While searching and dozing in a derelict warehouse, Kirill is thrust into a hostage scenario involving an Anthem user. By joining forces with SEVEN‑O detective Douglas "Doug" Bilingam, Kirill secures a position as the latest recruit of SEVEN‑O. With this clandestine unit"s assistance, he may finally attain his aspiration to be a hero.
