Chris was like any other protagonist someone who didn't belong and was rejected by society, spending every day working himself to the bone by working one construction job to another. That was until he was killed in a freak accident, awakening from his death he finds himself in another world in a foreign body tasked with defeating the demon lord and his mighty army.
