The Namegata Cryptid Research Institute was mainly dedicated to protecting Lake Kasumigaura's environment. One day, a letter arrives claiming 'We have captured Namegon.' The sender is an enigmatic group called NOSA. Investigating NOSA reveals that freeing Namegon requires disabling three of their systems. Dr. Asou entrusts a hacked manual to the rookie investigation team, assigning them to decode the passwords and save Namegon.
