Full Summary
The Roble Holy Kingdom is a human nation which occupied the peninsula to the southwest of the Re-Estize Kingdom. It is a highly religious country, led by a Holy Queen Calca Bessarez, who could use divine magic and who was closely affiliated with the churches. They are not as religiously-oriented as the Slane Theocracy due to their religious differences. The entrance to the peninsula is a Great Wall, it is built to withstand invasions from the Demi-Human Tribes of the Abelion Hills located at the east of the Holy Kingdom.

Somewhere in the fortified station in the Great Wall, Orlando Campano, a corporal of the Holy Kingdom's Army waited for his shift to be over. Platoon Sergent Pavel Baraja arrived to get Orlando's shift report, but Orlando wanted to tell his superior something before the shift change. Orlando tells Pavel that he wanted to go on a warrior's pilgrimage and wanted to quit his position. Pavel didn't stop him and tells him that he should have gone on his warrior's journey earlier or because there are no more demi-human attacks. Orlando tells Pavel that he doesn't enjoy slaughtering demi-humans and wanted to fight strong people. He also asks Pavel for the details about the death of Gazef Stronoff whom he heard had died in battle. Pavel informs him that the higher-ups are debating about how that's going to affect the surrounding countries. Pavel also inform Orlando how Gazef was killed by the Sorcerer King in a duel and that the latter also massacred an entire army. The reason why Orlando wanted to go a warrior's pilgrimage was to visit Sorcerer Kingdom. Pavel stated that he was going to miss Orlando when the bells suddenly rang, which meant demi-humans were sighted.

Additionally, Pavel noted that the enemies consisted of multiple races alerting him that this time they were a united front. As they're preparing for an assault, a single figure steps forward from the assailants. He introduces himself as Demon Emperor Jaldabaoth, and states his intentions for the Holy Kingdom. Pavel and his archers fire at him, to no avail. The demon then drops a meteor on them, killing all of the rangers. Demiurge, satisfied with his actions, turns to return to his unwilling subordinates. He stops for a moment to kill Orlando, who tried to attack him, before commanding the demi-humans to attack the now devastated wall and the invasion of the Holy Kingdom begins.

Once they've learning about the invasion of the Holy Kingdom per an army of demi-humans, Calca Bessarez the Holy Queen issued a mobilization order through the entire nation. During a private meeting with Remedios Custodio and Kelart Custodio in the city of Kalinsha, Calca pondered the future of her nation. Despite reassurances from Remedios that the Holy Kingdom would survive Jaldabaoth's onslaught, she was worried about the financial aftermath of the Holy Kingdom. Their conversation was suddenly interrupted when Jaldabaoth himself invaded and attacked the city. The queen and her advisers went to confront the Demon Emperor.

Among the arrivals, Remedios and her Paladin Order were the first to arrive at the location in order to engage Jaldabaoth in battle. She tried to defeat the demon alone only to have him avoid her strikes. Later on, Calca and Kelart arrived at the site together with adventurers. Calca tried to parley with Jaldabaoth, but the demon revealed that he only wanted to survey the city, to see if there was a being in the Holy Kingdom that could match him in power. The demon wishes to ensure his mission is a success this time around and not to repeat his failure again like last time in the Re-Estize Kingdom.

When Remedios is fully buffed with magic, she began attacking Jaldabaoth offensively to no avail and was successful in knocking the demon away into a building. According to Remedios's instincts however, told her that the demon couldn't have been defeated so easily and that her attack should not be able to knock him back that far away. She then orders Calca to use the Ritual of Holy Fire in order to make sure he is dead for good. Before Remedios and the others could speculate further, Jaldabaoth emerged from debris in a more terrifying demonic form. The paladins attempted to fight him, but were stunned to learn that the demon's new form gave him some sort of immunity to their weapons. Remedios charged at the demon with her holy blade, but Jaldabaoth merely teleported to where Kelart and Calca stood. In order to make the people present on the scene faced utter despair, Jaldabaoth decided to use the Holy Queen as a bludgeon. As well as signaling to them that he has summon a meteor from the sky, which as a result, crashes down on the city wall and destroy it.

Scene changes to Neia Baraja, a squire of the Holy Kingdom Liberation Army, walking through the streets of the Royal Capital of the Re-Estize Kingdom. She notes the heavy mood of the citizens within the Kingdom and thinks it is because they were defeated in battle not long ago. She later proceeded to the inn, where the ambassadorial delegation is hosted. Once there, Neia reports back to her superior Remedios that the nobles she tried to contact would not be able to receive them due to the lack of time. Remedios believes that this failure is Neia's fault. Gustav however came to her aid, explaining to Remedios that other nobles refused their requests for the same reasons. At the same time, he also requested for Neia to be present with them in the delegation meeting with Blue Rose.

During a meeting with the adamantite team Blue Rose, the delegation came to realize that no help would come from Re-Estize Kingdom, or it's nobles, being that the only person able to defeat Jaldabaoth, Momon, has swear fealty to the Sorcerer King Ainz Ooal Gown. Upon realizing that Momon is now a part of the Sorcerer Kingdom, the delegation then proceeds to head to the Sorcerer Kingdom and seek him out.

