Ueno Naoka (植野 直花, Ueno Naoka) is a character in the Koe no Katachi series.
Ueno has long, straight, dark hair that reaches to her middle back, long fringes that reach to her nose, black-purple eyes, and a pale complexion. She is normally seen in her school uniform: a traditional white and red sailor fuku uniform, along with a dark skirt and a tan school sweater. Ueno is also shown in her part time job uniform, in which she wears glasses and ties up her hair as well as her bangs, making her unrecognizable to those who search for her in her workplace.
Ueno is a rather blunt and straightfoward person, being rude and frank to people she dislikes, especially to Nishimiya. Ueno, being the "traditional tsundere", has been shown to be somewhat dull and insensitive to many of the characters, although she admits to this and is hesitant to change. Despite this, Ueno has shown a soft and sweet side towards the end of the manga, and can also become flustered relatively easily. It is also hinted more than once that she has a crush on Ishida, a childhood friend who assisted in the bullying of Nishimiya .
Towards the end of the manga, Ueno displays progress of changing her ways, attitude, and mindset towards others, and releases most of her tunnel vision views towards her friends and others around her. She later shows remorse for her earlier actions and apologizes to those such as Ishida, and attempts to with Shouko.
