宮沢 有紀寧

Yukine is a second year student who hangs around in the library's reference room during lunchtime. Tomoya first met her in the library's reference room while trying to find a "how to" book about speeches. He is immediately greeted by her hospitality, and returns the next day with Youhei due to Youhei's insistence. Ever since, Tomoya, Nagisa, and Youhei start to enter the library reference room routinely.
