Description

Earth is being invaded by the evil organization, Dai-Lust.

After summer break, there is a new transfer student in your class, Kouenji Sayuka. Sayuka is your childhood friend, but somehow she has no memory of you at all, and out of nowhere she now has a younger sister, Kouenji Madoka. The next day after school, an evil organization known as Dai-Lust began invading Earth. You witness Sayuka masterbate and transform into a warrior named Escalayer who then defeat the bad guys.

Later, Madoka explained to you that Sayuka's consciousness has been transferred to a bio-body (which caused her to lose her memory), which has great fighting capabilities, but requires energy from sexual excitement to charge up. Madoka (who turns out to be a support android) threatens that if you do not help them she is going to distribute throughout the world the love letter you wrote to Sayuka when you were in kindergarden.

So begins the fight to save the world.
