Kana Yoshii (吉井香奈,Kana Yoshii) or "President" Yoshii is a character that often shows up in the K-ON! university chapters. She is only seen in the manga, since the restarted series is not animated. She knows much, being the president of the club, but likes to keep to herself. Yoshii has short hair and a fringe, and is usually seen with a bright, warm smile. At certain times, she can be quite scary too. Her personality seems to reflect off of Sawako Yamanaka, the Light Music Club supervisor at Sakura High.
She was proven to have a school uniform obsession, and secretly wears it in their clubroom, altogether with Chiyo. Chiyo states that she was happy to play together with Kana in their band, and hoping that one day, Kana will forget her obsession to school uniform.
