Movie
Description
Hansuke Doi serves as the theory teacher and homeroom advisor for the first-year Ha class at Ninjutsu Academy. Born 25 years ago in Fukuhara (present-day Kobe) to a noble family, he was orphaned during an attack that cost them everything. He later trained as a monk, mastering military strategy and ninjutsu, but a critical mission failure at age 19 left him injured. Rescued by Denzou Yamada and his family, this event redirected his path toward teaching. As a rogue ninja at the time, he couldn't use his real name; Denzou Yamada gave him the name "Hansuke" (meaning "half-done").
Standing 175 cm tall with an average build, Hansuke possesses a slightly youthful face, upturned eyes, and defined eyebrows. His long, messy brown hair is usually concealed under a ninja zukin or casual hat, revealing only his characteristic bangs; early depictions showed it in a messy ponytail. He typically wears a mulberry-colored hat, a white-and-blue kimono, and navy hakama, though his clothes often appear unkempt due to his demanding schedule. He also occasionally cross-dresses as "Hansuko" for specific missions or events.
A patient and dedicated educator, Hansuke frequently suffers stress-induced stomachaches from his students' academic struggles and forgetfulness. He deeply values his students, calling them "good kids" and defending their potential. He specializes in explosives and military strategy, though he sometimes errs in mixing gunpowder. He wields unconventional weapons like steel-reinforced attendance books, chalk, and blackboard erasers with exceptional precision, stating, "a ninja makes use of whatever he has." His daily challenges involve managing supplementary classes, administrative tasks, and household neglect, including forgotten rent payments or community chores.
His personal life reflects limited domestic skills, resulting in a messy home before student and fellow orphan Kirimaru Settsuno began living with him during school breaks. Their bond resembles a family, leading neighbors to speculate they are father and son or brothers. Hansuke assists Kirimaru with part-time jobs, becoming adept at babysitting and laundry. He maintains a mentor-like relationship with Denzou Yamada and a friendly rapport with colleague Kouji Makaino despite faction rivalries. His primary antagonist is rival ninja Moroizumi Sonnamon, who repeatedly challenges him after an initial defeat, though Doi typically repels him effortlessly. He harbors an extreme aversion to fish-paste products like chikuwa, citing shifting psychological reasons rooted in a story about choking.
In the film "Gekijо̄-ban Nintama Rantarо̄ Dokutake Ninja-tai Saikyо̄ no Gunshi," Hansuke faces a significant challenge, disappearing after losing a battle against Sonnamon and Zatto Konnamon. The narrative introduces a mysterious doppelganger named Tenki, who wears white clothing contrasting with Doi’s black attire. Adapting Kazuhisa Sakaguchi’s 2013 novel, the film centers on Doi’s struggle and his role being usurped at the academy.
Additional trivia notes his rise to the top position in a 2011 character popularity poll, his namesake origin from the author’s friend, and his iconic phrases like "I taught you this before!" borrowed from Denzou Yamada. His weaponized attendance book and concealed hair remain recurring elements across the series.
