The chemistry teacher at Namori Middle School. She loves explosions. She can actually understand and hear Rise's quiet voice, and the two sometimes hang out, Rise helping Nana with experiments and such. Rise seems to have a crush on Nana, likewise, the art teacher of the school, Azuma Shihoko, seems to as well. The latter have known each other since high school, and Azuma is always asking Nana to let her draw her.
