My source just alerted me to this. The main heroine gets chloroformed and tied to a pole to get sacrificed to a giant... Anteater? Porcupine? He thinks it's either a wolverine or a mole (pretty sure their hair isn't that think but whatever ).
Episode 22, the pink haired alien ninja girl is rope tied again and this time blindfolded for a one of those "beat me in a duel and you can have the girl back" scenarios.
Episode 32 continues where last episode left off, DiD scene continues around 2:15. Then she's rope tied again around 6:10 then cross tied around 13:24.
