The Heartless Capitalist Only Entertains Beautiful Knight Girls

When I woke up, I found myself in an unfamiliar world, face-to-face with a stunning girl who looked just like a succubus.

She called me "Master," but gave me a "tough" job: managing a dungeon.

This world was a little like the medieval West from the history of my previous life. Even the young knight ladies in the prime of their youth had rough skin from wearing armor and traveling so much.

So I made up my mind!

I'm going to build a hot spring dungeon!
