In Kana Imouto, you have a sister who's two years younger than you named Kana, who has been ill all her life, spending more time in the hospital than at home. In the past you felt jealous of the special attention Kana received in your family, though in recent years you've come to treasure your younger sister instead, wanting to do anything to help her. Though life is never simple, in the end all you want to do is find a way to save your dear little sister. The reason is... you love her.
