Background / History

Student and Novelist

Utaha writes the light novel Love Metronome under the pen name Kasumi Utako. She has held two book signings at the bookstore where Luo Shu works and knows its manager. Despite presenting herself confidently as an author, she privately worries that her books sell fewer than twenty thousand copies per volume 3 5.

At school, she is the top student in her year, giving her considerable standing with teachers. She nevertheless says she has no real school friends and is ostracized by other girls. Students regard her and Eriri Sawamura as two of the academy’s prominent, unattainable beauties 6 15.

Giant Rat Encounter and Familia Contract

While escaping a giant rat barefoot, Utaha accepts a bicycle ride from Luo Shu. When they become trapped in a dead-end alley, she offers to boost him over the wall so that at least one of them can survive, asking him to notify her parents if she dies 1 2.

She instead agrees to his proposal to implant a mysterious device, activating the ritual that gives him the powers needed to kill the rat. Her recruitment supplies Luo Shu with 6,188 energy points and awakens her Mind Reading ability. She then directs their escape before the police can intervene 2.

At her apartment, Luo Shu treats her scraped feet. The system introduces him to her as an ancient deity rebuilding his lost pantheon, an explanation she accepts. She willingly embraces the lifelong Familia bond because it offers longevity, lasting youth, supernatural abilities, and the possibility of immortality if he ascends 3.

Founding the Astronomy Club

Utaha immediately participates in rebuilding the pantheon. She persuades the system to normalize surveillance footage of their escape and proposes recruiting influential public figures. After learning that recruits must possess the rare aptitude called “fate’s favor,” she helps develop a more discreet plan centered on a school club 4 5.

She brings Eriri to a rooftop meeting using a fake love letter, contacts a teacher, and secures the student council’s stamp before the faculty signature. Once the club is approved, she explains its supernatural purpose to Eriri inside the alternate-space headquarters and invites her to join 8 9 10 11 12.

Utaha also scrutinizes the fledgling organization’s finances, questioning whether Luo Shu can afford its monthly allowances and expensive membership bracelets. Her own influence generates an average of 100 points per month for him, less than Eriri’s contribution 13 14 15 16.

SDS Involvement and Occult Lessons

After Luo Shu joins SDS, Utaha offers Mind Reading for intelligence gathering and agrees to watch for personnel arriving at school. She recognizes both the opportunity to obtain official information and the danger of placing their Familia’s central figure inside another organization 41 42 43.

Luo Shu conceals her and Eriri’s powers from Natsuki Minamiya while arranging for them to attend her occult lessons. Utaha learns that the arrangement is intended to provide both education and a powerful ally, then joins instruction on Spirit Vision and supernatural threats 44 45 47.

Appearance

Utaha is described as an elegant, refined high school girl with long, straight black hair 2 3.

• White headband: Recognized by Luo Shu as her signature accessory 2.
• Wine-red eyes: Reflected in Eriri’s attempt to transform into her 14.
• First-seen clothing: A white women’s business jacket over a black satin dress 2.
• Black stockings: Worn during the rat encounter; removed while Luo Shu treats her injured feet 3.

Personality

Utaha is sharp-tongued and playful, frequently teasing Luo Shu about his divine status, seniority, and their apparent romantic relationship. Her practical jokes include using a love letter to summon Eriri and revealing Mind Reading while Eriri is transformed into her 3 8 9 14.

Her enthusiasm for the supernatural does not erase her conventional moral limits: she retreats when Luo Shu suggests an illegal or extreme approach. She is also financially cautious, challenging promised benefits and large expenditures rather than accepting them unquestioningly 5 13 15.

Despite trembling during the rat attack, she is prepared to sacrifice her chance of escape for Luo Shu. The experience leaves her anxious around alleys and eager for protection, prompting her to ask him to stay overnight and later consider requesting a Safe House entrance in her apartment 2 7 23.
