Inui Sana♀

Sana is a second-year student of Yuihime Girls' Academy and Airi's childhood friend. She makes an effort to welcome the male students from Kagamidai Academy, but later backtracks. Sana adores Miu and joined the Nuko Club because of her. She dislikes Shingo and often calls him "kuzu-mushi" (lit. trash worm). This is exacerbated when she notes the growing closeness between Shingo and Miu.

While she's a side character in the PC version, she became a heroine in the PSP port after taking first place in a character popularity poll for the game.
Later on the standalone game of Inui Sana's route was released in the FHD remake on PC.
In addition, newly written scenes, new CGs, as well H scenes are also added.
