Sensing the approach of his death, Senator Loriel Grinver of the Morigat Republic unexpectedly decided to hide the inheritance, which by law should have gone to his children. Greenver's sons and daughter searched through their father's entire estate, but the search led to nothing. And then it was decided to seek the help of a professional magician to cast the Summoning spell. As a result, a copy of the Russian schoolgirl Natasha Astakhova appeared on one of the Morigata islands. She got down to business, remembering how the original’s father, a police investigator, usually conducted the investigation.
