Many stories have been told about Exo's Secret Detectives; even more stories remained the common property of the author and characters. Some cases that were classified as “Top Secret” for the time being, the past of the Kettarian Hunter and his senior comrades, the memories of Secret Investigation employees and a great many other events - all these stories have been waiting for their time for a long time. It would be possible to remain silent further, but the narrator does not want all these beautiful things that he saw - whether in reality or in a dream - to disappear forever, dissolve in the darkness, under his closed eyelids. Therefore, old friends gather together on neutral territory , in the Coffee Grounds tavern, which stands on the border between newborn reality and human dreams - between what has come true and what has not come true, in other words.
