Many stories about the Secret Investigators from Exo have been told; even more stories have remained the common heritage of the author and the characters. Some things that have been buried until now under the stamp "Top Secret", the past of the Kettarian Hunter and his senior comrades, the memories of the employees of the Secret Search and a great many other events - all these stories have been waiting for their hour for a long time. It would be possible to keep silent further, but the narrator does not want all these beautiful things that he saw - whether real or in a dream - disappeared forever, disappeared in the dark, under his closed eyelids. Therefore, old friends gather together in neutral territory, in the tavern "Coffee grounds", which stands on the border between the newborn reality and human dreams - between the come true and the un come true, simply put.
