Kill the Past is the collective term for a number of related video games directed by Goichi Suda, also known as Suda 51. Not only are these games often thematically similar, but they also feature a number of recurring trademarks, for instance: severed heads (sometimes in paper bags), the death and resurrection of playable characters (as well as the meaninglessness of death in general), the Moon, assassins, the medium of television, and occasionally even recurring characters. The main theme in "Kill the Past" titles is the necessity for their protagonists to destroy relics of their past that burden and prevent them from moving forward. Oftentimes, characters find themselves at odds with previous events in their lives that must be confronted head-on for them to be at ease.
