The current student council vice-president and Nagahiro Sakiguchi's righthand woman. With the upcoming election, she is running to be student council president to uphold Nagahiro's ideals to keep the school somewhat free from the staff's wish for more work. Wana is nicknamed "Snow Queen" by many, though her actual personality is the exact opposite of what the name entails. She is sweet, upbeat, and extraordinarily friendly. Wana also has cat slippers and a framed photo of a cat, implying she is very fond of cats and cares for them greatly.

Spoiler

During the election, she is hit by a car. Luckily, it's nothing severe, but she will take time to recover and thus must tap out of the election. She is suspected of pretending an accident happened with the help of Yokuya Kinshirou, though Mayumi Doujima and Michiru Fukurou scrap this hypothesis after meeting her.
