Hitohito Tadano is a high school student defined by cultivated anonymity. His appearance, academics, and athleticism reflect extreme statistical mediocrity: average height, weight, and clothing style, with black hair featuring a distinctive white flower-shaped cowlick. This deliberate ordinariness stems from a painful chuunibyou phase triggered by a rejection after a middle school confession. He possesses unexpected proficiency in ice skating and gift selection. His defining trait is an exceptional ability to "read the atmosphere," granting near-telepathic perception of social dynamics and unspoken emotions. This skill allows him to understand the nonverbal cues of Shouko Komi, who suffers from severe communication disorder. Despite this empathy, he often remains oblivious to romantic interest. His motto emphasizes blending in to avoid trouble, yet he discards it upon recognizing Komi's social anxiety. He becomes her inaugural friend, committing to help her achieve the goal of making 100 friends and serving as her primary support for social interactions and emotional reassurance. His family includes mother Tadano Jeanne (noted for her French name), father, and younger sister Hitomi Tadano. Hitomi starkly contrasts him with her energetic eccentricity and blunt demeanor; she practices ventriloquism, excels in judo, and frequently misreads his relationship with Komi, leading to comical intrusions. The siblings share a room, and Hitomi involves herself in his personal life, teasing him about Komi or assisting with gift purchases. Throughout high school, Tadano transforms from a timid, self-effacing individual into a more confident and resilient figure. He serves as class representative during his first and second years, often exploited due to his helpful nature. His relationship with Komi deepens through mutual dependence: he aids her social goals while drawing strength from her presence to confront his insecurities. Key milestones include traversing Valentine's Day exchanges, White Day gift anxiety, and eventual romantic reciprocation. His development includes overcoming jealousy, supporting Komi through competitions, and mediating friend group conflicts, notably reconciling with Rumiko Manbagi after a love triangle resolution. Trivia notes his handle name "†JIN-JIN†," a brief cross-dressing incident during a cultural festival where he was perceived as convincingly female, and interests in historical buildings. Quirks like masochistic tendencies (enjoying being whipped or stood on) are ambiguously attributed to the "Komi Effect." He ranked second in the series' first popularity poll.
