Ultimate user in fantasy world

Waking up with zero memories can be hard, waking up in a strange place with zero memories seems even harder;

"Oi, get up!"

The first words that they hear when they wake. Well - at least they generated in the middle of a town.

This system has a thing for being mischievous. And the new user is proof of that. Does fate really exist? Luck? How else would you explain finding an ultimate object completely at random? What does it mean to be the ultimate in a world were there are dragons and legends and gods?
