Otaku in 2200 Ad, Part 3

Oota and the crew got their asses to Mars and they've found themselves out of the frying pan and into the fire. The origins of sextasy have been discovered and now everyone is after its unlimited power with ambitions to control the galaxy! Only Oota and his number one idol, Anna, can save the future, but they have to go back to the past to do it. However, even if they return home, after discovering super duper mega boobs that turn you into a human paizuri, and holodeck sex that fulfills your every fantasy, can Oota even adjust back to the present day! ?
