Have you heard of Hell Correspondence? Those with a powerful grudge may only access this mysterious website at midnight, allowing them to enter anyone's name and have that person be ferried straight to hell. Ai Enma, the Hell Girl, will not judge whether or not the chosen target deserves punishment; she will merely exact revenge on them for you. Not much is known about this young girl other than that she swiftly carries out her tasks with the help of three straw dolls. There is just one catch, however—as payment for carrying out such a request, the user must condemn themselves to an afterlife in hell. [Written by MAL Rewrite]

Shinichi Kanou is a shut-in otaku with a vast knowledge of anime, manga, and video games. One day, after applying for a job in hopes of escaping his secluded lifestyle, he is kidnapped and transported to the Eldant Empire—a fantasy world filled with elves, dragons, and dwarves. Trapped in this strange land, Shinichi is given an unlikely task by the Japanese government: to spread otaku culture across the realm by becoming an "Otaku Missionary." To accomplish his mission, Shinichi has the full support of the Japanese government, as well as the half-elf maid Myucel and Princess Petralka of the Eldant Empire. Together with this ragtag bunch, he will overcome the obstacles of politics, social classes, and ethnic discrimination to promote the ways of the otaku in this holy land. [Written by MAL Rewrite]

Although Jirou Horikoshi's nearsightedness prevents him from ever becoming a pilot, he leaves his hometown to study aeronautical engineering at Tokyo Imperial University for one simple purpose: to design and build planes just like his hero, Italian aircraft pioneer Giovanni Battista Caproni. His arrival in the capital coincides with the Great Kanto Earthquake of 1923, during which he saves a maid serving the family of a young girl named Naoko Satomi; this disastrous event marks the beginning of over two decades of social unrest and malaise leading up to Japan's eventual surrender in World War II.

For Jirou, the years leading up to the production of his infamous Mitsubishi A6M Zero fighter aircraft will test every fiber of his being. His many travels and life experiences only urge him onward⁠—even as he realizes both the role of his creations in the war and the harsh realities of his personal life. As time marches on, he must confront an impossible question: at what cost does he chase his beautiful dream?

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 is 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. [Written by MAL Rewrite]
