Nenene Fujiwara 藤原寧々音

Toki's older sister (however she has no memory of him), in second grade and vice-president of the student council. Like her brother she has heterochromia but hides it by wearing glasses. She has a strange habit of grabbing Sakura's breasts out of nowhere (something her brother tries to do to Sakura as well), cuddling herself against them and falling asleep on them; going so far as to name them (Mii-tan for the right and Hii-tan for the left). Her behavior is childish most of the time.
