Chapter 2: Battle For Planeptune

Dimension: Hyperdimension

Date: 13 Years and 2 Months ACW (After Console War)

Station Area. It was nothing special for Planeptunians as it was just another part of the city where most people or adventurers hang out in any shops or restaurants. It's also where the Planeptune's main railway station is located, which serves to connect to other railway stations from the cities of Planeptune. There are rumors that the Gamindustri Friendship Council plans to build a railway that could connect all the GU member nations, with CPU Purple Heart possibly advocated the idea first.

The area was once a breeding nest for monsters until it was eliminated by the CPU Purple Heart and CPU Purple Sister. It is also where the current CPU of Planeptune was teleported to Ultradimension after Rei Ryghts; the founder and the leader of the Citizen's group, deliberately sent her away.

However, it became a tourist site when it once became a battleground between Rei, who acquired a CPU power through a fairy named Croire, and CPU Purple Heart and CPU Iris Heart from Ultradimension Planeptune. It became more prominent as the location of the starting point of relations between Hyperdimension and Ultradimension and later, the formation of the Gamindustri Union. With people celebrating the Union's foundation today, it became a hotspot for Planeptunians and tourists; both from member states and foreigners outside of their dimensions. As such, this would have been a joyful event for all.

But today would be an unfortunate one.

In the streets of Station Area of Planeptune, a blue short-haired teenager named Lily, wearing a Primm Armor, gunned down several enemy medieval soldiers trying to charge her with her Primm Rifle. As she was reloading, she spotted two enemy mages conjuring a fireball simultaneously before throwing them at her. She jumped high to the air, avoiding the magical attack and repaying that by shooting the two mages down.

Landing back to the streets, Lily looked around her surroundings and saw no other enemies around her, besides the gruesome bodies of medieval soldiers.

"That's all of them I suppose."

Just then, Lily heard running steps behind her and looks back to check if they are invaders. She was relieved when she saw a group of Gamindustrian Guild members running towards her. In front of them, she also saw the legendary lone adventurer; Falcom, who she is a big fan of. Even though the adventurer has grown up somewhat, everyone and her close friends still saw her as the same adventurer as before.

The group stopped near her as Falcon asked in concern. "Are you alright?"

Lily nodded. "Of course. I have already taken care of this thugs trying to attack me."

"Glad to hear it." Falcom smiled in relief. Then, she turned serious. "So, what's the situation here citizen?"

"Somewhat stable for now." Lily answered. "My people and the Guild members are still holding the line against these bastards. If it wasn't for the group that warned about the attack, they would've killed more by now."

"Yeah… any casualties?"

"Unfortunately, the group and my people nearby that first encountered these invaders were killed at the first wave, though not without taking more of these invaders with them. Those that survived had to retreat to higher ground and hold the line with others until our armies arrived."

"Damn it! I wish they weren't."

Even though Dark Purple Crisis was over for 3 years, Falcom still hasn't moved on from that battle. Seeing those Allied Gamindustri and the Guild forces, especially young ones, dying in the fields of the Dark Castle still haunts in her dreams. Although it was lessened after getting a therapist, it still remained in her mind.

"I have the same thought." Lily said. "But they did buy us time to warn the others about the invaders Lady Falcom, and I'm going to honor that by pushing them back with my fellow Planeptunians."

"Then don't fight alone. Me and the Guild members here are with you citizen to provide support." Falcom offered.

Lily nodded, thankful for the assistance. "Thank you. Please follow me, I saw somebody currently holding the invaders at the edge of Station City." She immediately went straightforward while Falcom, and the Gamindustrian Guild members followed suit.

Once they reached the site, the team found that a group of armed Planeptunians, Loweeians, and Leanboxers fought together to hold the invaders advancement further. Not only them, they saw several foreigners fighting alongside them, with one using a fire magic to burn 3 invaders at an instant and another charging towards an invader and killing them with a beam katana before retreating back to his group. Falcom was shocked of the bodies of the invaders the defenders killed laying in the streets.

Thankfully for Falcom's group, neither side noticed their presence as they are in a top of the bridge, hiding behind. She then gets an idea. "New plan. We're going to surprise them by flanking the invaders from the rear before they had the chance to attack us."

"Great idea, Lady Falcom." a Guild member responded.

