Histoire
The hero Alexander and his comrades unleash a daring raid on the Demon King’s castle, intent on assassinating him and bringing an end to the war against the darkness in one fell swoop. However, the raid goes awry when his party is effortlessly decimated by the Demon King’s overwhelming power. But death is not the end of the road for Alexander, as he is reincarnated two years later as that very same Demon King’s son.
