Inyoku Tokkyuu Zetsurinou

• Both are parody hentai x mecha anime where the mecha gets power from sexual act between a boy and a girl. (Masou Gakuen HxH is a border line hentai anime wherelse Inyoku Tokkyuu Zetsurinou is a full on hentai anime) • As for hentai standard both are prity creative and quite funny other than being horny ofcourse.  

When the world is in danger, the government created a giant robot/mecha as new weapon in order to maintaining security & stability using new source energy as main power. - ERO-Particle as Daimidaler main power - Orga Stone as Zetsurinou main power However, to activating this new power, MC must perform some erotic/hentai scene inside the cockpit to achieve some level where MC can release his/her true strength. Even this condition done by duo couple not alone. - Kyouko x Madanbashi (Kenze Robo Daimidaler) - Nozomi x Unnamed-Male-MC (Inyoku Tokkyuu Zetsurinou)  

Both titles are hentai genre, and are about heroines fighting against evil with power but the power requires constant pleasure to acquire it. The story isn't anything complex, and is easy to follow along. It can be weird at times, but there are many comedy elements, so both titles are as light-hearted as it can get. 

Dear Lord, what do we have here. Two hilariously bad titles, both which use rather, um abnormal sexual scenes for comedy; or least that's what it comes across as cause they're just that bad. Many cannot unsee moments. I really wish to say what they are, but will refrain from doing so as i wish for the shock factor to be as high as possible for you virgins.