"On your orders ma'am."

"Alright. The ranger team would stay here and provide cover while me and the melee team would charge at the invaders." Falcom raises her hand. "On my signal."

"3."

"2."

"1…" Falcom then lowers her hand. "… Go!"

Along with a few Guild members, Falcom charged straight at the closest enemy she could find and strike him down with her Dragon Slayer. The invaders were completely taken by surprise. Before they could retaliate, two Guild members quickly rush towards the invaders and slayed several of them with their Primm Swords. The invader's mages tried to retaliate as well, but they were quickly shot down by the ranger team back at the top of the bridge.

As Falcom kills another one of the invaders, she noticed one of them in a horseback, shouting to his men on what seems to be an order. As expected, the invaders charged at them. At the same time, the invader's archers unleashed a volley of arrows flying towards them. Just before Falcom and the rest of her melee team got hit, few individuals quickly step in front of them and summoned a dome shield, blocking the archers arrows on time.

"Are you okay?!"

"Wait! You are…?!"

Falcom gave a quick look and saw the individuals that saved them were the Planeptunian Bravers; people who used both Katanas and Bows. "Yeah, it's me Falcom. We here to back up all up, so don't worry about us."

"Hell yeah!"

"Then let us show these invaders what they're messing with!"

The four Bravers charged towards the invader's archers with rapid speed. Before the archers could act however, they were immediately slashed to pieces, along with the invader's soldiers with them. Some of them tried to attack them, but the Bravers used their Mighty Guards to block before counterattacking by slicing them apart. They won't be alone though as their group and their reinforcements joined the fight.

Two Planeptunians Fighters; one equipped with a twin daggers and another one with a knuckles, charged to an unguarded invader group. The Planeptunian jumped to the air before rapidly descending down to punch the street below him, causing a shock-wave that sends the invaders to the air. His partner also jumped, but goes straight to the invaders that is still in the air and sliced them up in quick succession before their pieces landed onto the ground.

Despite the seriousness of this situation, Lastationers didn't want to be trumped by their oldest rival. So the three of them charged into the fray as well and fire their rifles upon the invader soldiers and mages alike. When one invader soldier tried to run towards the armed group while calling them 'devils', one of the Lastationers sling her rifle onto her back and pulled out a Claw machete from her belt. Dodging his attack, she then used it to decapitate the invader's head by the neck before kicking the now-dead body onto the ground.

Loweeians magicians used fire and thunder spells to burn and electric the invaders, sometimes to ashes. Lastationers and Leanboxers fired their ranged weapons from a safe distance, mowing a lot of the invaders by the hundred's. When either the surviving invader archers and mages tried to attack them, Leanboxers throws a device on the ground, summoning an orange particle wall to shield their allies from harm. Once the wall was dispersed, they resumed firing upon the invaders.

In the Imperial side, they were horrified from what they had seen. They initially thought this would be like the past campaigns from their world, defeating their foes with their numerical superiority. Yet, they saw their fellow Imperials were slaughtered in front of them. This was much like the fighting Warrior Bunnies in a War that they participated years earlier, but not to this extent.

One such Imperial general on a horseback recognized this. He knew that without reinforcements from the Gate, they would die here. However, retreating from the battlefield would result being dishonored from the Imperial military and striped of his noble title. As such, he would not do so and he rather die than be enslaved.

"Do not let their tricks stop us! Push forward men, for the glory of the…." Before the Imperial general could finish his sentence, his head was blown, with the blood spilling onto his horrified escorts.

In the same rooftop as the Leanboxers, a Loweeian sniper, equipped with a Lowee LAF sniper rifle, raised his fist as he got a head-shot on what he saw was a possible leader of this invader force. "Nice shot man!" Another Loweeian remarked.

"Thanks!"

"Hey! Looks like they going to run!"

As one Leanboxer said, the defenders saw the invaders immediately run away from them in fear, confirming that rider the Loweeian sniper shot was their leader. Some were disturbed when they saw the invaders didn't even help their kin and stepping on them as they retreated. Nevertheless, they saw the invaders retreating as a victory and many of the defenders cheered at the fact.

For Falcom and the Gamindustri Guild members, they sighed in relief. "Thank the True Goddess." Falcom said.

