Nanako Hazuki

Nanako Hazuki is the sister of Nagisa Hazuki.

Appearance
Though Nanako is not seen in the anime, Director Hiroko Utsumi has stated that she likely has blonde, shoulder-length hair. She would be most often seen wearing a mint green headband and bracelet. Her eyes are light blue, unlike Nagisa's. Utsumi has also made it clear that this was just a quick thought of what she might look like.

Personality
Nanako has a calm demeanor. She is often annoyed with Nagisa when he begins to become loud or rambunctious, and will scold him. However, she can be the same way if she is excited enough.
