A trailer for next week's PC eroge Imouto ga Boku o Neratteru, developed by ALL-TiME and releasing in Japan this April 27. The game's protagonist Keita has three imoutos (little sisters) - Erina, Tomoka and Yuzu - whom he lusts after. At the same time, the oldest imouto Erina had fallen in love with him, since he had always been by her side. However, she felt that there's no way she could admit to having these feelings and continued to hide them. One day, a girl named Saori joined their family via their father's remarriage, becoming their older sister. She was beautiful, kind, smart, great at housework and cooking - perfect in every way. Saori quickly became close with his imoutos, and Erina found someone that she could confide in. Following Saori's plan, his imoutos begin to launch a full-on assault on him.
