I'm happy to start brainstorming with what we have and if there needs to be any adjustments we can sort it out later.

Got any ideas so far?

Possibly YC knew MC's mother. They just went down different paths at some point.
YC could be the reason MC joins the guild. Gone for fresh copper rank.

Hmm, I just realized that your character has no name yet. 

Looking at his backstory, I presume he is a runway, trying to escape from a resourceful father who wants to train him to be a sort of domon summoner against his will. 

Jazdia could be a person his mother advised him to look for when things get seriously awry. We can work on the idea that your character's mom and Jazdia were old comrades. Maybe one of them owed the other a favor. 

Another question would be on how elves and mankind's view on half-elf. Jazdia might be someone who doesn't give a damn, but such discrimination against the impure was not at all uncommon, looking at the other IPs.
