Subaru Akehoshi is an idol under STARMAKER PRODUCTION and a core member of Trickstar. His late father, an idol whose career ended in scandal and arrest, left Subaru with complex childhood emotions. This drives Subaru to become an idol spreading genuine happiness, aiming to redeem his father's legacy while forging his own identity. He lives with his mother as an only child and owns a Shiba Inu named Daikichi. Subaru has bright blue eyes and vibrant orange hair styled short and tousled, standing 170–171 cm tall. His stage outfit includes Trickstar’s red plaid jacket with black and gold accents, black pants with red stripes, orange sneakers, and accessories: a fingerless glove, star-patterned wristbands, and a four-pointed star necklace symbolizing Trickstar. Casually, he wears layered T-shirts with color blocking in warm weather and puffy jackets over sweatshirts in cold seasons, often with untucked belts and rolled cuffs. Energetic and optimistic, Subaru acts as a mood-maker who values positivity and openly expresses affection. He adores anything sparkly—coins or jewels—for aesthetic rather than material reasons. Despite his playful demeanor, he ranks near the top of his class academically and is highly observant. He dislikes nicknames for himself but assigns them to others, like "Hokke" for Hokuto Hidaka or "Ukki" for Makoto Yuuki. While physically affectionate with close friends, he avoids those disregarding his boundaries, causing initial friction with individuals like Chiaki Morisawa. During his first year at Yumenosaki Academy, peers shunned him for his enthusiasm and work ethic. This isolation ended when Trickstar befriended him, helping him overcome that "dark time." Subaru credits the unit for his emotional recovery, stating he can "smile through thick and thin" with their support. His fear of darkness and isolation reflects his need for companionship. Professionally, Subaru performs with a "radiating voice" and vibrant energy, aspiring to make audiences smile like his father once did. His activities span music, variety shows, and acting—he dreams of starring in a school-themed TV series as a teacher. He shares a comedy partnership with Makoto Yuuki called the "Idiot Combo," though peers like Hokuto acknowledge his instinctive performance skills and reliability. Post-graduation, he evolves as an idol under STARMAKER PRODUCTION, balancing lighthearted entertainment with serious artistry. Key trivia: His birthday is June 22, blood type O, and he was in the basketball club. He dislikes cooking but loves his mother’s home cooking. His autograph features a star symbol, and he impersonated the tokusatsu hero Go-On Silver during live events. His name meanings—"Pleiades" (Subaru) and "morning star" (Akehoshi)—tie to his love for celestial sparkle and Trickstar’s theme.
