In her first life, she was obsessed with the "Arachnea," a spider-like race in the video game she adored. As an evil-aligned faction, they sought nothing but victory; the more they conquered, the more they grew, using the bodies of their enemies as fuel to multiply and expand the ever-growing swarm.
When she awakens, she is in a body younger than her former one and finds herself surrounded by the Arachnea, who call her "Her Majesty." She soon realizes that she too is connected to the hivemind, and her precious Arachnea still wish for victory—over who and for what ends, that is unclear, but their lust to win is undeniable.
To fulfill their desires, she leads the Arachnea, destroying all who are vile in the world. From the religious zealots who murder those unlike them, to the immoral slavers who deal in the lives of others, none are free from her path of carnage. You can plead, weep, or beg, but she has no mercy—the swarm of the Arachnea lives only for victory and to serve Her Majesty.

Her Majesty's Swarm Manga Vol. 1
Her Majesty's Swarm Manga Vol. 2
Our protagonist is a college student who enjoys playing as the evil-aligned faction Arachnea in her favorite real-time strategy game. One day, she finds herself in a world similar to the one in the game; additionally, her body is now that of a Fourteen-year-old girl. While things are a bit different from how they were in the game, one element has remained the same: she is the leader of the Arachnea. The insects under her control, collectively known as the Swarm, praise her and implore her to lead them to victory. In order to survive, she raises her Swarm and forms friendly relations with the elves of the neighboring forest. But after a slaver traveling through the forest murders one of her Swarm and the nearby kingdom's knights burn down the elven village and massacre its people, she prepares to launch her counterattacks in the name of revenge.
However, revenge is merely a pretense for attacking the countries of this world. Her command is masterful and severe, as one who has played the game in real life...
A girl who was enjoying a certain real-time strategy game suddenly reincarnated in another world. Without knowing who she was or why she was there, what appeared before her was the terrifying giant army of insects, Arachnea. A corps of horror that eats everything pledges allegiance to her.
"If they hit us, we will hit back. I will inherit your will." "Sorry, but I can't accept this." "Yes, I finally found an enemy to defeat."
Tactician Command [RTS Gamer]
Early-game rushes were one viable tactic to achieve victory; lurking behind the faction’s defenses to build up an army big enough to sweep the map was another. Teaching into the most expensive units to crush the enemy with punitive force was yet another win condition. So long as you were able to look past their exterior designs, Arachnea units were relatively balanced and well-rounded. I won countless matches with them, even earning victories in some online tournaments. All my consecutive victories with the Arachnea had earned me a moniker among the other players: “BugSis.” I found it to be a rather cute, charming little nickname and liked it a great deal.
Grevillea is a Extraordinary Genius and can Orchestrates events in a world-wide scale and her thinking capabilities are also empowered by each and every Swarm Member (Numbering over 300 thousand members). Her personality is mostly peaceful, avoiding war if possible. However, due to her connection to the Swarm, she strikes relentlessly to those who do not deserve mercy, slaughtering them, torturing them and putting their bodies up on display. A cruel and ruthless general while fighting, who, although cares for her Swarm that die, will not hesitate to send them to their deaths in order to win.
The 《Arachnea》 consisted of a race of insects—or rather, its units were more similar to spiders—and its political system was totalitarianism. Its ecological structure was that of a colony built around one queen. As for its military, the Arachnea formed troops that devoured their enemies, leaving only bones behind. They invaded the other factions indiscriminately, never once engaging in diplomacy. If I felt like being a bit cynical, I could even go so far as to label it fascist. But it was the one faction I found easiest to play, and I gradually came to adore its many units. When it came to online matches, I would always pick the Arachnea with fixed devotion.
Arachnids were part of the Swarm, collective troops of the Evil-Arachnea. The brilliant luster of their black, elegantly curved exoskeletons... Sharp, vicious fangs which struck the fear of death into all who witnessed them... Scythe like appendages that could slice through anyone and anything... Lethal and effective venomous stingers gracing their carapaces... This was the very same Swarm I had spent countless hours nurturing with only the computer monitor separating us. The ones standing in front of me had long, sharp scythes that were disproportionate to their bodies and long, narrow legs. These characteristics belonged to the Ripper Swarms, an easy-to-mass-produce type of Swarm used for early-game rushes. I had used legions of this type of Swarm to smother enemy factions dozens upon dozens of times. No unit could be more nostalgic for me. They even helped secure my win in some tournaments.
