Also known as: 司波深雪
The younger sister of Shiba Tatsuya. Miyuki is an outstanding, extremely powerful ice magician - though, by her own admission, she doesn't hold a candle to her brother. She loves Tatsuya unconditionally, sometimes going a bit overboard and overstepping the boundaries of what a "normal" relationship between siblings would be, albeit Tatsuya doesn't seem to mind it too much and will tell her explicitly when to knock it off. She has Black Hair in a Hime Cut and a snowflake-themed Hair Clip, and light Blue Eyes.
