Narumi Momose, later Narumi Nifuji after marriage, is a central character developed across official manga and anime adaptations. She has salmon-pink mid-back hair, frequently styled in braids, side ponytails, or fishtail braids casually, and light caramel-brown eyes. Standing 154 cm (5 feet), she contrasts with her partner’s 184 cm (6 feet) height. Professionally, she wears a pink blazer over a light pink blouse, brown stockings, a pencil skirt, and brown heels. Casually, she favors a marked white t-shirt with black shorts featuring white stripes, or a light blue shirt paired with a long peach/white skirt for dates. As a child, she sported neck-length hair and a yellow dress with pink flower patterns and white collars. Her personality revolves around intense image-consciousness, concealing otaku interests—Boys Love manga, otome games, idols, and doujinshi creation—from colleagues and family due to past relationship fallout upon discovery. She exhibits impulsiveness, impatience, and occasional thoughtlessness, balanced by observant and considerate traits. Insecurities about her chest size surface when comparing herself to Hirotaka’s busty anime figurine preferences. Despite this, she displays confidence in her hobbies and possesses high alcohol tolerance, often socializing at bars without intoxication. Gaming enthusiasm spans otome games, Mario Kart, and Monster Hunter, though she avoids excessive play. Born May 3rd, she shares Taurus traits with Hirotaka’s brother Naoya, fostering their similar personalities and close bond. Her background reveals she wasn’t always an otaku; childhood friend Hirotaka Nifuji introduced her via card trades, exchanging his cute-character cards for her powerful ones, igniting her enduring interests. She maintains a conflicted relationship with her otaku identity, blaming it for life struggles yet finding kinship among enthusiasts. Key relationships shape her arc. With Hirotaka, childhood friendship evolves into romance after he proposes dating, pledging support for her gaming and otaku pursuits. They marry in Volume 11, Chapter 86 of the manga, where she becomes Narumi Nifuji and later bears a son. Hirotaka’s unconditional acceptance—tabling at events for her and participating in cosplay—helps her embrace her passions. With senior colleague Hanako Koyanagi, a fellow fujoshi, she bonds after mutual recognition at a Sengoku Basara event, forming a deep friendship centered on BL recommendations and cosplay plans. This provides Narumi her first female friend sharing otaku hobbies, easing isolation. She also acts protectively toward Hirotaka’s brother Naoya, akin to a knight templar. Her development spans concealing her otaku identity at a new workplace to gradual openness after Hirotaka inadvertently reveals it, leading to friendships with Hanako and Kabakura. Initially viewing Hirotaka platonically, she impulsively agrees to date him following his promises of support, cultivating genuine romance. Marriage and motherhood mark milestones, showcasing her transition from self-conscious otaku to someone confidently balancing work, family, and fandom—creating doujinshi while caring for her child. This arc highlights her journey toward self-acceptance in both personal and otaku identities.
