Synopsis
Hero reincarnated as Demon King's son vows to destroy kingdom from within as prince Zilbagias.
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. With the memories of his past life still intact, he vows to use his miraculous second chance to continue fighting—this time destroying the demonic kingdom from within as the Demon Prince Zilbagias. It doesn't take long for his mettle to be tested either, as passing as a young demon prince without blowing his cover proves to be quite a bit more challenging than he initially anticipated.

- 8 “I feel bad about the other reviews cuz this really was some good story that deserved so much more (even with its flaws). But I guess all good has to end and sometimes you'll just get ended abruptly...”
- 9 “For now, I'd say this is a great manga for sure. 9/10 Preliminary Review Story It's a cliche revenge way yada yada, I mean there are so many mangas already so you're expecting something original??...”
- 8 “8.5/10 I often wonder to myself on why I read so much trash — basic, cliche mangas that seem to have no bright side — but mangas like these point and blank justify all of the suffering I had to go...”
