Double Decker! Doug & Kirill

The city-state of Lisvalletta is facing a crisis due to the emergence of Anthem, a highly addictive and powerful new drug that allows users to enter an Overdrive state where they transform into superpowered creatures. The police are struggling to contain this threat, leading the authorities to establish the Special Crime Investigation Unit SEVEN-O to tackle the issue. Kirill Vrubel, an average police officer, unexpectedly stumbles into a hostage situation involving an Anthem user in an abandoned warehouse after a chance encounter with a missing cat. He then partners with SEVEN-O detective Douglas Bilingam, earning a spot in the secret organization, which utilizes the "Double Decker" system of buddy cop pairs to handle the dangers of their work.
