Crash Keys is seeking investment partners to advance original projects and build its business foundation.

Kotaro Uchikoshi Reveals 999 Character Seven's First Name 17 Years Later

Kotaro Uchikoshi, director of 999: Nine Hours, Nine Persons, Nine Doors, revealed that the character known as Seven actually has the first name Six, making his full name Six Seven. The reveal came 17 years after the game's 2009 release, in response to a fan question on X. Uchikoshi said the name references the 2025 "6-7" trend, which originated from basketball players and a viral video. The reveal is clearly a joke rather than a canonical lore addition.