The Arachnea, on the other end, lived on meat. It typically gathered meat from hunting grounds, which were generated as part of the map, in order to increase its unit production. Only Worker Swarms could be produced from gatherable plants, with all other units requiring meat to produce.
All Normal unit Swarm have Predation ability to able to produced and survived.
Due to this ability, the Swarm do not feel pain nor death.
The Swarm are resistant to diseases and poison due to their race, as their race handles poison quote well. The only exception is the Queen.
The Swarm does not sleep, having basically endless stamina. The only exception is the Queen.
Hive mind: The Countless Swarms even though they are all different individuals, They all talk the same way, because they form a collective consciousness centered around the queen. The swarm sync their minds and share with the queen.
Due to all of them being a part of a Hive Mind, including the "dead" members, the experience and knowledge of each and every Swarm is also acquired by all the members of it, allowing to adapt to attacks, act immediately and with perfect cooperation. Due to this, all kinds of information is shared through the collective consciousness, including information from all the senses, experiences and thoughts. The Swarm have absolute faith in their Queen and follow her orders even if it means to die. If one connects to the Give Mind, they are being swallowed up and made part of it.
Ripper SwarmsIf I looked beyond the Ripper Swarms (Arachnea’s Anti-army units). They were grotesque but had a beauty of their own, reminiscent of what you might see in a high-quality horror film.
Grevillea doesn't fight herself; she commands the Swarm which grows by devouring others, eating their meat and rapidly reproducing in special constructs called "Flesh Furnaces". Each Swarm member is connected to the others via the Hive Mind and follow Grevillea's command perfectly. All Swarm except the Arachnea Queen have potent poison.
the Genocide Swarm upgraded version of the Ripper Swarm:. As its name implied, this type of Swarm was meant for slaughtering the enemy in large numbers, no matter what that enemy might be. A large Swarms with dense, weighty exoskeletons. They had curled fangs like a centipede, and their limbs ended in scythe-like blades that stabbed into the ground. Essentially, these units were the Swarm equivalent of heavy tanks.
I could see some Worker Swarms (Arachnea’s Builder Unit). They were the worker units that built new structures, repaired existing ones, and produced siege weapons. I often found myself enchanted with the insectile architecture and design of their constructions.
Worker Swarm that do not fight, but instead gather resources and are able to construct various buildings which aid the reproduction and evolution of the Swarm.
Digger SwarmsThere were also some Digger Swarms (Arachnea’s Anti-army units) next to them. Their production cost was higher than that of the Ripper Swarms, but in exchange, they were capable of a unique action—burrowing underground and digging their way into the enemy’s base. They were meant for surprise attacks and were fairly difficult to use. Once mastered, however, Digger Swarms would prove to be dependable units capable of felling entire strongholds without the aid of any siege.
The basic infantry of the Arachnea Race. Ripper Swarms are mobile bugs as tall as a human which look like a mix of a spider and a scorpion. They have huge fangs (their fangs are as big as the arm of a human) which tears apart through steel armor with easy. Especially resistant to piercing attacks.
Basically Ripper Swarms that can burrow underground. They can be summoned right under the opponent, drag them underground and drown them under the earth or catch the enemy off guard and grab their legs, immobilizing them. They are powerful enough to immobilize an Angel.
Parasite SwarmThe Parasite Swarm (Arachnea’s Scout units) latched onto its victims, turning them into puppets that obeyed any orders its master—or mistress, in my case—gave. If I were to order him to commit suicide, this man would take any measures possible to kill himself. They were like zombies. Eventually they would be able to walk normally, but since the Parasite Swarms had only just been planted, they weren’t yet functioning effectively. I’d need to keep that in mind the next time I used them. If our enemies could tell what had happened to victims of the Parasite Swarms, the unit would go to waste.
Small Swarms that look like a spider. Palm sized, they are forced into the enemy, taking over their body and stay in the target's throat, having tentacles reach the brain. The victim still has their perception, but no control over their body whatsoever.
