Kimi ga Ita Ano Hi

Our hero has come to a small, ocean side clinic as an intern. Here, he is faced with Kouta Suzukaze, a girl who has been hospitalized with a fatal illness that cannot be cured or even treated with modern medicine. Due to her imminent death, she has closed herself off from the world. Is it possible for you, as an intern, to help her open up? You will get to meet Kouta's rival and little sister, Komichi, along with the hot and seductive Dr. Ryoko Nagauchi. You will be able to hear full-voice narrations and enjoy every scene in full-CG animation.
