Other Info
Like you, he is not from this world. in the v.01.1 update, he disappeared completely after doing his quest (not confirmed if he appeared before doing his quest). It isn't clear how he got to this world, as the Old Wizard says that you're his first summon.

Before starting Experimental Goo quest.
"You aren't from here... kinda like me. I'm doing experiments to see what this world is like. Please summon a Green Slime from me using souls."

"Enemies in this world sometimes drop souls. If you get 5 souls, you can summon them as a hero."

After summoning a Green Slime for him.
"I see! So that's how the summoning process works. I'm going to join you on your adventure so I can learn more about how this world works."
