Background / History

Family and Secret Career

Eriri comes from two prominent families. Her father works for England’s diplomatic service in Japan and belongs to the noble Spencer family, while her mother, Sayuri Sawamura, comes from the locally prominent Sawamura family. Her parents are wealthy, protective, and personally manage her doujinshi business 9 10.

She has drawn late into the night since elementary school. Under the pen name Kashiwagi Eiri, she publishes adult NTR doujinshi online while maintaining the public image of an exemplary wealthy young lady. She avoids discussing anime or manga at school, and even her fans do not know her real identity 9 10 23.

Recruitment into the Astronomy Club

Luo Shu selects Eriri as the prospective third member needed to establish the Astronomy Club, believing she has the aptitude for supernatural awakening. Utaha brings her to the rooftop with a fake love letter. Eriri intends to refuse the club invitation until Luo Shu addresses her by her secret pen name 6 9.

Although Luo Shu says he will not expose her, Eriri interprets his approach through rumors that he has yakuza connections. She agrees to join but warns that her parents will retaliate if he blackmails her. She then helps secure the club’s approval and offers to fund its supplies in exchange for keeping her identity secret 10 11 12.

Her understanding of the club changes when Luo Shu transforms its empty classroom into an alternate-space headquarters. Initially frightened, she asks whether she can quit. The promised ability awakening, monthly allowance of fifty points, medical care, and mission support persuade her to accept formal membership 12 13 14.

Awakening and Early Practice

Eriri signs the membership contract and awakens Transformation. Her first experiment imitates Utaha, but the revelation that Utaha can read minds shocks her into reverting and fainting. After recovering, she incorrectly concludes that Utaha’s Mind Reading must have been how Luo Shu discovered her pen name 14 15.

At home, Eriri discovers that her nearsightedness has disappeared and that fast cycling barely tires her. She practices by transforming into Sayuri, only for her mother to enter and mistake the transformation for makeup or a costume. The encounter convinces Eriri to restrict future practice to the Astronomy Club’s secure headquarters 23.

Occult Education

Eriri uses her school contacts to check rumors about an incoming transfer student and voices concern that an official ability instructor might uncover the group’s secrets. Luo Shu subsequently arranges for Natsuki Minamiya to teach the club occult studies while upgraded bracelets conceal the girls’ powers 43 45.

Under Natsuki, Eriri successfully activates Spirit Vision with essential oil and learns to interpret the three flames of essence, vital energy, and spirit. After laughing at Natsuki’s difficulty being recognized as an adult teacher, she and the other students receive homework to practice Spirit Vision without the oil 46 47.

Appearance

• Hair: Naturally blond, usually worn in twin tails 9 10 23.
• Eyes: Azure 14.
• Features: Delicate and attractive; regarded at school as an unattainable beauty comparable to Utaha 6 9.
• Clothing: Shown wearing Toyogasaki Academy’s uniform during her first evening of ability practice 23.
• Former vision aids: Wore glasses from childhood and later contact lenses; her prescription had exceeded minus four diopters before her eyesight recovered 23.

Personality

Eriri carefully separates her polished school persona from her private interests. Popular since childhood, she is accustomed to receiving confessions and has prepared polite rejection lines. Her refusal to acknowledge Tomoya Aki at school reflects her concern about being associated publicly with anime fandom 9 10 11.

Her composure breaks quickly when her secrets are threatened. During recruitment, she imagines increasingly alarming blackmail scenarios, yet still negotiates, invokes her family’s protection, and demands that Luo Shu fulfill his promises. Her enthusiasm for supernatural powers becomes much clearer once she sees the contract and its stated benefits 10 12 14.

Eriri is easily flustered and openly argumentative with people close to her. She holds a grudge against Utaha for frightening her, protests Sayuri’s teasing, and becomes embarrassed when Natsuki discusses sexual physiology—even though she privately creates adult comics. She nevertheless recognizes Luo Shu’s organizational skill and comes to appreciate the need for a secure base 15 23 47.

• Bicycle — Used for her school commute and her first informal test of improved stamina 8 23.

Relationships

• Sayuri Sawamura — Mother and one of Eriri’s demonstrated transformation subjects. Shares anime interests with her daughter and mistakes the supernatural imitation for skillful dressing up 23.
• Father — An English diplomat and aristocrat. Helps manage Eriri’s doujinshi business; Eriri cites his wealth and protectiveness when warning Luo Shu against blackmail 9 10.
• Tomoya Aki — Childhood friend whom Eriri ignores at school. She is embarrassed by his public insistence on using a school room to watch anime 10 11.
• Natsuki Minamiya — Occult teacher and Astronomy Club advisor. Teaches Eriri Spirit Vision and assigns unaided practice after Eriri laughs at her predicament 44 46 47.

Trivia

• Recruiting Eriri awards Luo Shu 9,000 points and adds 300 points to his monthly income—three times Utaha’s contribution. The system attributes the difference to Eriri’s greater social influence 14 16.
• Eriri asks whether she can buy internal points with cash and privately considers paying ten thousand yen per point, but Luo Shu refuses to offer that exchange 13.
