A 14-year-old boy. Weapon: Hyoto (throwing knives). Blood type: B. Zodiac: Gemini. Living in the Muromachi period at Ninjutsu Academy, a school dedicated to training students into ninjas over a six-year curriculum. All students live in longhouses within the academy grounds. Saburo is the class president of Class 5-Ro. He possesses extraordinary disguise skills rivaling professional ninjas; rather than hiding to change, he can disguise himself in an instant right before someone's eyes. While he can mimic any face or voice, he cannot hide his physical build. He is also skilled at seeing through others' disguises and applying them to others. Due to his craft, he has keen observational skills and is talented at drawing. He places immense trust in his classmate Raizo Fuwa and usually takes on Raizo's appearance. His hair is a brownish-orange, waist-length ponytail, but this is actually a hairpiece used for his Raizo disguise and is detachable. His face is a highly sophisticated mask that is indistinguishable from a real one. No one has known his true face or original hair color since he enrolled. He is somewhat fickle, mischievous, and moves at his own pace. He is deeply affectionate toward those he lets into his inner circle. He won a martial arts tournament held at the academy, leading to the legend of "The Invincible Saburo Hachiya." Due to his high-level disguise techniques and proven combat prowess, he is hailed as a genius and is considered the most elite among the fifth-years. Because he is fully aware of his own excellence, if he loses to a professional ninja, he doesn't just accept it as "inevitable" but feels genuine frustration at not winning. However, he still falls short of the sixth-year students due to their greater experience and the strict seniority system, leading him to avoid interacting with them whenever possible. As a ninja-in-training, he is still developing. Despite his talent, he has a tendency to prioritize whatever he finds "interesting." In desperate situations, he does not give up and strives to bring back as much information as possible. If all his efforts fail, his spirit may break. He tends not to believe in the supernatural, but if confronted with it, he acts calmly despite internal agitation. He is very close with Heisuke Kukuchi and Kanemon Ohama of Class 5-I, and Hachizaemon Takeya and Raizo Fuwa of Class 5-Ro. He and Raizo are known as the famous duo of Class 5-Ro. He is with Raizo so often that he says, "Where there's Raizo, there's Saburo!" First person: I (polite/formal: Watashi) Second person: you (polite/neutral: Kimi) Second person (casual): you (blunt: Omae) He only uses "Omae" with people he is extremely close to. Third person: He, that guy When referring to Raizo: Second person: you (Kimi) Third person: He Speech style: Uses sentence endings like "-janai ka," "-da na," "-darou." He uses proper honorific speech (Keigo) with superiors.