Just then, she and her group heard a vehicle sound behind them. Turning around, they saw a convoy of Planeptune's Crusader tanks and N-Forcers driving towards their location, accompanied by Planeptune's soldiers marching near the vehicles. The arrival of Planeptune's army only cheered the defenders more. They shortly stop near the building where the defenders hold up.

The leading Crusader tank, a hatch was opened on top of it and a head pops up, revealing an older man with a mustache wearing an black officer cap with the symbol of the Planeptune nation. When he exited the tank, he was wearing a white and purple Planeptune officer uniform. He then walks towards Falcom before stopping. "Are you the lone adventurer Falcom?"

"Yes."

The Planeptune officer offers a handshake, which Falcom accepts. "Lieutenant General Felix of the Planeptune's Army. Thank you for holding the line against the invaders. Should've expected from a legendary adventurer such as yourself."

Falcom pulls her hand back as she gave a smile. "Thanks. But the defenders are the ones who hold the line here first. Me and the Gamindustri Guild members just aided them."

"Then I'll give my thanks to them as well." Lt. General Felix replied.

Pulling her hand back, Falcom spoke. "So are you here for the invaders?"

Lt. General Felix firmly nodded. "Correct. We have already received reports from one of the Guild member that first encountered the invasion force in Station Area. As such, we were ordered by Govenor Arfoire to push them back from the portal they have come from."

"Does Neptu… I mean, the Planeptune's CPU is aware of this?"

Lt. General Felix shook his head. "No, but we have sent a message to the GU Alliance Headquarters on Neptunia City about our current situation. The message probably must've reached to either Histoire or Lady Purple Heart by now as we speak."

"Do you need our assistance then Lt. General?" Falcom offered.

But the old man shook his head. "No need. You and the group here continue maintaining the line until we have taken care of this invaders that invaded our nation. Luckily for us, more of our forces are beginning to encircle the position of the invader's base and would soon push our forces against them."


On the balcony of Silver Tower Ark, the party goers continue to enjoy the festivities when all the sudden, a Planeptune soldier barges in on event. His unannounced entry, cause the music to stop and and all the people present stare at him. The soldier inhales and exhales for a while before hastily bowing to the CPUs. "Lady Purple Heart, Lady Histoire, and Lady Nepgear, Planeptune has been attacked!"

Histoire and the CPUs were taken aback at this news, including Purple Heart. The people around them were shocked as they remembered the city hasn't been attacked since the Dark Purple Crisis. "What?!" Nepgear shouted.

"Who the hell's attacking the city?!" White Heart shouted.

"We don't know." The soldier admitted. "One of the Gamindustri Guild members managed to report to us about an invading army coming from a structure-like portal. Currently, the group that sent one of theirs to contact us are currently holding their ground, but there is no reports coming from them."

There was silence from the CPUs.

"What about my army?" Purple Heart immediately asked. "Are they aware of this?"

"Yes, Lady Purple Heart. They told us they are starting to contain the enemy force around Station Area and currently engaging the enemy force. Prior to our forces arrival, the Gamindustri Guild, our off-duty soldiers, GU citizens, even some tourists were involved holding their key positions to prevent them spreading any further."

"During all of that however, reports claimed that the enemy were pressing hard from the defender's positions and already have 100 casualties from their side. Several buildings and vehicles have been either damaged or burned by the enemy's flying creatures and their monsters." The soldier finished.

Purple Heart clenched her hands tighter. Her Planeptune have been attacked many times than the other nations and its just been recovered from its wounds 3 years earlier. Behind her, Nepgear also felt the same way 10 years ago when ASIC took over Planeptune briefly after being tricked flying to Leanbox by Underling.

Before Purple Heart can reply, Green Heart barge in on the conversation. "What do you know about these invaders?"

"Well…" The Planeptune soldier looks at Purple Heart, who gave him a nod of affirmation. "… not much. One of the messengers from that group says that the enemy were wearing old fashioned armor like in the Ancient Era, including their battle tactics."

"Are you saying that our enemy is invading Planeptune is a medieval army from another dimension?" Noire questioned.

"We still trying to get information on the ground, but yes. That's what they said." The soldier replied. "Several reports coming from the Gamindustri Guild members that the beast creatures are exotic and sentient beings, much like our allies. One of our soldiers managed to capture one of them and it can speak, albeit in the different language. They are currently in our custody."

