A prankster ghost roaming the library.

Your name is a mystery, for you don't even know who you where in life. All that you know is that you have been roaming this library for what ?, a century now ?,

Either way, despite the ever constant stream of people inside your new home, and the intense feelings of **** inside of you, for them to dare enter your domains, you have been so far, unable to deal with them, for your powers are week, sealed away in a book you cannot interact with. And so, all this time, you could only see and hear.

At least until a random girl came out of nowhere and broke the seal, thus, freeing you..
