宮内 沙紀

Subaru's childhood friend, and neighbour. Saki gets on well with Subaru's parents, and is treated as family. Because of her childish nature, even though she is the same age as Subaru, she is seen more like a little sister. Serious and diligent, Saki's school grades are fairly good. Subaru often gets Saki to do his homework for him. Blindly in love with Subaru, she chases after him like a puppy everyday.
