Background / History

Rikki was initially introduced as a reserved Hanasakigawa student who disliked becoming the subject of other students’ attention. Her early encounters with Ogura Asahi began poorly: she regarded Asahi’s confidence and promise to solve any problem as arrogant and condescending. 114 122

During her class self-introduction, Rikki identified herself as a drummer whose hobby was listening to music and whose preferred genre was rock. She had already played in a band before, but that group later disbanded. 117 196

After the dissolution of Crychic, Rikki reunited with Takamatsu Akari and Nagasaki Sōse in a new, incomplete band. Although she wanted to move forward, she remained conflicted about the former group and whether its past members could ever perform together naturally again. 360

Rikki took charge of finding the band’s final member. Despite concerns over Asahi’s health and unreliable attendance, she personally invited Asahi to join as a flexible guitarist, keyboardist, or utility player. Asahi accepted immediately, completing the lineup. 406 446 447

Appearance

Rikki is 156 cm tall, with long, straight dark hair, sharp eyes, and a distinctive beauty mark. Her intense gaze and composed bearing can make others feel intimidated. 193 196 408

• Wore a black café uniform top with blue trim while working at RiNG. 359
• Uses drumsticks during performances and gives the band’s opening cue from the drum kit. 548
• Received a personalized stage outfit designed to remain comfortable and unrestricted while drumming. 625

Personality

Rikki is blunt, disciplined, and easily irritated by carelessness, deception, or people who fail to take band activities seriously. She is particularly skeptical of Asahi’s constant excuses, school-hopping, and tendency to avoid scheduled practices. 407 459 510

Her severity is directed at herself as much as at others. She insists that underprepared members should improve through practice, takes responsibility for arranging rehearsals, and worries about the band embarrassing itself before more experienced musicians. 510 575 632

Beneath her abrasive manner, Rikki is protective of Akari and emotionally invested in the band’s stability. Asahi’s reminder that she had not remained beside Akari after Crychic disbanded forces her to confront her guilt rather than blame others for the past. 447 513

Rikki is also prone to embarrassment when praised, teased, or confronted with her admiration for Afterglow. Though she compares herself unfavorably to Asahi’s overwhelming talent, she accepts guidance and continues working to improve as a musician. 488 578 682

Abilities & Skills

Drumming

Rikki is an experienced drummer who had performed with a previous band before working at RiNG. 196

• Provides controlled rhythm during the band’s rehearsals and performances. 578
• Signaled the start of the group’s debut performance of “God Knows” with her drumsticks. 548
• Can become tense around musicians she admires, particularly Afterglow, but regains her rhythm after settling herself. 630

Composition

Rikki began studying composition after Takamatsu Akari wrote lyrics for the band.

• Volunteered to compose music for Akari’s lyrics rather than leave the work entirely to Asahi. 578
• Studies music theory, arranging, and DTM through resources recommended by Asahi. 623
• Completed “Azure Sky Companionship,” which the band performed successfully in a single take. 682
• Later agreed to divide songwriting duties with Asahi while Akari handled lyrics. 707

Band Organization

Rikki frequently acts as the group’s practical organizer and disciplinarian.

• Secured MyGO!!!!! a joint Live opportunity with Poppin’Party and Afterglow despite the group’s lack of rehearsal time. 487
• Schedules recording-studio practices and directly confronts members who skip them. 510
• Pushed for the group to prepare a second song for a ten-minute Live set. 578
• Immediately began assessing songs, venues, promotions, and scheduling when an emergency series of Lives was proposed. 733

Relationships

• Ogura Asahi — Classmate and bandmate whom Rikki personally recruited as the band’s final member. Their relationship is defined by constant bickering, mutual reliance, and Rikki’s frustration with Asahi’s absences and teasing. 406 446 510
• Takamatsu Akari — Former Crychic bandmate and current vocalist. Rikki is highly protective of Akari, but must confront the fact that she failed to stay beside her after Crychic disbanded. 447 513
• Chihaya Aine — Guitarist and frequent verbal sparring partner. Aine’s optimism and casual attitude often clash with Rikki’s strictness, though the two become increasingly familiar through their arguments. 578 579
• Nagasaki Sōse — Bassist and former Crychic bandmate. Rikki openly challenged Sōse’s delayed recruitment efforts by bringing Asahi into the band herself. 409 448
• Hachiman Kairin — Classmate and friend. Rikki trusts Kairin’s opinions, shares food and drinks with her, and has considered that they might work well in a band together. 360 510
• Afterglow — A band Rikki admires intensely. Her nervousness around its members and eagerness for signed photographs repeatedly expose her fandom. 488 630 632

Story Role / Major Arcs

Completing the Band

With the group still missing a guitarist or keyboardist, Rikki approaches Asahi and asks her to join. Her decision frustrates Sōse, who had intended to recruit someone herself, but Rikki refuses to let the band remain incomplete indefinitely. 360 406 409

Debut Live

Rikki reluctantly wears the group’s maid-style debut outfit after Akari persuades her. Facing a huge Hanasakigawa crowd, she is nervous but performs her role, starts “God Knows,” and is moved to tears by the performance’s success. 548 549

Becoming a Composer

When Akari brings lyrics to rehearsal, Rikki takes responsibility for composing them. Though Aine initially suggests letting the more skilled Asahi handle the work, Asahi refuses in order to support Rikki’s development. 578

Rikki studies consistently and eventually completes “Azure Sky Companionship.” The song’s successful one-take rehearsal proves her growth, even as Asahi’s effortless mastery of it leaves her frustrated. 623 682

Building a Band Identity

Rikki helps lead the transition from an informal group into a functioning band through regular practice, original songs, and coordinated stage outfits. While she initially questions whether the temporary group even needs an official name, she continues to shoulder practical responsibilities for its performances. 625 626
