Description
Mei Yachiyo, codename Chiyome, is a 16-year-old student at Sorasaki High School, frequently seen in her second-year uniform. She has caramel-orange hair typically styled in a side ponytail and stands 160 cm tall. Her eyes are purplish-brown (mauve), shifting to magenta when she activates her enhanced abilities using the substance Spyce.
Her personality radiates enthusiasm, positivity, and cheerfulness, making her the most upbeat member of her spy organization, Tsukikage. She presents as self-assured, easygoing, and friendly, though prone to absent-mindedness and forgetfulness. This confidence allows her to face enemies with a smile during missions, maintaining strong faith in her teammates. Despite occasionally freeloading and being wasteful with money—often spending on snacks and unnecessary items, drawing scoldings—she demonstrates maturity in looking out for her teammates, especially her disciple, Fū Sagami. A significant shift occurs when she is revealed as a supposed traitor; her usually easygoing demeanor adopts psychopathic and sadistic undertones, later revealed as partly an act tied to her deep undercover role.
As a Tsukikage member, she mentors Fū and engages in street performances, playing guitar on corners to gather intelligence and earn money. Her story unfolds in the main series and the light novel gaiden *Golden Genesis*. Within Tsukikage, she is known for exceptional speed, utilized in recruitment tests, and wields kunai and shuriken as primary weapons.
Her key relationship is with Fū Sagami, her disciple whom she protects during missions, even shielding her from injury. They live together, often sharing a futon and sleeping while holding hands. Mei treasures a guitar pick gifted by Fū, and her singing voice reflects her emotional state, sounding sad after arguments until reconciliation. She planned a post-graduation trip to Ireland with Fū to see the aurora, describing it as romantic. She was apprenticed under Shin Kōsaka and interacts with teammates like Momo Minamoto and Goe Ishikawa. Her betrayal arc reveals prior affiliation with the antagonist group Mōryō; she leaked information as a deep cover triple agent aiming to destroy them from within. During this phase, she forcibly took Fū, stating her determination to hold onto her, and shared moments with Mōryō members like Kurara Tendō, including joining hands or clinging to her arm. Before a separation, she gave Fū a kiss on the head.
Her hobbies include singing and playing guitar. She feels at home in Fū's residence and enjoys eating her home-cooked meals. Daily, she balances school life with espionage duties, using musical performances for both income and intelligence gathering.
Her given name Mei means "life, command, fate," and her surname Yachiyo translates to "eight thousand generations." Her codename Chiyome incorporates the characters for "thousand," "generation," and "woman/daughter."
