A unique transmigrator, mistakenly believing himself to be half an "assassin" at birth, thus actively chose the assassin's path... "I was so stupid, so very stupid... I only knew that my traits matched the assassin's path, so I actively chose it. I didn't know there were other paths with similar abilities..." The assassin's path—not a good choice, but not exactly bad either. The Fifth Era—the best of times, and the worst of times. A chaotic and insane world, yet it shines with the light of humanity and hope. This is the story of a protagonist saving himself and averting the apocalypse.
