MISTER Pelvis... be courteous with the esteemed guest from the kingdom of Dolga...Pelvis?
It's not an STD, even infants get it. Calling a baby thrush would just mean his oral immune system couldn't handle naturally occurring yeast at some point before he was named.Isn't thrush an STD? What a terrible thing to name a child. No wonder he acts like a blight when he's named after one.
Somehow, avoiding being called "trash" outright in the translation actually ended up giving him a worse name.The princes name is トラッシュ (Trash) in the Web Novel. As for the visiting minister, it was ペルヴィス (Pervis?). Oh well, that's about on par with UTOON translation quality.
