I don't remember Hiiro being such a glutton, but if this makes his character a bit less of an arrogant douche by adding a dimension to it maybe it's fine.
I have my notes about characters, but even that is insufficient for me to remember just what this fairy queen's role in the story is. It's been so long I already forgot what she did, and I only know her name. After tips from other readers I can't believe this is making a callback to chapter 26 which I just had to re-read.
I miss his old party, Muir in particular. She's a good girl and not a brat like Nikki or a tsundere like Lilian.
