The second adventure in the career of the Shinseigawa Detective Office follows the mysterious happenings in a building known as "Kairōkan". The eccentric former chairman of a building company invites a group of seven to Kairōkan for an inauguration ceremony, but when he fails to show up one of the other party members winds up dead. With only a limited set of suspects and a mysterious set of clues, detective Ryōsuke Kibukawa has his work cut out for him. This mystery visual novel is menu-driven, with players making their choices from a set list of actions; Kibukawa's investigation is mostly driven via dialogue.
