The Blackburn Residence (カーティス邸, Kātisu-tei, lit. "Curtis' house") is a location in killer7. It is the setting of the second half of Target03: Encounter. As its name suggests, the property is the home of feared assassin and human trafficker Curtis Blackburn, as well as his protégée AYAME. Its location is simply given as 'Mt. Area, Seattle' on the world map, although its position on the map suggests it is situated somewhere near the real-world Mt. Rainier National Park.
