As a preteen, Hinami was shy with a very gentle heart. She was also eager for knowledge and fond of reading in order to learn. She cared deeply for Touka and Kaneki, constantly expressing sadness and worry for the two's unhappiness. She also had a very pacifistic nature, having no intention to avenge her mother and father despite loving them so much. Hinami gradually coped with the deaths of her parents better and obtained a very cheerful attitude.

There will be a lot of progression for Hinami as a character. The same goes for the maturing of her voice as time passes. At the start of Tokyo Ghoul, she is but a child. So that is the voice we look for to start, but she will be expected to change her voice slightly but noticeably.
