There's not much to say about myself. I don't wish to share many details about my past—or my life in general—but since apparently at least an introduction is required, I will do what I can.

• I'm known as the Gatekeeper, my name is Itsuki. “Gatekeeper” was the appellative I've had between a group of people that shared a similar pattern of names—such as Sniper, Seaman, and so on. I was named the Gatekeeper due to my ability of the same name, and being able to travel through dimensions with my pet, Uraotoko.

For now, that is all. If you want to know more... you can ask me in a less crowded place.
