A man covered in blood can be seen kneeling in the middle of a devastated battlefield."Who would've thought that the brightest hero of humanity is colluding with the devils."Suddenly, the seemingly lifeless body of the man flinched. He laughed hysterically and said. "I get it now... Jealousy, envy... humanity will ultimately destroy humanity."The man closed his eyes, seemingly ready to accept his fate. But as the darkness started to devour his consciousness. He suddenly heard a faint, ethereal whisper. "Embrace the darkness."And when he opened his eyes, he found himself back in time. Will he stay on the path to becoming a hero to protect humanity, or will he be the reason for its destruction. NOTE: There are two titles: the first is Everybody wanted to be a hero, so I became the villain, and the other is The Hero's Spiral Into Insanity.
