The squeaky high pitched voice was there and everything with this one.
One of the anime characters who gets on my nerves is Chiho from The Devil is a Part-Timer!.
She on my nerves for a number of reasons, but mostly because she kept barging on in my Maou x Emi ship.
Chiho was whiny and had a high pitched voice that grated on me.
Yeah, she just bugged me a lot.
