To Revitalize the Demon King's Castle, I'll Debut as a Saintess

[Magical Girls + Idol Training]

The age of Demon Kings and Heroes has long since ended.

As the sixty-sixth Demon King, I've decided to turn my nearly abandoned Demon King's Castle into a tourist attraction and lie flat while collecting admission fees!

The problem is, that takes a huge amount of money.

There's a lucrative job right in front of me... transforming into a holy maiden who symbolizes love and hope!

Fine. For the money, I can accept turning into a girl... The job is to wipe out the calamity beasts wreaking havoc everywhere and protect the peace, right?

What? I also have to practice singing, dancing, and managing my expressions?

And promote myself by getting close with the other holy maidens?
