The hero's rise? : Reborn as a Demon, I'll show you what a true Demon Lord is.

This isn't the usual story where a highschooler is chosen by gods to get stronger and defeat the demon lord to save the world..
Arizhel, a young man dubbed as the "True Hero" by the Laws of Universe who grew up serving his country with loyalty along with his friends.
Apparently being betrayed by the whole country and reborn at the Demon Continent is now trying to find out why was betrayed by climbing the rank of the strongest.

It sounds a lil bit crappy but im doing my best to write this, i hope y'all enjoy it.
