Pripara Wiki)
Unlike her older sister, Non is very mature, intelligent and knows a lot about idols. She also tends to act as the older sibling in the family, taking care of Laala when she's sick and scolding her when she does something silly.
Even though she often says that she wants to surpass her sister, and even mocks and scolds her sometimes, she respects Laala greatly and is ready to defend her when someone says anything bad about her.
Season 3 Spoilers
~!In season 3 Non received her PriTicket and became a proper idol. Initially she settled on hiding her identity and creating 3 different versions of herself (Kanon, Pinon and Junon) to form the ultimate unit, but after losing to SoLaMi♡SMILE she abandons this idea and later forms an idol unit with Tsukikawa Chili and Taiyou Pepper called NonSugar !~
