Himiko Agari, a classmate of Komi Shoko at Itan Private High School, sports dark green hair tied in a high ponytail, green eyes behind glasses, and a curvier build, which fuels her self-consciousness about her physique, especially her bust. Crippling social anxiety triggers intense physical reactions—blushing, convulsions, hyperventilation, and stomach pains—often driving her to retreat into bathrooms or evade social contact. Though she bonds with Komi over shared shyness, her anxiety manifests more visibly through vocalized distress and trembling. Initially, her low self-esteem spirals into idolizing Komi, framing herself as unworthy of friendship and pleading to serve as Komi’s “dog.” This self-deprecating fixation softens through interactions with Komi and peers, though traces linger in her deferential mannerisms. Secretly, she adopts the pseudonym “Ramen is my staple food,” critiquing ramen with authoritative precision online. Her incognito reviews sway restaurant reputations, revealing a poised, articulate persona starkly opposed to her timid real-world self. Growth emerges as she invites friends to a ramen shop under her “Ramen Core” alias and tentatively sheds body insecurities during a public bath outing, contrasting Komi’s lingering reserve. Encouraged by Komi and Tadano Hitohito, she inches toward self-acceptance, cautiously embracing the label of “friend” over “servant.” Her involvement in the library committee and familial tie to Aunt Agari Matsuri surface alongside her cultural festival proposal: a Whack-A-Mole booth secretly designed to invite physical interaction with Komi. Her name puns on “stage fright” (*agari-shou*) and “cowardice” (*hikyou*), while her given name’s kanji hints at gluttony and self-loathing. Manga-anime discrepancies include height variations (5’6” vs. 5’1”) and nuanced dialogue shifts, like rephrasing her “dog” metaphor. The anime omits certain manga chapters but retains pivotal scenes—her library panic and tentative friendship gestures. Though no spin-offs center her, speculative concepts imagine her navigating college anxieties and forging new bonds. Portrayals in films, OVAs, or non-manga/anime media remain undocumented.
