There is a post-credit scene that leaves the story on a cliffhanger.
SPOILER: The intro title sequence offers major clues to each character's origin and plot points in order of appearance. It's revealed through hints of imagery that Kioma is an orphan, Franky was formerly an LAPD detective, Ruby is a Texan lawyer, Maxi a former 14K Triad, etc.
Easter egg: the Eye of Son symbol can be seen in the noise distortion of the Rebel Rated logo at the very start of the film (hidden in a frame).
