NO FATIGUE: The Rebirth Tale of a Man Who Can Fight for 24 Hours

The protagonist exits an arcade and encounters a random stabbing incident. While trying to help a female high school student, he struggles with the attacker and ends up fatally stabbing him. A police officer who arrives at an unfortunate moment mistakes him for the culprit and shoots him dead, ending his 30-year life... or so it should have been. However, a goddess from another world, taking pity on the protagonist, decides to reincarnate him into that world. The condition is that he must defeat the random stabber who is also being reincarnated into that world. Thus, the protagonist is granted only the skill of 【No Fatigue】—a state in which he experiences neither mental nor physical exhaustion—and is reincarnated into another world. ※ The book versions of volumes 1-3 are currently available from Overlap Novels. Updated 18/10/5: I have begun serializing a new work with a similar concept. I would be pleased if you would read it as well. 『NO STRESS: The Reincarnation Story of a Man Who Can Endure 24 Hours』 https://ncode.syosetu.com/n8387fa/ ※ Also posted on Kakuyomu.
