It's the rookie Hayate's time to shine! A Martian terra-dome is under attack by weird worm-tentacle monsters, and as part of The Masters, a solar defense agency, it's her job to save the day. Equipped with a bodysuit that transforms any kind of damage into pleasure, she's near immortal- unless she is forced to orgasm until she loses her mind. That's up to you! Save the day and eradicate all the monsters, or lose to their sexual nature, willingly or not!
