Nozomi is a very kind, positive and caring girl, but she has been clumsy, awkward and a crybaby since she was young, in which she is prone to crying and blushing. She is also quite naive, very pure-hearted and sweet, but at the same time has always been an understanding, supportive and strong-headed girl that tries her best in everything since she hates losing. She is very honest and straightforward regarding her feelings towards Keiichi and is very determined and also a bit pushy to make him fall in love with her. According to Keiichi, her intuition is always spot which is why she tends to do something out of absolutely nowhere. She is sometimes seen as meek and shy, but is friendly with everyone, disciplined and polite. Nozomi had also been very innocent and dependable on other people, which is why she couldn't really make decisions herself, but after falling in love with Keiichi, Nozomi becomes a more confident person and leaves her self-resentment behind. She finally felt a sense of fulfillment after feeling so anxious after seeing friends finding their passions when Nozomi herself really didn't have anything she wanted to do. And even though she has been said to look quite fragile, Nozomi absolutely hates being called this because of her past.

She is now able to set her goals and choices in life and realized the things she was yearning for. This is why she has decided to live for love as she was deeply changed by meeting and falling in love with Keiichi.

However, it has been slightly hinted that she is a masochist due to her responses when Keiichi shows her his sadistic side, and this side of her was also most likely brought out by him.
