Description:

Wishing she would live up to the ideal, Kanzaki Nao's father named her thusly for “honesty”. Nao has more than lived up to her father's wishes—even exceeding them and earning the label of "a foolishly honest girl". This makes Nao the least qualified candidate for the high stakes 'Liar Game', where winning requires deceiving the opponent out of their money and losing means receiving massive debt. However, that doesn't stop a box containing a hundred million yen in cash and a card informing her of her participation in the game from arriving at her doorstep, nor does it stop her from being promptly tricked out of the entire sum of money. Upon hearing that a genius swindler, responsible for the bankruptcy of a major corporation, is being released from jail, Nao goes to the swindler, Shinichi Akiyama, to enlist his help. With that, the two are drawn into the dark, greed-filled, and deceptive world of the Liar Game. (Source: MAL Rewrite)

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. (Source: MAL Rewrite)
