Description
Miharu Takeshita is a 16-year-old female student at Takizawa High School and Yamada's best friend. She acts as a grounding force against Yamada's highly sexualized behavior, frequently countering her friend's constant sex-related questions and schemes with dry sarcasm and visible exasperation. Despite this, she remains supportive, actively facilitating Yamada's relationship with Takashi Kosuda, such as by organizing a water park double date with her own college-student boyfriend, Daisuke Matsuo.

Physically, Miharu possesses pale skin, midnight blue eyes, and shoulder-length dark purple or black hair swept back to expose her forehead. Her most noted trait is her large bust size, specifically F-cup breasts, earning her the nickname "F-shita" from Yamada and frequently becoming a source of envy for her friend. She maintains a slender figure, evident during the water park outing. Her standard school attire includes a long-sleeved (occasionally short-sleeved) V-neck jumper over a plain white three-buttoned T-shirt (with only one button fastened), a dark blue navy skirt, and dark blue knee-high socks paired with penny loafers or plimsolls.

Miharu sustains a relatively stable romantic relationship with Daisuke Matsuo. She deliberately avoids discussing intimate details with Yamada to sidestep intrusive and lewd inquiries. It is implied she became sexually active after junior high school graduation and engages regularly, contrasting sharply with Yamada's inexperience. Miharu balances a strong will and academic diligence with frequent irritation at Yamada's antics, consistently offering pragmatic advice. She occasionally exhibits jealousy or competitiveness, particularly regarding male attention drawn by her bust size.

Throughout the series, Miharu's role shifts from supportive confidante to occasionally expressing frustration with Yamada's self-centeredness, yet their friendship endures. Her character serves primarily as a foil to highlight Yamada's extremes while offering moments of normalcy, without undergoing significant transformation herself.

Trivia notes: Her given name Miharu combines "beautiful" (美, mi) and "spring" (春, haru). Her surname Takeshita means "bamboo" (竹, take) and "under, below" (下, shita). Her birthday is February 18.
