Amakan is the fandisk for Ama Ane (Otome and Natsumi) and Kimi wo Aogi Otome wa Hime ni (Hitomi and Rin). It also includes the standard version of Tsun na Kanojo Dere na Kanojo and an original story titled ‘Iinazuke wa Imouto-sama!’. Hayao lives with his true imouto Yuuna, but they don’t really get along. A beautiful girl who he had never seen before, Haruka, suddenly showed up and announced that she was Hayao’s imouto and also his fiancée. Yuuna opposed Haruka’s declaration since she had secret feelings for him. Neither would back down and it ended with Yuuna proclaiming that she was going to marry him as well.
