Izumi Miyamura presents as a reserved, socially distant high school student, his long hair and glasses masking piercings and tattoos beneath a deliberately disheveled appearance. Beyond campus, he sheds this facade, revealing intricate body art and a relaxed, candid personality—a duality mirroring his struggle to balance self-expression with societal norms. Raised in a family bakery, he cultivates a pragmatic mindset, prioritizing future ownership of the business over academic pursuits unrelated to his goals, though he retains intellectual competence. Childhood ostracization and middle school loneliness eroded his self-worth, driving him to self-harm via piercings and suicidal ideation. These scars entrenched a conviction of being fundamentally unlovable, prompting further withdrawal. A brief bond with Kouichi Shindo alleviated his isolation temporarily, but high school revived his solitude until encountering Kyouko Hori. Their dynamic—rooted in reciprocal acceptance of concealed identities—sparks his emotional maturation. Hori’s disregard for his appearance empowers him to discard protective habits: trimming his hair, interacting more freely, and tentatively revealing his tattoos. Introspective and artistically inclined, Miyamura exhibits traits of an INFP and Enneagram 4w5, channeling acute empathy and aversion to conflict into creative outlets. His quiet compassion contrasts a dry, understated humor glimpsed among trusted friends like Shindo and Toru Ishikawa, who persistently question his negative self-view. Idiosyncrasies punctuate his demeanor: stumbling over certain Japanese phrases, avoiding horror films, and meticulously peeling tomatoes. Despite his unassuming exterior, he excels in Health studies and masters tongue twisters with practiced ease. Miyamura’s arc traces a shift from defensive seclusion to deliberate openness, epitomized by shorter hair and unconcealed tattoos. This transformation parallels his reconciliation with past pain and deliberate choice to nurture authentic relationships, framing his journey as a testament to embracing vulnerability as strength.
