Double Decker! Doug & Kirill

is a 2018 Japanese anime television series produced by Sunrise, which premiered on Tokyo MX from September to December 2018.

The series was created by the same animation staff who produced Tiger & Bunny, as the next instalment to the studio's "Buddy" theme series, which led to initial confusion among the audience is the series was a T&B spin-off. As of current news, there is conclusive facts detailing the connection between Tiger & Bunny with Double Decker! Doug & Kirill in-universe, hence the two properties are currently considered separate pieces of media.

Plot
In the city-state Risvaletta, while people go about their tranquil everyday lives, crimes and illegal drug trafficking run rampant. Above all, a dangerous, highly-fatal drug named "Anthem" is casting a dark shadow on the streets. The "Seven-O" special criminal investigation unit whose speciality is to supervise the Anthem investigation, institutes a "Double Decker System" policy of forming groups of two investigators, and all members are given nicknames.

One team consists of the veteran investigator Doug Billingham accompanied by the rookie Kirill Vrubel. This unconventional duo combines an aloof veteran detective who is hard to get a read on, and an inexperienced detective who is a little too eager.
