Demon Lord Amon's newest co-worker just so happens to be the hero fated to kill her--you can see where this maybe isn't great for workplace rapport.

What's more, when the hero Alystia transforms, she's an entirely different person...and a lot more prickly. It's the sixth course in a full-service meal of weird comedy!

Amon Patricia is a Demon Lord who ruled the land but after just barely escaping the Clan of Light finds her way to the Human World. Now there, she goes about searching for work and starts by looking at a family restaurant by the name of "Humming Dining." With her seemingly bottomless appetite and love of our hero's food will our hero be able to keep his sanity as he goes about making her an exemplary employee and fill her stomach?!

What happens when a family restaurant staffed by a Demon Lord, the hero fated to slay her, and a smorgasbord of curious characters faces back-to-back visits from a goddess, a doppelgänger, and a health inspector? "I won't allow them to destroy this restaurant! I'll destroy them!" Tuck in to the eighth course of this comedy feast to find out!

The holidays have come to Humming Dining! Halloween's up first - the perfect holiday for a Demon Lord. But the Boss seems even more thrilled than Amon, and commands her staff to wear costumes - the cute kind, of course! After that, it's the most wonderful time of the year...for home invasions! Highly suspicious of this Santa Claus, the "creep" who sneaks into people's houses, Amon decides to confront him on Christmas Eve - and it's up to Kouichi to make sure St. Nick makes an appearance.

Into this already strange establishment comes a cursed doll, plotting to absorb the power of the Demon Lord: "I sensed an evil power emanating from this establishment. I mean to make that power mine. And then...I will attain my true form!" Sit. Eat. TRANSFORM! A Demon Lord and a family restaurant come together to serve up a seventh volume of this comedy buffet!

For every demon lord, there's a hero destined to slay them! Luckily for Amon, this hero's got more than a few problems. Alys might be the chosen one, but right now, she's struggling even to get a good meal. Can Humming Dining's magic cooking restore her legendary powers? Or is she doomed to stay a stunted version of herself forever?

Ghost-girl Nukadoko is jobless and short on money. Good thing she lives in a restaurant! Can she make it as a server despite the fact that the customers can't see her?

It's time for a fourth helping of this hellishly delicious comedy!

 Lumachina has set out to reform the corrupted Church! Choosing to help her, Diablo finally makes his way to the Royal Capital. Even though a great battle against the Paladins looms ahead, Diablo is certain of his victory, for the new equipment he's gained from his Treasure Vault is overwhelmingly powerful by this world's standards. But before the battle can commence, the Church's believers stand in Diablo's way, powerless and helpless. Not wishing to fight them, Lumachina is imprisoned by the Church and falsely blamed for crimes she didn't even commit! The High Priest, the pacifist she is, accepts even this unjust treatment, but Diablo can't just sit idly and let that pass. "You fools who cannot even tell friend apart from foe—I have no reason to forgive your existences any longer!" Will Diablo's great magic annihilate the Church!?  This is the sixth volume of the adventure of an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!

After defeating the Grand Devil Belphegor, the Demon Lord returns from Hellion Territory to his home-away-from-home, the Village of Rabbi.

He had hoped to finally make space for some quality time with the friends he’s made in this world, but his well-deserved R&R is cut short when one of the four major political factions in Holylight sparks civil unrest.
