Summary
Notice : Volume 7 does not follow the time sequence. So the paragraph of the "Past" will have P in the beginning.

Prologue : To grant honors of the operations in Re-Estize, all of the custom NPCs and strong servants gathered in the Throne Hall. From the convention, Demiurge again emphasize their final object - taking over the world - and suggest to found Nazarick as an independent nation.

Main Story : Momon and Nabe stroll through the streets of Arwintar (the capital of Baharuth Empire) after their meeting with Fluder, to achieve their new object to demonstrate the force of Nazarick. Momon is very depressed that he should allow thieves to enter the guild headquarter, but as he understood that Demiurge's method is very effective and decides to follow the plan rather than reject it.

Meanwhile, Hekkeran returns to their residence and finds an moneylender bothering Imina, asking the location of Arche. After Roberdyck and Arche returns, Hekkeran asks about the moneylender. Arche conceded that she is indebted due to the extravagance of her parents. Considering Arche's circumstance - though they denied that they are worrying about Arche - Foresight decides to accept the quest from Count Femel, to investigate a mysterious large tomb. Taking money in advance, Arche expects that she can get away from her home with her sisters when she finishes the quest.

Four worker groups volunteered to the exploration: Green Leaf, Heavy Masher, Tenmu and Foresight. Count Femel provides them a best support, including special horse (Sleipnir) and adventurers for escort. The Darkness also go with them, and Momon asks the reason of their volunteer. The workers answer that they volunteered for money, and they thinks that the reward will be is worth their lives.

P. Fluder tries to dominate the legendary undead monster, expecting that the success will lead him to a higher rank of magic. Yet he fails again, and the Darkness visits Fluder. Though there was no reservation, Fluder decides to meet them, as he was interested in Nabe, known as a powerful magic caster.

The workers arrives at the tomb, and they find huge amount of treasure in the four affiliated tombs. Leaving Green Leaf as a scout, they go into the underground part of the tomb expecting lot more treasure. At the same time, Ainz returns to the tomb, leaving Pandora's Actor as his body double. Preparing to monitor the massacre, Ainz selects Foresight as his sparring partner. Now the ravages begin.

Green Leaf in the surface meets Pleiades, and they are forced to fight Nazarick Old Guarders. Though this fight was a test for pursuit of fleeing invaders, they were too weak and all of them are defeated even without deployment of other servants. Heavy Mashers becomes exhausted by the endless waves of monsters. After escaping from deadly traps of undead, they meet six elder liches and run away from them. During the flight, a trap transports them. Gringum and thief are eaten alive by cockroaches of Prince of Terror, and at least one of them becomes a toy of Neuronist. Tenmu encounter training lizardmen and Hamsuke. Hamsuke challenges Erya to a duel to test its own progress as a warrior. Erya is beaten and killed by Hamsuke's martial skill. Foresight are also transported by a trap, moving them to the Amphitheatrum. Hekkeran tries to deceive Ainz that he came to the Nazarick by the order of Ainz's colleague, but Ainz see through the lie and becomes really upset. After fighting with Foresight as a warrior, Ainz decides to stop playing and reveals his true power. Other members tries to earn some time to allow Arche to run away, but all of them are instantly beaten by Ainz, and Arche is also killed by Shalltear.

After checking that the defense system of Nazarick works properly, Albedo suggests Ainz to establish a secret surveying team to search other guild members. Ainz approves the idea. (Though it seems that Albedo's true objective is to annihilate all other guild members.)

P. Meeting with Fluder, Ainz and Narberal show him their true power. Fluder immediately swears allegiance to Ainz.

And this is how the invasion was occurred. Fluder lied to the Emperor that he found the tomb by his magic, and the Emperor used Count Femel to investigate the tomb, to avoid the responsibility of invasion. But as the invasion itself was the plan of Demiurge, Aura and Mare visits the imperial castle with dragons and threatens the Emperor if he does not apologize for the invasion, then they will destroy the whole empire. So the Emperor decides to talk with them.
