Matsudaira Chiyo

Biodata

Background / History

Chiyo comes from a wealthy Matsudaira family. Tanaka Hikaru describes her as an heiress of noble blood, linking her ancestry to the kinship daimyo related to the Tokugawa family. Her mother chairs Jinguji High School’s board of directors, giving Chiyo considerable influence within the school 28 37.

According to Hikaru, Chiyo was already known for helping others at Jinguji Junior High School. He also reports that many grants and scholarships at Jinguji’s junior and senior high schools were established at her suggestion. She later founded the Support Club out of personal interest to assist students in need 29 37.

Appearance

Chiyo has fair skin, long, silky black hair, and a pretty face. At school, she generally wears her hair loose 28 37 42.

• School uniform: Black uniform with a red chest ribbon, black pleated skirt, and black over-the-knee socks 28.
• Reading glasses: Wears rimless glasses with black arms while working at her desk 37.
• Outside-school disguise: Two braids, thick round-lensed glasses, and makeup that gives her skin a yellowish tint and adds freckles. Ah Xiu applies the disguise, making her look like a different person 28 42.
• Casual clothing: Wears black casual clothes during her visit to the Takasaki Izakaya 42.

Personality

Chiyo combines a refined manner with confidence in her wealth and connections. She remains composed when Naruto mocks her status and teases him in return, once suggesting that his eagerness to visit her might make him a “tsundere.” Naruto nevertheless remembers her earlier izakaya behavior as aggressive and narcissistic 28 37.

She treats repayment of kindness as a family obligation. Rather than simply granting Naruto exemptions from school rules, she finds a loophole that lets him earn wages while fulfilling his club requirement. Her concern for the Takasaki Izakaya also extends beyond supplying temporary help: she researches competitors and considers changes intended to make the business sustainable 28 29 38 42.

Her protective behavior can be markedly cruel. She affectionately wipes dust from Takasaki Tsuki’s face after an assault, but deliberately scalds the attacker’s arm to expose his fake tattoo. She also watches a living, filleted fish perform “skeleton swimming” with relish, prompting Naruto to privately call her cruel 42 43.
