Loves his sister. Total siscon. However, his feelings toward Monjiro Shioe can be summed up as "strongest rivals who trust each other's abilities more than anyone else despite their constant clashing." Specifically, he holds these complex inner thoughts:

• "Just looking at his face pisses me off": Monjiro's "Gin-gin" intense attitude and inflexible, stubborn personality get under his skin, leading to immediate fights.
• "The budget-pinching nemesis": As Equipment Chairman needing repair funds, Monjiro (the stingy Accounting Chairman) is an opponent he refuses to lose to professionally.
• "Acknowledges his skill is the real deal": He has absolute trust in Monjiro's strength as a ninja, his passion for training, and their mutual capabilities.
• "He's the only one I'd trust at my back": In actual combat or crisis, he drops all personal grudges for perfect coordination. He believes "Monjiro will get it done" without needing words. Behind the mutual dislike lies deep respect as fellow 6th-years and hot-blooded men.

Tomezasaburo Kema (6th Year, Chairman): Belligerent, strong-willed, and hot-blooded, but has a refreshing personality and takes great care of his juniors. He is a hard worker who often gets caught up in the bad luck of his roommate, Health Chairman Isaku Zenpouji. Shuichiro Hama (4th Year): An extreme hot-head who is meticulous about polishing weapons and armor until they shine. He is so serious and motivated that juniors sometimes point out he's overdoing it. Sakube Tomimatsu (3rd Year): A reliable person of common sense who looks after his juniors well. He often acts as the committee's coordinator and has a kind side, helping timid lowerclassmen overcome their fears. Heita Shimosakabe: The most easily frightened and jumpy member of the committee. He sometimes panics over his own mistakes but is a hard worker growing with the support of his seniors. Kisanta Yamamura: Lives at his own pace and loves slugs, which are food for frogs. As his catchphrase "Hanya?" suggests, he has a laid-back and slightly mysterious aura. Shinbe Fukutomi: A glutton who moves at his own pace. He uses his plump physique to his advantage when filling in pitfalls dug by other committees or maintaining armor.

Monjiro Shioe (6th Year, Chairman): A very hot-blooded and powerful character whose catchphrase is "Gin-gin, gi~n!" Strict with himself and others, he is a combatant who prides himself on being the most "ninja-like" in the academy. Despite his rough appearance, he perfectly manages the academy's budget and bookkeeping. He stakes his life on protecting profits and cutting budgets, never allowing a single coin's loss. He devised unique training methods using a 10kg iron abacus and heavy coin bags. To Monjiro, Tomezasaburo Kema is his most frequent clash partner, officially described as "cats and dogs." However, they are bound by a complex and passionate bond of trust: ⚡️ The Ultimate Rival: They are two of a kind—hot-blooded, stubborn, and caring toward juniors. Their high pride leads to immediate physical brawls. 🤝 The One and Only Partner: Monjiro deeply respects Tomezasaburo's ninja skills and manhood. In missions or crises, they display perfect synchronization, trusting each other with their lives. He actually understands Tomezasaburo better than anyone else and unconsciously supports him when he's in trouble. Mikiyemon Tamura (4th Year): A self-proclaimed beautiful boy with a strong obsession with his weapons and beautiful things. While prideful, he has an endearing charm. Samon Kanzaki (3rd Year): Possesses the intense trait of being a "decisive person with no sense of direction." Always confident and quick to decide, but a troublemaker who heads in the completely wrong direction. Sakichi Ninokura (1st Year): Has high pride within his class but is a serious, reliable student suited for administrative work like calculations and bookkeeping. Danzou Kato (1st Year): Since his family runs a sign shop, he is a hard worker skilled at using an abacus and calculating. While very reliable, he has a cute side—he's not very good at writing characters.

The Accounting Committee handles all money and supplies for the academy. Their work includes: 📊 Budget Management: Hosting budget meetings, auditing proposals, and ruthlessly cutting wasteful spending. They accurately record daily income and expenditures. 📦 Supply Procurement: Tracking inventory of weapons, armor, stationery, and food. They authorize and pay for purchases by other committees. 🏋️ Unique Training: Per the Chairman's policy, they perform grueling physical training. The 10kg iron abacus is used for both calculation and as a weapon/weight. They carry heavy coin bags to strengthen their legs.

Reasons for All-Nighters:

• The night before the Budget Meeting: A total war zone as they must check and audit massive piles of applications.
• Closing the books: If the calculations are off by even one cent, Monjiro won't be satisfied, forcing everyone to recalculate all night until the numbers match perfectly.
• Features of their all-nighters: Juniors Sakichi and Danzou fight sleep alongside seniors. As everyone reaches their limit, Monjiro's "Gin-gin" intensity actually increases, terrifying his juniors.

Isaku Zenpouji (6th Year): Gentle and caring, a big brother figure to the Nintamas. He is so kind he cannot help but treat even an injured enemy.
