Omoharu Nakanaka, a student at Itan Private High School, embodies chuunibyou with her self-styled alter ego "Arsot Les Primavera" and theatrical flair. She dons an eyepatch over her left eye, bandages her left hand, and wears her black jacket rakishly draped like a cape, embracing a persona both mysterious and rock-inspired. Her dramatic naming conventions extend to others, dubbing Komi Shouko "Princess Komilia," though the origins of these titles remain shrouded in her own imaginative lore. Initially isolated by her eccentricity, Nakanaka tentatively seeks connection through grandiose gestures, proposing a "Blood Oath" to Komi and inventing shared mystical abilities like the "Dragon Force." Komi’s quiet empathy gradually bridges their communication gap, fostering mutual respect. Over time, Nakanaka navigates high school’s social labyrinth, transitioning from Class 1-1 to 3-4, shedding fragments of loneliness as she bonds with peers. A fervent gamer, she immerses herself in titles like *Swamp Bros* and *Battle Dome*, her room adorned with occult posters and manga shelves. Fictional power rankings in gaming scenarios fuel her competitive zeal. Her rivalry with Ren Yamai over Komi’s attention evolves into a prickly camaraderie, culminating in collaborative efforts like forming the band *Perorabio* for a cultural festival—a testament to her growing social confidence. Beneath her flamboyant theatrics lies vulnerability: challenges to her chuunibyou persona trigger embarrassment, revealing a shy, introspective core. Her birthday, February 29, and her name—a pun blending "middle" (Nakanaka) and "adolescence" (Omoharu’s kanji)—subtly mirror her archetype. Key moments, like acquiring the wooden sword "Darkness Kikuichimonji" on a school trip or organizing the band to hear Komi sing, illustrate her dual drive for imaginative expression and genuine connection.
