IT'S THE END OF EVERYTHING! FINAL SEASON MEANS...FINAL JUMPING-ON POINT!! From across the galaxy, a terrifying alliance of alien warships enters our atmosphere. Luckily for the Earth's human population, they have a prison full of monsters that they can strong-arm, blackmail, and guilt-trip into battling for free. Inmates of both Kaijumax prisons suit up for the filthy, dangerous work of (giant) first responders, in a bid to lessen their sentences.