Toxic SwarmsOne of the Arachnea’s long-range units. Once we had gathered enough souls, I had finally been able to unlock them. The Toxic Swarms were capable of something the Ripper Swarms, Digger Swarms, Parasite Swarms, and Masquerade Swarms were not: attacking from a distance. The Toxic Swarms obediently swung their large tails and fired what looked like arrows from the tips. Those arrows pierced into the downed the opponent. Legend has it that the poison in their tails is capable of downing a dragon. Not sure if that’s true, but it’s still a pretty powerful toxin. I doubt anything that takes the brunt of it would get away unscathed.
Fire SwarmsFire Swarms Arachnea’s Long-Range Units. A Fire Swarm possessed two abilities. First, it could spew a high-temperature gas at the enemy. The attack was powerful, but its damage per second was low. If an Arachnea player wasn’t careful, her Fire Swarms might be killed before they could defeat the enemy. Secondly, this Swarm could self-destruct. It shared this ability with the Masquerade Swarm but far exceeded it in sheer firepower. One burst could easily destroy an enemy’s defensive fortifications.
Flap SwarmsThe Flap Swarms a Arachnea’s Airborne Units (Dragon like Swarm) produced by Aerial Flesh Nest, it would likely be no match for the wyverns. Nevertheless, having this unit able to been an eyes in the sky would be a major advantage in battle.
Dreadnought SwarmDreadnought Swarm a Arachnea’s Heavy units. The Dreadnought Swarm was basically a ground-based battleship. It looked like a rhinoceros beetle with countless, centipede-like legs. It was four times the lindwyrm’s size, and it moved thirty times slower from a Genocide Swarm.
Bone TrebuchetsBone Trebuchets a Arachnea’s Heavy-Siege units, a Siege weapons required gold to unlock, so I could only make the most basic ones. A Bone Trebuchet was, as its name implied, a contraption that launched the bones of the dead. It was capable of firing long distances but dealt little damage. However, it would be more than enough to harass the enemy.
Carrion CannonThe Carrion Cannon launched decayed flesh. It poisoned any units within the impact zone, and caused nearby structures and facilities to decay. Although its firepower was low, those secondary effects were nasty. It was one of my favorite weapons. As for the design, it looked rather like an insect and was adorned with decaying flesh. Like most Arachnea constructions, the thing was pretty grotesque. It is a the upgraded version of Bone Trebuchets.
The most basic Swarm Siege weapon, they fire rotten flesh to the enemy, causing damage to both living and non living things alike. The living units are also poisoned and contract diseases, which result in their death in a short amount of time.
Chemical SwarmsChemical Swarms (Arachnea’s Long-Range Units). These Swarms inflicted greater poison damage than any other unit, and they were even capable of healing their allies. They were a complete upgrade of the Toxic Swarms.
LindwyrmThe Lindwyrm was a relatively tricky opponent for a standard unit. Lindwyrm performed like heavy tanks, and their high defenses meant normal attacks wouldn't dispatch them easily. They could also function like battering... They didn't require riders, as they were accompanied on the battlefield by commanders who could issue them orders. They were among the toughest, most durable standard units in the game; even the Carrion Cannons' continual
poison and the Fire Swarms' explosions might not be enough to stop them.
Knight SwarmSérignanThe creature that emerged was another type of Swarm, only this one had the upper half of a human and the lower half of an insectile Swarm. It had ruby-red eyes and white, braided hair that spilled over its back. The Knight Swarm’s upper half was covered in white armor, and it had a longsword sheathed at its waist. It gave the immediate impression of a knight. This was the Knight Swarm Sérignan, a different unit from the Ripper Swarms. It was something called a hero unit. By gaining experience points, it was capable of becoming even more powerful, eventually growing into a one-man army that could topple the game’s balance. That said, each faction could produce one hero unit, and only once; as such, the chosen unit had to be carefully raised and protected. Upping its experience points without it dying was a more formidable task than it seemed at first glance.
Like all of the factions’ hero units, the Knight Swarm Sérignan had its own backstory. This unit’s backstory was that it was a knight who had been exiled for defending a pagan child, eventually coming under the protection of the Arachnea’s queen. Like all of the factions’ hero units, the Knight Swarm Sérignan had its own backstory. This unit’s backstory was that it was a knight who had been exiled for defending a pagan child, eventually coming under the protection of the Arachnea’s queen. The Knight Swarm Sérignan standing before me had a certain androgynous beauty but a distinctly feminine face, and I could see that she had breasts under her armor.
