Inaho Yamato, a student at Hyakkaou Private Academy, serves on the Election Committee. Her primary duty is overseeing gambling matches during the student council presidential election to ensure fairness and prevent cheating. She wears an orange dog-themed hoodie over the standard female uniform, signifying her committee role. Her appearance features short dark brown hair styled in a hime-cut, brown eyes, and short, pointy eyebrows. Her personality is cheerful, polite, and diligent. While typically friendly, she adopts a serious and intimidating demeanor when enforcing rules, emphasizing the importance of the observers' work. She demonstrates significant enthusiasm and motivation in her position. Her responsibilities include inspecting gambling equipment, declaring match rules, and intervening when necessary. For instance, during the Finger Guillotine game involving Yumeko Jabami, Midari Ikishima, and Erimi Mushibami, she inspected the machine, removed table stoppers at Yumeko's request, and disqualified Midari for cutting two strings simultaneously, violating the rules. She later presided over Mary Saotome's gamble against Ririka Momobami, confirming that escalating stakes were permissible with mutual agreement. She actively participates in election logistics, such as preparing for the auction and reporting vote distributions to Runa Yomozuki. When Yumeko requested 3 billion yen during a gamble, Inaho coordinated with other observers to deliver the funds. She expressed astonishment at unconventional voting methods like "Scumcoins." In the spin-off *Kakegurui Twin*, she appears during the school festival, explaining rules and overseeing a gamble involving Eneru Rokujou, Tsuzura Hanatemari, and Yukimi Togakushi. While performing her duties as an impartial referee, she casually complimented the participants' physical appearance.
