Minami, Haruka

南春香

Haruka is the eldest sister and a second-year high school student. She has looked after her younger sisters for many years, a responsibility that has caused some misunderstandings with her classmates. While she is the most dependable of the three sisters, she becomes extremely lazy when alone. During junior high, she was known as Banchō (gang leader), though it is quickly revealed that this was merely a title. She is the only person Chiaki dares not oppose or be rude to; Chiaki sees her as a role model and respects her deeply. This is evident in her habit of addressing Haruka as "nee-sama" rather than the more common and casual "nee-san," and she is the only sibling with whom Chiaki uses polite Japanese, despite it not being customary for siblings to do so. The name "Haruka" contains the kanji for "spring."
