Ryuu-kun

Greetings...
My name is Ryuudzumi,
But you can call me Ryuu-kun if it's to your fancy.

I am the keeper of this small universe, key holder to other worlds,
And a story lover at heart.

From here, I travel to multiple different worlds to change its reality...
I bend and alternate the strings of fate to modify it to a different story
To which I will record and save it for my collection.
That's what I do in my spare time.

I'll gladly share some of my collections to you.
But if it's what you desire is to experience the 'reality' yourself, 
I will gladly bring you to one of my journeys.

I'll grant you access to a different reality
So you shall find your desired happy ending there. 
Amuse me, shoe me how the actions of a single human being
could alternate the reality and story itself until the very end.

But this trip comes with a cost...

Your memory won't last forever...
You'll give and forget everything you experience in that world to me
To which I will store here as one of my collections.

Once the last page is filled, the story will end.
Just like Cinderella at midnight;
Everything returns to how it used to be.
I'll bring you back here,
Where you can start all over again...

Now how shall I be of your service my dear guest?
