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]].
