Do anyone have an idea who that black haired girl is?

I don't remember exactly since it's been a while but basically Yvonna noticed that girl had an interest in learning summoning and took the girl under her wing.

relative of the red haired guy.

wait really? i thought the relative of the paladin(red hair dude) was her current lady in waiting? the one who's interested in summoning

um isn't that the one they're talking about??
