Age: Unknown, but definitely over 70
Birthplace: Mount Katsuragi, Nara
Position: Ninjutsu Academy Headmaster
Role: Class President Committee advisor
The Ninjutsu Academy's headmaster is best known as an eccentric genius—formidable in his younger days as a ninja, though these days he runs the school almost entirely on impulse. Whatever idea strikes him tends to become school policy, which the students and staff have learned to endure with varying degrees of patience. He loves the spotlight and has made a habit of giving out personal figurines and portraits of himself as prizes at school events, which tells you pretty much everything you need to know about his priorities.
Over the decades he's built an enormous network of allies and enemies alike. He's such a magnet for trouble that assassination attempts on him are basically a regular occurrence. In the anime, he's depicted with a granddaughter named Shige who studies in the kunoichi class, and he's rarely seen without his ninja dog Hemu Hemu tagging along as his faithful companion.
