OVA
Description
Seiya Sena, patriarch of the Sena family and founder of talent agency SenaPro, stands 183–185 cm tall with an AB blood type and a December 24 birthday reflecting his half-American, half-Japanese heritage. His sand-colored neck-length hair sweeps with one-sided bangs, while his heterochromatic eyes display yellow irises fading to blue at the top—a trait passed to his sons—accented by a distinctive mustache.
Scouted by his mother, Seiya debuted as an opera singer before rising to prominence in musical theatre, celebrated for his resonant voice and stage presence. A throat operation permanently altered his vocals, prompting his transition from performing to full-time production oversight and management of SenaPro, which he continues to lead.
He married model-turned-actress Nagisa Sena after she pursued him post-performance, their immediate mutual attraction defying her older age. Seiya prioritizes Nagisa’s happiness through devoted affection. Their two sons include eldest Shougo, vocalist for band Crusherz, and youngest Izumi, an aspiring manga artist.
Seiya discovered 18-year-old Rei Sagara destitute on the streets, offering shelter, education, and a role as his personal assistant. Rei evolved into SenaPro’s manager and a de facto family member, cementing fierce loyalty to the Senas. Though supportive of Izumi’s non-entertainment ambitions, Seiya gently nudges him toward show business, valuing industry unity for his family.
Occasionally forgetful and prone to overlooking details—requiring Rei’s damage control—Seiya balances optimism with absent-mindedness, underpinned by deep familial devotion. His parenting style merges encouragement with subtle pressure regarding Izumi’s career. He favors meat but despises umeboshi, and his name "holy night" uniquely diverges from the family’s water-themed naming tradition.
