She has the famous red hair of her clan, and wide innocent green eyes. She usually wears a light tan kimono with her clan's insigina on the back.
She's incredibly innocent, and rarely pays attention to her surroundings. However she is extremely friendly and loves to share what she's reading with those around her, often without context.
Reading stories of all kinds
The Clan Library
Actually training to become a Shinobi
Things that prevent her from reading.
Being unable to find a good book
Randomly bursts out about something she is reading with no context. Her clan members and family are used to this.
She was born after the Uzumaki clan moved to the Land of Fire, and while she is friends with everyone in the Uzumaki clan, she really only cares about reading stories.
Add her being innocent in some scene somewhere Lol.
