Who am I? That's not a particularly important question.
In this tiny world, do I exist only here?
This world is far too vast and far too small: vast enough for countless books to form its sky and earth, its mountains and oceans, yet so small that before me there is only one unusual door.
I have no name.
I thought things would go on like this forever.
Until you, with golden hair, so frail, with those lonely eyes... one day pushed open this door.
Now I call myself Gu Men.
Thank you, all of you... for opening "me."
Thus our contract is formed. Gu Men's journey begins here.
"But if you ask why I'm so good at this, all I can say is that I've been through a hundred battles and jumped ship from the Nine Vessels too many times."
P.S. This book's title is abbreviated to "Gu Men." Yes, it's the same as their name.
Volume One, Bloodline: Fengli Ziluobin, ongoing. Volume Two, Nine-Vessel Jump: Persona 5, undecided. Volume Three, FGO: London Fog, undecided. Volume Four, Feeding Tiamat the Holy Grail, undecided...
