Ren Miyaouji is the NPC created by Akira Oono of the series Maou-sama, Retry!.


Appearance, grace, brains, fame, all kinds of martial arts; no matter what high-class lady you search for - there’s no way you would be able to find a 16 year old girl like that. 


Ren gives the impression of being calm and cold like ice, but her heart is that of an incredibly kind person. Ren must have felt adverse feelings at the ruthless Game that was being promoted by the Grand Empire. 
Ren is also the most popular character in the game for the players. Even though she should be a hated enemy, she is loved. That’s how much of a person Ren is.


Ren was created by Akira Oono to serve as a boss in the Nightless Castle fortress. The best close-aide that could be said to be the one that has all Akira Oono ideals packed together.


Ren has less health than Kunai Hakuto, but it is scary how in every other status, she surpasses Kunai Hakuto. It is practically as if two last bosses existed, and in a lot of meanings she was an existence that made many cry.

Ren ability value has broken through the sky and has a status bar that surpasses Hakuto Kunai. However, because Kunai has many "decisive combat skills", so in terms of combat, even without a shield, the devil is far stronger. Although this is hard to believe, it is a fact.