Skill: 《Mimesis skill》: A skill certain available only in Arachnea Hero unit, Skill can change into Human form to hide the Arachnea Race. 《Holy Sword of Destruction》: A sacred treasure befitting of a fallen holy knight a demon blade that can cut through light. 《Evolution》:The Knight Swarm’s evolved form is called the Bloody Knight Swarm. Imagine yourself clad in red armor; that’ll be your new form.” The Knight Swarm’s evolved form is called the Bloody Knight Swarm. Imagine yourself clad in red armor; that’ll be your new form.” When she became the Bloody Knight Swarm Sérignan, she would not only have new coloration and an additional pair of legs, but she’d also receive a huge stat boost. As an intermediate unit, she would defeat most enemies with one blow. To begin with, Sérignan was considered a strong hero unit that required slightly less experience points to level up than other hero units, and she had slightly higher stats. This was balanced out by the fact that toward the endgame, she needed more experience points to advance and her stats didn’t increase quite as much. Still, once she reached her final form, she reigned over all as one of the highest ranked units in the game. In fact, Sérignan was one major reason why the Arachnea had so much potential as a faction. Raising Sérignan properly meant eventually getting a unit capable of breaking the game’s balance.
Masquerade SwarmMasquerade Swarm (Arachnea’s Scout units), In terms of fighting power, a Masquerade Swarm was the same as a Ripper Swarm, but it had double the creation cost. In exchange, however, it had a very important ability. At my order, the man’s face split in half, revealing two massive fangs. Insectile legs extended out from his back, and his—or rather, its legs turned into a pair of venomous stingers. With its transformation complete, it stood before us in the unmistakable form of a Swarm. . It’s a special unit capable of sneaking into enemy territory disguised as another faction’s worker unit and causing disruption and chaos from the inside. The Masquerade Swarm’s special ability was Mimesis. but the only generic units capable of using Mimesis were Masquerade Swarms.
A Swarm used mainly for infiltration, hence having low stats (but still enough to be as strong as a human knight). Has a special ability called Mimesis (which Lysa and Sérignan can also use) to turn into a human. Even with appraisal, their race cannot be found out and their special ability is blending in the humans and then self destructing to cause discord. As their explosions can be seen from all around the city, they should be at least Building Level.
Skill: 《Mimesis skill》: A skill certain available only in Arachnea Hero unit but Masquerade Swarm is a special unit able to use the skill. Skill can change into Human form to hide the Arachnea Race.
Power PlantThe power plant was the standard power energy source production facility used by Swarms. The power plant produces 100 power units. This amount is less than sufficient to run a large base, meaning that the more buildings a base has, the more power plants it requires to maintain full functionality. Power output is directly related to the power plant's condition, so they must be protected from enemy fire. Low Power decreases production efficiency by 50% so keep them maintained.
Fertilization FurnaceIt still had a working power plant, a Fertilization Furnace, and a flesh depository. I had even built some of our newly unlocked structures and facilities here, but I didn’t plan to use them until later down the line. At the moment, we didn’t have enough resources for them to start producing units.
Research unlocked new units and structures. Research required gold and souls, though different types of research required different amounts and varieties of resources. Developing new units required souls, while new structures required gold. Some factions were exceptions, though; those who used golems needed gold to unlock those units, and ghost-type factions used souls to unlock their structures.
These structures have functioned on something similar to the game’s mechanics, and we could utilize teleportation magic able to move a large swarm or meat to the base.
Flesh Depositories [Meat ball] where they would be used to produce more Swarms units (Worker, Digger Swarm, etc.)
Massive Fertilization Furnaces Upgrade version of normal Fertilization Furnace it double the size of it and it faster the production making for the swarms.
Converter FurnaceConverter Furnace ” I said, walking over to a nearby structure. “It turns other living beings into Swarms. I built it thinking we could capture wild animals like bears or wolves, or even monsters, and forcibly turn them into Swarms. This was one of the new structures I’d asked the Worker Swarms to build. Its primary function was transforming non-Arachnea units into Swarms. If I were to use it on bears, for instance, they would become Swarms that had bear-like traits; if I used it on wolves, I would end up with Swarms that had an especially keen sense of smell. The transformed units would also be loyal to me, since becoming a Swarm linked them to the collective consciousness.
