Movie
Description
Katsuto Juumonji leads the Juumonji family, one of Japan's governing Ten Master Clans. He became head in 2097 following extensive childhood training under his grandfather Juumonji Gai and father Juumonji Kazuki. The family specializes in wide-area defensive magic protecting Japan's capital region, with their influence centered in Kantō and Izu.
Standing approximately 185-186 cm tall with a heavily muscular build, broad shoulders, and dark hair, Katsuto carries an imposing presence marked by dignity and composure. He demonstrates a reserved, no-nonsense personality, speaking only when necessary while upholding strong principles, responsibility, and loyalty to his duties. He treats others without discrimination and expects similar commitment from those around him.
His combat abilities focus on barrier magic, particularly the signature Juumonji technique Phalanx. This move-type defensive magic generates multiple layered barriers that continuously regenerate, functioning both defensively and offensively. These barriers withstand temperatures exceeding 20,000°C, repel physical and magical assaults, and can be deployed aggressively within 400 meters. He also uses Reflector to reverse motion vectors, Psion Wall to create self-reinforcing psion barriers, Spatial Awareness to detect spatial disturbances and assess magical potential, and Neutron Barrier magic for radiation containment.
A defining aspect of his power is Overclocking, a clan-exclusive technique that temporarily boosts his magic calculation area activity beyond natural limits at the cost of shortening his lifespan—a toll that historically caused magic loss in previous family heads through repeated use.
During the events of "The Girl Who Summons the Stars," Katsuto intervened when USNA STARS magicians Ralph Algol and Ralph Hardy Mirphak attacked a research facility on Minamitate Island. He arrived to support Erika Chiba and Leonhard Saijo against these operatives amidst the larger conflict involving the rescue of genetically modified magicians and preventing the Strategic-class magic Meteorite Fall.
Katsuto attended First High School, participating in the Cross-Field Club and later leading the Club Management Group. Alongside Saegusa Mayumi and Watanabe Mari, he formed the school's "Big Three" (Triumvirate) due to his exceptional abilities. He maintains connections to the Tenth Institute, a government facility researching defensive magic, and resides in the Juumonji main house near Tokyo.
His family includes father Kazuki (former clan head), stepmother Keiko, adopted nephew Yuuto, younger brothers Tatsuki and an unnamed middle school sibling, half-sister Alisa, and youngest sister Kazumi.
