you do?
