koshigaya natsumi
A Main character from Non Non Biyori, Younger sister of Koshigaya Komari and Koshigaya Suguru
A bad student and a trouble maker compared to her more straight laced sister.
She's taller than her very short older sister but shorter than the younger very overdeveloped Ichijou Hotaru.
Emotionally she's more mature than her easily upset older sister however she is childishly irresponsible and often acts lazy.
She often pesters her older sister and sometimes treats her like a child however deep down she still respects her older sister.
Like Miyauchi Renge she sometimes calls Komari "Koma-chan", however this is generally intended as pestering. Normally she simply calls Komari onee-chan.
In season one it's revealed that she used to have a childhood crush on her older brother Koshigaya Suguru.
