Nadeshiko is the president of the track and field team. Due to observations of her past classmates she reached the conclusion that relationships are a weakness. She then became strived to forget about love and focus on her running.
She was a member of the comitee trying to disband the Eiken club, She challenged Yuriko Shinonome and Densuke Mifune to a race to decide the clubs fate and prove to Yuriko who is also a star runner that love weakens you. She won the race but Eiken won the challange when Yuriko was able to knock 5 minutes off her best time, proving to Nadeshiko that love can make you stronger.
It was also hinted that she likes Densuke too. Not surprising really.
