18+ "Koko wa Makasete Saki ni Ike!" wo Shitai Shinitagari no Nozomanu Uchuu Gekokujou @comic

Nao has had it rough. His girlfriend dumped him and ran off with another man, and now his life has lost all meaning. As he contemplates suicide, he catches sight of an advertisement for Space Force—a military force dedicated to protecting the planet from extraterrestrial threats. Finally, a sign that maybe he can do more with his pathetic existence!

Without a moment's hesitation, he joins the force with a simple plan in mind: he'll sacrifice himself for his comrades after a suave line and be free. Except...Nao is too good at this job! Like, really good—there's no way he'll die on his own at this rate! Can Nao find his sweet release, or will he become a hero and have to live with it?
