Royal Army (王国軍) was the main military force of the Re-Estize Kingdom. It pooled the combined might of the various feudal lords to combat the annual incursions of the Imperial Army.

The army was completely destroyed during the final war between the Re-Estize Kingdown and the Sorcerer Kingdom.


The Royal Army was mostly composed of a militia. Its soldiers were mostly just drafted peasants, they received weapons to wield from the government, were given no armour, and were barely trained. The Kingdom usually levied two-hundred thousand men to fight the Empire, but could levy more if necessary.

Ramposa III sent Gazef Stronoff and his group of warrior troops to investigate and eliminate imperial soldiers who were raiding several villages in Kingdom's territory.[1] It was around this time that Gazef came face to face with a mysterious magic caster who made his presence known by the name of Ainz Ooal Gown in Carne Village.[2] With the aid of the magic caster, the group was able to survive their battle with the Sunlight Scripture.[3]

The Royal Capital of the Kingdom was suddenly surrounded in a wall of flames.[5] It had come under attack by a demon known as Jaldabaoth and his army of demons, who came to the city to look for a powerful magic item.[6] A large coalition of the Kingdom's adventurers and soldiers were brought together by Princess Renner and Lakyus Alvein Dale Aindra. Not only that, but they were receiving aid from the King of Re-Estize himself, Gazef and his Warrior Troop. In addition to that, Marquis Raeven brought his private troops along to join the resistance in stopping it.[7] They were able to successfully defend the capital from facing any further destruction by the demons who are forced to retreat thanks to the effort of the adventurer group Darkness triumphing over Jaldabaoth.[8]

The Magic Caster of Destroy Arc[]

The Royal Army began prepping up for their annual war with the Baharuth Empire at the Katze Plains. However, the Empire this time, had decided to form an alliance with Nazarick in order to acquire the territory of E-Rantel for the creation of the latter's newly-founded kingdom, the Sorcerer Kingdom. With the war looming closer as two months pass by, the Kingdom then decided to dispatch an army of 250,000 men over to the Katze Plains where the war would take place.[9]

Meanwhile, an additional 5,000 troops, led by Crown Prince Barbro, headed to Carne Village to gather information about the mysterious magic caster Ainz Ooal Gown. However, talks with the villagers broke down, resulting in the force being run off by the village's Demi-Human inhabitants and survivors finished off by an additional force.[10]

When the war kicks off first with Ainz Ooal Gown's successful casting of his super-tier spell, the tide of the battle was already against the Royal Army's favor. Due to the effect of such potent spell used on the Royal Army, most of their soldiers were devastatingly wiped out by the Sorcerer King. Meanwhile, at the same time, five Dark Young were conjured on the battlefield, appearing as a result of the tremendous amount of lives among the Royal Army sacrificed which partly contributed in making the summoning occur. Although the massacre was still going on by Dark Young creatures stampeding people to death, it can be noted there are already a casualty of 70,000 soldiers from the Royal Army who instantly died from the spell Ainz had cast onto them.[11]

By the time the massacre at Katze Plains came to an end, the death tolls for the Royal Army were reported to exceed more than 180,000, with more missing by far. This horrible turn of the event left the remaining soldiers mentally scarred and unable to live normal lives any more.[12]

According to the information acquired by the Slane Theocracy's Six Cardinals, with just the use of one spell by the Sorcerer King, it was enough in managing to kill over half of the Royal Army. During this battle, they note how the Kingdom mobilized 260,000 men to the battlefield. They speculated that half of the Royal Army would have at least 130,000 people as part of the many casualties in the Katze Plains because of it. They described Ainz's 11th tier spell to have wiped out a specific side of the Royal Army which are estimated to be over 80,000 deaths.[13]

The Paladin of the Holy Kingdom Arc[]

At this time, many people living in the Royal Capital were still depressed over the Royal Army's devastating defeat at the Katze Plains.

After most of the Northern Holy Kingdom had been conquered by Jaldabaoth, the Holy Kingdom Liberation Army sent a delegation to the kingdom to request for military aid. However, all the nobles that they approached turned them down due to various reasons, primarily because the Royal Army still hadn't recovered.[14]

The Witch of the Falling Kingdom Arc[]

Main article: The Witch of the Falling Kingdom Arc

When the Sorcerer Kingdom declared war on the Re-Estize Kingdom, it was said that the Royal Army had been mobilized once again for the battle but this time around, led by Prince Zanac. It was comprised of levies from the neighboring nobles, the capital’s militia, conscripted prisoners, and able-bodied men drafted from the refugees that totals over 400,000 men within their ranks. Although not many had suitable equipment prepared for them, there were a lot of people who only had a club to bring with them into battle.

On the plains about half a day’s worth of marching away from the capital, the Kingdom’s army had already established a front upon receiving news that the Sorcerer Kingdom was invading from the west. According to their battle plans, they were to wait for the Sorcerer Kingdom’s army there. The front was built upon a wide bit of road that was locked down for this purpose. If the Sorcerer Kingdom’s army was to continue on their current, straight trajectory, this would be the most effective method. They had been manning this front for two days before being confronted by the Sorcerer Kingdom's army.

Before the battle started, Prince Zanac was given an audience with Ainz Ooal Gown in the last attempt to avoid the battle. Although the Sorcerer King treated the prince with courtesy and the conversation went pleasantly, Prince Zanac still failed to convince him to change his mind. Accepting that their fate was sealed, the prince made a final request to the Sorcerer King; giving him and his own countrymen a gentle death painlessly.

However, after Prince Zanac returned back to his army's side and informed the result to his subordinates, a group of nobles, who were extremely desperate to survive, assassinated the prince and brought his head to Ainz Ooal Gown in the hope that their life would be spared. Disgusted by their sheer cowardice and disloyalty, the Sorcerer King instead send nobles, along with their families to Neuronist Painkill and ordered Albedo to prepare a proper burial for the fallen sovereign.

The assassination of Prince Zanac had erased all hesitations in the Sorcerer King's mind. Thus, he ordered Cocytus and Mare to destroy the Re-Estize Kingdom with the full extent of their abilities. The Royal Army, consisted of 400,000 men, was annihilated in only one hour.[15]


A Kingdom Foot Soldier

The Royal Army was a grand military venture that drew conscripts from all regions including every village of the Re-Estize Kingdom.[16] However, individually the soldiers that composed of the army were weak farmers. Its only advantage was using sheer force of numbers to achieve victory against its foe.

By Jugem's estimation, the majority of the conscripted men in the Kingdom's Army would be at most level 2. Trained soldiers hired and under the service of the nobility would be around level 10.

The skills of a soldier of the Kingdom's Royal Army were only slightly better than that of its ordinary citizens. Even compared to the Baharuth Empire’s enlisted soldiers, they were treated as weak.[17]


  • 50,000 militia soldiers are needed to stand against one legion, which consists of 10,000 trained knights, from the Imperial Army of the Baharuth Empire.
  • The favorite tactic of the Royal Army against the Imperial Army is the spear wall. Not only because the Imperial Army is mostly comprised of cavalry but also because the conscripts have little tactical training for anything more complex then bracing with spears.
  • The older conscripts usually have been jaded and have accepted their fate, the younger ones are more energetic due to desperation, however over time they will become fatalistic like their older companions.
  • Morale is usually at an all-time low for conscripts because the empire always mobilizes during fall which is the harvest season.[18] The conscripts will go back to dilapidated villages and a bleak future awaits them.
