Description
Tsumugi Takanashi is the primary manager for idol group IDOLiSH7 at her father's agency, Takanashi Productions. Her surname, meaning "absence of hawks," metaphorically signifies a safe space for small birds, reflecting her supportive role. She joined the agency straight from high school with no prior management experience. Her mother passed away during her childhood, and she shares a long-standing bond with Banri Ogami, whom she views as an older brother figure, having given him Valentine's chocolates in her youth. She also has a childhood connection with idol cadet Makoto Kurosaki.

Tsumugi's personality combines politeness, kindness, optimism, and energetic dedication to IDOLiSH7. She exhibits occasional clumsiness and struggles to keep secrets, similar to Riku Nanase's transparency. Despite her generally gentle nature, she demonstrates sarcasm and a stern demeanor when reprimanding the group. A natural workaholic, she often works late into the night sustained by energy drinks and instinctively prioritizes work-related locations when considering travel destinations.

Professionally, Tsumugi proactively develops skills to support the group. She learned stage design specifically to secure IDOLiSH7's inclusion in Zero Arena's inaugural concert and acquired driving proficiency to enhance logistical management. Her responsibilities extend beyond scheduling and training; she provides emotional support during conflicts, such as mediating between Mitsuki Izumi and Yamato Nikaido. She collaborates closely with Iori Izumi, who unofficially assists with managerial strategies. Her stage production studies led her to discreetly observe TRIGGER rehearsals, facilitated by Gaku Yaotome's suggestion of a disguise.

Her relationships with the idols blend professionalism and personal care. IDOLiSH7 members typically address her as "Manager," though Nagi Rokuya uses "Tsumugi" and engages in playful flirtation without romantic intent. Gaku Yaotome of rival group TRIGGER harbors romantic feelings, inviting her to meals and offering concert tickets (which she insisted on purchasing as a fan) and transportation (intervened by her father). Tsumugi consistently declines his advances, citing the manager-talent boundary and their families' longstanding feud. Tenn Kujo occasionally uses "Tsumugi-chan" to irritate Gaku. With Re:vale members, she shares informal interactions in "Rabbit Chats," indicating friendship. Her familial loyalty surfaces during agency events, such as participating in an IDOLiSH7 impersonation skit with her father and Banri during New Year celebrations.

Across the series, Tsumugi evolves from an inexperienced newcomer into a resilient manager. Her dedication is tested through industry challenges and complex interpersonal dynamics, yet her core motivation remains unwavering: to witness IDOLiSH7's continuous growth in singing and dancing. This commitment defines her managerial philosophy and personal fulfillment.
