Jiangnan and Shimada seem to have fallen into a dead end in their search for the truth about the Aoyashiki incident.No matter whether in-depth investigation or careful analysis, no valuable clues were found.This made them feel extremely confused and frustrated, as if shrouded in an invisible fog.

They had suspected that the letter might be a prank, created by the laboratory girls who were trained at Jukkaido in search of excitement.But when the idea pops up in their minds, they quickly dismiss it.Because the content of this letter is too weird and too real to be a prank.

Just when the two were at a loss what to do, a nightmarish incident occurred in the Jukkakukan on Tsunoshima.This news was like a bolt of lightning, instantly breaking the peace in their hearts.They immediately decided to go to Jukkakukan to learn for themselves the events and details.

When they arrived at Jukkakukan, the sight before them made their hair stand on end.The entire restaurant was shrouded in darkness, as if swallowed by an invisible force.They walked into the library cautiously and saw a mess, with smashed items and scattered documents everywhere.

They began to carefully investigate the incident, interviewing witnesses and relevant personnel.After some efforts, they finally learned the truth of the incident.It turned out that this was a terrorist attack caused by a staff member in the museum.This staff member acted in such a crazy manner because he was threatened and intimidated by unknown persons.

Jiangnan and Shimada finally breathed a sigh of relief. It turned out that this incident was not related to the Aoyashiki incident.However, they also deeply realized that in this seemingly peaceful world, there are many unknown secrets and dangers hidden.They decided to continue their in-depth investigation, uncover more truths, and bring more light and justice to the world.
