The Trigger Girls are essentially the mascots of Trigger as a whole. The leader is Miss Trigger, the red-haired girl.

Around 7-8 years ago, as part of Trigger's 5th anniversary, they aired the anime 'Space Patrol Luluco' where the protagonist, Luluco is dragged to serve as a space policewoman, the big twist behind the anime was that Luluco ended up really being Miss Trigger herself, essentially being an origin story for her as it were

While really theres no proof or anything, you could think that being the symbols of the company, the Trigger girls are goddesses themselves, and now, here in Npsg we have an actual goddess who is also a gun maniac like the Trigger girls are shown to be, which could imply Gunbitch or is one of them in disguise, or is the fourth girl.
