While it's possible, I don't think Utsugi is meant to be a gyaru with dyed hair and all. She's blonde with blue eyes, so I think she's more likely a halfie.
I don`t like this girl she is just too much of an annoyance the one that do bad things and said "tehee my bad " fuck off urk and one of the otp i hate in any kind is this kind of otp or friendship
