TEKKEN 7 Famitsu Site Opens - Story Background for New Characters Revealed
Famitsu has opened a dedicated page for their coverage of TEKKEN 7 during TGS 2016 and they have the story background for the new characters in the game. It details the basic overall lore for the characters and gives you an idea why they've entered the King of Iron Fist Tournament 7. Gonna add a quick note that usually when you read character background lore they have a flavorful style of text to them but I'm going to unofficially translate these bios until they are released officially in English. You can read the source of the backgrounds in Japanese over on Famitsu Tekken 7 page.
