Omoharu Nakanaka, a student at Itan Private High School, embodies chuunibyou tendencies—a phase defined by theatrical delusions and a hunger for recognition. Adopting the alias Arsot Les Primavera, she casts herself as a warrior from a concealed fantasy realm, dubbing Shouko Komi "Princess Komilia" without elaborating on the mythos. Her aesthetic mirrors this alter ego: a black eyepatch obscuring her left eye, bandages winding around her left hand, and edgy, rock-infused attire amplifying her theatrical presence. Initially grappling with isolation due to her eccentricity, she wields her chuunibyou persona as a shield against loneliness. Early overtures to befriend Komi involve dramatic gestures like summoning a "Dragon Force" and pledging blood oaths, though these theatrics initially confuse others. Despite clashes with rival Ren Yamai over their shared fondness for Komi, their dynamic matures into a prickly camaraderie rooted in grudging respect. Her arc transitions from social solitude to active engagement, joining Najimi Osana’s circle in her second year. She partakes in group outings like summer festivals and co-founds the band Perorabio for the cultural festival—a creative outlet and covert scheme to hear Komi sing. These endeavors showcase her knack for merging imaginative flair with authentic connection. A fervent enthusiast of gaming, manga, and anime, her bedroom doubles as an occult-themed den adorned with posters and collectibles from series like *Swamp Bros* and *Battle Dome*. The wooden sword "Darkness Kikuichimonji," acquired during a Kyoto school trip, underscores her devotion to fantasy. Despite her bold facade, she flusters easily when others critique her chuunibyou antics, betraying a shy, vulnerable core. Her name carries coded symbolism: "Nakanaka" phonetically nods to "chuunibyou," while "Omoharu" merges kanji for "belief" and "adolescence," echoing her self-styled mythos. Gradually, she shifts from relying on fantasy roles to cultivating real bonds, even seeking Tadano’s aid in interpreting Komi’s silence—a step signaling newfound empathy. Frequent class transfers mirror her unstable social standing, yet covert admiration from male peers and a fifth-place school poll ranking hint at latent popularity. By her third year, she stabilizes within her peer group, balancing her vibrant individuality with the pull of acceptance—a journey tracing her maturation in embracing both imagination and tangible relationships.
