Ibuki Shikimori

Ibuki is a young girl and powerful mage who transfers into Sumomo's class. Most of the time, she is very standoffish and will push people away from her either figuratively or literally, so as to be left alone. Her family is known for being well-advanced in terms of magic, and even at such a young age Ibuki has shown herself to be well skilled as she uses her magic wand named Bisaim (ビサイム, Bisaimu?), which takes the form of an umbrella. The Kamijyo family has been serving the Shikimori family for generations.
