Shinsou Noise is the first game by a new collaboration company called Azurite, which was founded as a joint effort by Silky's Plus and Liar Soft.  In this case, Liar Soft provided the writing staff and Silky's provided the art and programming staff.  It is also fairly obvious that the planning wasn't done by the Liar Soft team, given the general style of the story, which is more in line with my experiences with Silky's Plus (and thus lacks the annoying conventions Liar Soft usually indulges in).
