Description
Haruka Isumi is a 17-year-old male student who attends the same school as Iori Izumi and Tamaki Yotsuba. Standing 170 cm tall with green hair and yellow eyes, his blood type is B, and his birthday falls on December 6. He serves as the vocalist and double center for the idol group ZOOL, represented by the fermata music symbol. Haruka enjoys sweet foods and games but has a distinct dislike for powdered medicine.
Orphaned at a young age, Haruka was raised by his paternal grandmother. His path took a difficult turn during idol training overseas under Kujo Takamasa. His grandmother was hospitalized during this period but concealed her illness to avoid disrupting his dreams. This marked the start of Haruka's distorted development, as Takamasa taught him to devalue audiences, viewing them as "poison." Ultimately branded a "failed experiment," Haruka was abandoned when Takamasa shifted focus to Tenn Kujo's rise. This fueled a deep hatred towards both Kujo and Tenn. Ryo Tsukumo subsequently recruited Haruka into Tsukumo Productions and later into ZOOL.
Haruka projects a self-centered and defiant personality, encapsulated in his declaration: "I’ll turn what they think are angels into devils." He refuses to acknowledge those who do not acknowledge him, masking underlying vulnerability rooted in his trauma. His relationships reflect complexity: he uses formal last names for peers like Iori Izumi ("Izumi") and Minami Natsume ("Minami"), yet accepts the nickname "Isumin" from Tamaki Yotsuba. Within ZOOL, Toma Inumaru calls him "Haru," and Torao Mido uses "Haruka," indicating closer bonds.
Notable traits include competitiveness and occasional immaturity, exemplified by arguments with Tamaki during physical education classes over flexibility, which resulted in collective punishment. Haruka approaches responsibilities seriously, conducting meticulous research for projects like a Valentine's "perfect date" simulation. However, he dismisses peers' suggestions as unreliable and rejects Torao Mido's adult-oriented date ideas as incompatible with his teenage identity, seeking authentic alternatives.
A poignant childhood memory involves crafting origami flowers and attempting to cook onigiri for his grandmother's birthday, showcasing early devotion and innocence that contrasts with his later cynicism. This memory resurfaces when he learns his grandmother avoided burdening him during her hospitalization, exacerbating his isolation.
His character arc suggests potential growth, as his voice actor expressed hope for him to "meet kind people and live honestly," indicating a trajectory beyond his current resentment. While his backstory and interactions reveal lingering bitterness, his involvement in ZOOL and gradual openness to collaboration hint at ongoing development.
