ACS' first foray into the visual novel business (through its usual VN label VisuWorx). it's thriller novel based on a murderer with a butterfly motif (hence, "The Butterfly Halls"). yUi is actually a spiritual successor to it, taking place in the same timeline.

some useless trivia: did you know that some ACS arcade games in Japan use ACS' proprietary online service Amazenet?
