Ririsu is funny Nice adventure game with many choices of story development of the individual characters. The whole story is decorated with beautiful CGs and although not much is understood by the Japanese, we understand yet the story based on the facial expressions and the behavior of charas on one's own decisions.
I bought the double pack, and could thus play both stories.
For those who do not already know T-Wave is the first part and next relation is the second part of the story.
