Ngl I was hoping that the next arc would have her maturing after Undine's death and ultimately getting a contract with the ice spirit and it would be this whole symbolic thing since ice is like a "refined" form of water thus proving her growth.
It seems like she hasn't shown much character development since Undine isn't dead anymore but we'll see.
I bookmarked this at chapter 23 since I couldn't stand the tension and 46 chapters later nothing has changed. It's just endless repetition of adventure-pinning-adventure. Does she even address that he tried to get rid of her and essentially put her in hell?