While journeying to the Sorcerer Kingdom, the delegation came across a strange mist and later a Ghost Ship patrolling that country's borders. When the delegation reached E-Rantel, the capital of Sorcerer Kingdom's capital, the group was impressed to see that the statues are being used as the gates of the city. What awes them even further was the appearance of the Frost Giants tending to it.

Upon entering the city, the delegation was astonished by the various races that inhabited the city after its conquest by the Sorcerer Kingdom. Walking towards the Shining Golden Pavilion, the party came across a trio of dwarves along the way. After questioning them about the state of what's happening in this city, the envoys are surprised that the dwarves were technical advisers that came from the Dwarf Kingdom itself and that they were using the Undead to pave roads.

One day after arriving at E-Rantel, the delegation was granted an audience with the Sorcerer King, Ainz Ooal Gown. The delegation is surprised that they are allowed to bear their arms in the presence of the Sorcerer King. Silently to themselves on the other hand, they disdain the simple and unadorned throne room of the Sorcerer Kingdom. During the exchange between the two parties, the Sorcerer King could informs the delegation that he could only provide help within four years time. Due to the unwavering insistence of Neia, Ainz was delighted and further cut down the time for aid into two years instead.

After the negotiations had finally concluded, the delegation returns to the inn. Remedios started to scold the Neia for interfering in the negotiations with the Sorcerer King. However, Neia counters back, saying that her effort had shorten the time even further than neither Remedios or Gustav were capable off on their own. After a series of arguments, Neia went outside the inn to cool off her head, but then suddenly, she hears an invisible voice coming from behind her and it directed the girl towards a back alley. Entering the back alley with nobody around but the two, the identity of the man speaking to her was soon revealed to be the Sorcerer King, Ainz Ooal Gown himself. The Sorcerer King came to talk to her personally as the undead stated that he has another proposal for the delegation. Reasoning with Neia, he wants to carry their second meeting out in secret without his servants around there with him to take part and asked the young squire to help him get into the building in secret, to which she accepted without hesitation.

With the meeting taking place, Neia and the rest of the Paladin Order listened to his proposals and after deliberations have chosen that they are acceptable. Gustav scolded Remedios for accepting the proposal of the Sorcerer King so easily without considering the consequences. He reasons with her that if something bad were to happen to the Sorcerer King's life, then the undead controlled by him may end up being uncontrollable after his death and could cause havoc. After his explanation, Remedios told him if that did transpire, who would stand to gain more from the conflict than the Holy Kingdom, since they perceived both demons and undeads as enemies of mankind. To carry out their plan accordingly, they've ordered Neia to act as Ainz's personal guard as well as to keep a close eye on him.

In a carriage of propriety of the Sorcerer Kingdom, Neia and Ainz travel towards the Liberation Army camp. During their jorney Neia came to the realization that the Sorcerer King, despite being an fearsome undead and radiates the grandeur of a king, was extremely magnanimous, acting as an ordinary person from time to time. In order to take down the heavy mood in the carriage and make Neia more comfortable, Ainz ask her what kind of jobs squires do, and what they entrail. He ask her the reasons for her to choose to become a paladin, which she explains is because her mother being one. Neia admits have no talent with swords, having talent with bows, like her father. She complains about her eyes, which are from her father and talks about stories of her childhood. During this conversation Neia tells Ainz that her father died defending the wall against Jaldabaoth, and that her mother is more probably dead. In order to compensate, Ainz lends Neia a Bow, telling her that it's the product of dwarven runecraft.

Arriving at the Liberation Army's hidden base Ainz discover that the army faced several issues that needed to be addressed such as a new base of operations, as it was believed by Ainz that the current location was compromised. In addition, their food supplies were running low and winter was nearly upon them.

To increase the strength of the Liberation Army, Remedios put forth a plan to liberate the captured Holy Kingdom citizens from the nearby prison camps. At the same time, they would confiscate any food supplies that the demi-humans possessed and continue onto the next a nearby occupied city. It was believed that if the Army managed to liberate high-ranking individuals and members of the Royal Family with ties to the South Holy Kingdom, it would force the nobles in the South to take action. As conscription is being used in the Holy Kingdom, most of the men are battle-ready, so they are hoping those that might be freed may join their ranks and help further recapture other cities and villages.

When questioned about this plan by Gustav, Ainz points out that the prison camps probably don't have much food, much less able ready battle man, because of malnourishment.

The Holy Liberation Army marched on their first target, a village that turned into a prison camp by the Bafolk and was located furthest from the Army's hidden base. The resistance force eventually freed more towns and settlements, however, the food supplies were not nearly enough to sustain the Liberation Army and it recruits. They eventually found the source of the food to be located in a small city ruled by Buser, which they manage to liberate with Ainz's help.

After the liberation of the city, the Army discovered that one member of the royal family was interned there. Prince Caspond was given command of the resistance forces and held an audience with Ainz Ooal Gown.
