Cinderella Game (2016)

One of the participants (Ayame) tries to seduce Takimoto. He just laughs this off, and one of the Rats stops her as she is about to remove her bikini top.

Several scenes of girls fighting and trying to murder each-other, or at the very least, trying to steal one-another's cards.

Upon being eliminated or disqualified from the competition, the girls are executed via the necklaces they are wearing, which kill them via a lethal injection into their spines. This causes them to spit out blood, often onto other people, and instantly fall down dead.

The premise of the movie is girls being kidnapped and forced to fight one-another for their survival, lest they be killed. The entire movie plays this threat seriously, with the main character, Sana, constantly afraid and upset.
