Description
Haruka Isumi is the 17-year-old vocalist and double center of the idol group ZOOL. Standing 170 cm tall with a December 6 birthday and blood type B, he attends classes with Iori Izumi and Tamaki Yotsuba. He maintains a self-centered demeanor, mirroring indifference to those who ignore him first. His preferences include sweet foods and video games, and he holds a strong dislike for powdered medicine.
Orphaned young, he was raised by his paternal grandmother. During overseas training under Kujo Takamasa, his grandmother concealed her hospitalization to protect his idol ambitions. Kujo taught him to devalue audiences as "poison," fostering his initial cynicism. After Tenn Kujo's rise led to Haruka's abrupt abandonment, he harbored deep resentment toward both Kujo and Tenn. This bitterness made him susceptible to recruitment by Ryo Tsukumo into Tsukumo Productions and ZOOL.
His childhood motivation for becoming an idol was to provide his grandmother with a new husband and ease burdens like roof repairs, contrasting his abrasive exterior with familial devotion. Trauma from abandonment fuels distrust and hostility, especially toward figures tied to his past failures.
Within ZOOL, relationships evolved from superficiality to gradual camaraderie. He initially dismissed friendship among members. However, when his grandmother faced a roof leak crisis, Minami Natsume, Toma Inumaru, and Torao Mido demanded to help with repairs. Haruka protested but relented, revealing vulnerability. Concurrent discussions about solo songs saw Minami agree to compose after Toma's encouragement. Haruka explicitly stated he would only sing if Minami wrote the songs, signaling growing respect. The group's collective decision to support his grandmother marked a turning point, subtly softening his resistance to reliance.
His interactions show lingering defensiveness, like demanding members avoid sharing embarrassing stories such as his struggle with RabbitChat. Yet, moments of accepting help or participating in group endeavors illustrate incremental growth toward interdependence, though his core resolve and sharp demeanor persist.
