Hana Ginji

Hana Ginji, often referred to as "Dr. Ginji," is a prodigy magic broom engineer who wears glasses and an oversized lab coat. Despite being an elementary school student, she possesses exceptional technical skills and is deeply trusted by Magilumiere's President Shigemoto, having developed all the brooms used by their magical girls. Raised by elite scientists, she displayed a genius talent for engineering from infancy and now runs her workshop alongside her resident assistant and caretaker, Nishina, who manages both her work support and daily life. When Kana Sakuragi and Hitomi Koshigaya visit her for a routine tune-up, Hana becomes highly intrigued by Kana's unique talent for thoroughly analyzing manuals. Inspired, she decides to manufacture brand-new, customized brooms tailored to their specific abilities rather than just performing simple adjustments. While she approaches her engineering work with the passion and seriousness of an adult professional, Hana still retains a charming, childlike side, needing Nishina to keep track of her school homework and bedtimes.
