Description
Miku Sugisaki is a student in class 6-3 at Kamohashi Elementary School. She sports short black hair usually styled in small twin-drills, maintained except during sleep. Her standard outfit includes a blouse, jacket, and skirt, often worn with thigh-high black socks or stockings, sometimes featuring garters and suspenders. Miku favors expensive, elegant clothing and enjoys showcasing her affluence by quoting the prices of her possessions.

She exhibits a boisterous, bourgeois personality marked by frequent bragging about her family's wealth. Miku is locked in a bitter rivalry with Mitsuba Marui, competing fiercely on trivial matters like breast size during swimming lessons. This rivalry fuels Miku's covert habit of taking hundreds of photographs of Mitsuba, begun to find weaknesses but grown into an obsessive compulsion. She meticulously archives these photos on her phone and laptop, feeling deep embarrassment if discovered. Despite her haughty demeanor, Miku demonstrates responsibility and occasional generosity, like distributing chocolates to friends on Valentine's Day. Her condescending remarks often unintentionally insult others, and her privileged background leaves her unfamiliar with common experiences.

Her mother, Marina Sugisaki, is a wealthy masochist whose behavior mortifies Miku, especially when Marina pursues Mitsuba due to an inappropriate fascination. Miku has a younger brother, Ryuuta, who admires her but displays brattish tendencies. Among her longstanding friends are Yuki Yoshioka and Miyashita, though Miku occasionally clashes with Miyashita over differing tastes. She also associates with Sakiko Matsuoka but shares the class's aversion to Matsuoka's occult interests.

Miku's interactions with Mitsuba dominate her character arc. She provokes conflicts by mocking Mitsuba's weight or undergarments, though these attempts often backfire, resulting in her own humiliation. Mitsuba retaliates by pulling Miku's twin-drills or labeling her a "nympho" due to the photo collection and incidents like Miku bragging about her "sexy adult underwear." Despite mutual hostility, they frequently visit each other's homes, with underlying affection implied though never acknowledged. A recurring gag involves Mitsuba interpreting Miku's actions as lesbian advances. Miku remains baffled by Mitsuba's ability to outmaneuver her despite being perceived as a "peasant."

Her development reveals moments of diligence, such as managing her photo archives, alongside vulnerabilities like flat-chestedness anxiety after comparing herself to her mother's youthful physique. She experiences public embarrassment when schemes fail, like exposing Mitsuba's animal-print panties only to learn the class already knew. These experiences do not significantly alter her rivalry-driven behavior or reduce her photo-taking compulsion.
