Ever since the old Art Club president, Sana Sunomiya, resigned due to her graduation, her sister, Hana, has taken her spot. Unfortunately, Hana is a direct copy-and-paste to her sister. She's as equally serious and stoic, and both enjoy being in the nude.

Hana: ".. Senpai. I have come to stop you from proceeding on this date. I will protect Senpai's love.."
