Description
Futaba Isurugi, a second-year in Seisho Music Academy's Actor Training Department (99th Graduating Class), previously attended Keian Private Women's College Junior High Division. Her training spans traditional Japanese dance (Senka-ryu School) since 2005 and gymnastics at the S·A·C Shimogamo Action Club Gymnastics Workshop since 2010. She performed at the 2014 Traditional Dance Federation of Japan's "Cherry Blossom Viewing Festival" and secured third place in the National School Council's New Year Dance Performance for both 2015 and 2016.

Physically the shortest in her class, she sports amaranth hair in a forehead-exposing pixie cut and amethyst eyes. Her standard attire is Seisho's gray blazer uniform with a red ribbon tie; casually, she favors an oversized caramel hoodie or a green sweatshirt featuring a Daruma doll patch. For revues, she dons a gold-detailed purple jacket, pale purple pleated skirt, and red pelisse, wielding a halberd tipped with an amethyst gem.

Futaba balances a rough, sharp-tongued exterior with deep kindness and dedication. She harbors profound devotion to her childhood friend Kaoruko Hanayagi, supporting Kaoruko's success and happiness since childhood. Despite frequent complaints about Kaoruko's dependence, Futaba consistently handles tasks Kaoruko avoids, like manual labor or transporting her via motorcycle. This dynamic creates tension when Futaba challenges Kaoruko's stagnation, yet their bond remains foundational. Her determination extends beyond Kaoruko; she exhibits patience and reserve with others while actively pursuing self-improvement, such as refining her dance skills with Claudine Saijo after Claudine's revue defeat.

Her development involves asserting independence while upholding her commitment to Kaoruko. Initially defining her dream as "making Kaoruko happy," she later forges her own path by joining the New National First Theater Troupe. Entrusting her motorcycle to Kaoruko symbolizes this step. Their relationship sees further exploration through moments like Futaba giving Kaoruko massages and Kaoruko acknowledging gratitude, reinforcing their enduring connection despite Futaba's growing autonomy.

Additional trivia notes her name's meaning ("two leaves"), complementing Kaoruko's ("flower"), inspired by a sweets seller near Kyoto's Kamo River. She prefers kinako sticks, motorcycles, and precise work, disliking idleness and fish. The kanji in her surname relates to the perseverance proverb "Three years on a stone."
