What kind of name?

"WHAT?!--Here?...Are you sure?" He nodded and continued," There was a war in Tatarus....And the demons were divided into two factions.....Those who wanted Bael as King,and those who still supported me. Because of the Rift's power--He was able to seal away an immense amount of my power-- And he was able to conquer my subjects as well. My most trusted general was able to send me to the gates of Tatarus and she used her abilities to send me here. Before she sent me here--she told me that she was sending me somewhere--a place where I'd find the final Rift and I'd have to use it to get my powers back and return back to Tatarus and take the throne from-HIM....." Junichiro couldn't believe his ears-"B-But are you sure- maybe she mixed it up-" "She doesn't make mistakes-trust me-if she sent me here,that means the Rift is here." "But why can't you return?" "I don't have enough power to travel through "The Chasm" and besides--even if I did make it-Bael would be way stronger than me,I wouldn't able to beat him" But you were able to stop time, you can definitely-!!" "Don't you understand!? I'm not strong enough. Look I just need to live here as a human for a bit-and look around until I find the Rift and then I will leave and even erase your memory of me, but for now- You have to show me everything about this city and help me find the Rift."

Junichiro looked at him and sighed."Fine---but I work so I can't be with you all the time." "What?-- fine -- I'll find something to do-" "And you probably need a name-you can't go around proclaiming to be some demon king.....What kind of name should I give you??", Junichiro said, looking at him with a wondering gaze....
