Humanity went into shock when they first learned of the existence of aliens and there were even rumors of an invasion; however, because their bodies look almost identical to humans as well as the fact that they lack hostility, this allowed humanity to get used to their presence and eventually accept them as part of their daily lives. Chigusa Tomoki is a high-school freshman who lives alone in an apartment because his parents are working overseas. However, the real estate agent accidentally double booked the apartment and Tomoki ends up sharing the room with a gorgeous female alien, Yuuri Myua. Myua, comfortable with her body, loves being naked, which bothers and excites Tomoki at the same time. Myua is here for a secret mission regarding Tomoki as his DNA is an extremely rare strand, which gives him the ability to mate with any species of aliens. If that wasn’t enough, his offspring would have incredibly high abilities.
Tomoki has to deal with a more than eager roommate and aliens after his DNA. As if living alone as a teenager wasn't hard enough.

1. Gantz
Thought your life was bad? Sometimes, death is worse. There is no salvation, peace, nor god waiting to receive you into their care. But wait, a god? Maybe you are talking about that big black ball stuck in the room with you. Now you are thrown into a game, fighting green aliens and robot monsters for the chance to survive.
When Kei Kurono is killed, he thus finds himself caught in such a game; a test of his skills, morals and will to survive. His life is not his own, his death spat and trampled upon over and over again. What happens if he does not listen? God knows.
A word of warning: Gantz is not for the faint-hearted, but neither is it as simple as it looks. Gore, rape and violence is rampant, as are portrayals of greed, violence, and all the ugliness that one sees in society today.
Gantz has finished publishing and it has 383 Chapters. It is also Known as: GANTZ, Gantz/Osaka
