>>4324708The problem isn't that her voice is too deep or masculine, it's that she sounds like a jock when she talks. Her voice actress there is Mitsuki Saiga who has a wonderful voice and has voiced some adorable girls and reverse trap characters in the past.
Her voice is irritating there because she tries to go for the high pitch, high energy jock voice instead of something that makes you feel safe and leaves room for gap moe if you tease her into giving you a higher pitched voice. Saiga Mitsuki voices a lot of male shounen characters in general and that seems to be the voice they went with here.
That was way too long for a /c/ thread sorry.
