Lazy Dungeon Master: Volume 12

Keima Masuda is a Dungeon Master whose goal is to live without working. He has just returned from the imperial capital, and on the other side of the mountain he finds a new town that was not there before.

The new town copies his own and has its own inn. Keima expects fewer customers and less work, which suits him fine. Instead, more customers keep arriving.

One rival draws attention with something called an "Artifical Dungeon". Keima has to face a copy of the thing he does best, and the question is how a fake measures up against the real one.

The High Priestess of the Holy Kingdom turns up as well, and her devotion to Keima has not cooled. She treats his sharp insight as proof of their bond.

This is Volume 12 of the series. The tone is comic, built on Keima's wish for idleness and the trouble that keeps landing on him anyway.
