The villain specifically demands five adolescent girls who have just lost their virginity and has his underwater ninja zombies kidnap them against their will to use as human sacrifices. The ninja zombies openly discuss and express their strong desire to rape these captive teenage girls, though the doctor orders them to wait until after the ritual. There are also elements of sexual harassment through non-consensual grabbing and abduction during the kidnappings, along with crude, objectifying dialogue. In the downer ending, the protagonist (Jess), cursed with unbearable full-body itching that can only be relieved by having sex, attempts to have sex with the zombified corpse of his own girlfriend without her permission in order to cure the curse placed on him by Mr. Miyagi. This attempted act would also constitute necrophilia because she is already dead and reanimated as a zombie.
