Dungeon Create

I thought I would wake up in my own bed, like I always do...

But instead, I found myself awakening in a dusty cave, with a peculiar young girl staring at me from the side!?

"Good morning! Nice to meet you, Master—!"

"You have been chosen by this dungeon as its master!"

"Join me in managing the mightiest underground dungeon!!"

I have no choice but to obey that girl,

and embark on the journey of dungeon management...