"What is the status of Station Area right now?" Purple Heart interjected.

"Currently occupied by the invading force at the start. However, due to their military equipment being outdated, aside from their war creatures, our generals believed they should end the battle by pushing their army towards their invader's base and capture their makeshift portal. However, they need your permission before they can do so." The Planeptune soldier explained.

After some thought, Purple Heart gave a firm expression to the soldier. "Alright. Tell my generals that they have my permission to stop the invaders once we will arrived on Planeptune to assist them."

"Of course Lady Purple Heart!"

The Planeptune soldier saluted his goddess before heading off. Turning to her CPU sisters, Purple Heart spoke. "Sisters, do you wish to go to me? This wouldn't take long to finish."

"Isn't it obvious? Of course we'll go with you Neptune!" Black Heart replied.

"Planeptune is part of the Union and we would be a disgrace to our mother if we never help our sister's nation in dire need." Green Heart added.

"Whoever they are, we're going to beat the hell of them as always!" White Heart shouted.

"Then let's transform back to our forms before we go."

The three nodded at her as their whole bodies were covered in light. When it faded, their current clothing were gone and their appearance now changed into their CPU battle forms. Neptune looks at her sisters and were shown to be battle-ready, including herself. "Alright, now we can go…."

"We're coming too!"

They heard a few sounds of moving chairs. Looking behind them, the CPUs saw their lovers now standing with firm expression. "We don't want you to go alone, so we're going with you. Its our city after all." Luis declared.

"Yeah! We can't just sit here and let those bastards do as they please!" Andrei exclaimed.

"Calm down." Hiroshi said. "Rushing like you did during the Crisis would bring us nothing but headaches."

"But he's right, we can't just sit here." Hyun-ki pointed out. "Besides, I'm curious about those invaders from another world and how they managed to

"Can we talk about that for later? Right now, we need to save Planeptune."

"You guys…." Purple Heart gave a small smile, thankful for the boys, especially for her beloved.

"Alright." Black Heart relented. "Just transform to your CPU Brave forms already and let's go."

The four boys nodded and, like the girls, their whole bodies were covered in light. When it dispersed though, their formal clothes they wore not too long ago were gone and they have now the appearance of a CPU. Unlike the CPU girls, their suits are identical to each other. The only difference were the colors; Luis's suit were purple, Hiroshi's were black, Andrei's were white, and Hyun-ki's were green. Their hairs also changed color as well. Their suits were similar to motorcycle suits, but more futuristic-style and has a fluorescent-like glowing strips illuminating them; Luis's were blue, Hiroshi's were gray, Andrei's were sky-blue, and Hyun-ki's were white. Each have a futuristic-style of shoulder plates attached to their shoulders. They also wore gauntlets and boots. Lastly, their wings are similar Purple Heart's Lost Purple wings, but theirs were shaped like angel wings and its energy colors were the same as their suits.

"Alright, we're ready!" Luis nodded.

"Then let's leave immediately." Green Heart replied.

"We're coming with you too!" Nepgear spoke out. Just as the CPU candidates and the rest of the CPUs prepare to transform into their forms, Purple Heart raised her hand to stop them. "Neptune?"

"There's no need for all of you to come."

"But…!"

"If that soldier spoke the truth, we really just fighting a medieval army from another dimension." Purple Heart stated. "Even though my army and my citizens would be enough to take them down, we will go to aid our people regardless."

"Besides Histoire, who would function our government without us?" Black Heart asked. "No, you all stay here and continue governing in our place."

"I agree with Noire." Histoire said as she floated between the Hyperdimension CPUs and their Candidates with her book. "Without the rest of the Oracles, the CPUs candidates would remain here in the Ark to continue ruling in their place for now."

"I hate to say it but Histoire is right." Gray Heart crossed her arms. "Its better you four stay here and rule in your sister's place till they came back."

The Lowee CPU candidates; Ram and Rom, who both are now teenagers when they requested their mother to turn them into one after Kurome's defeat. Both were still in their form as CPU White Sisters (now in teenage form as well) and were wearing their white & light-yellow dress with Ram's light blue & Rom's pink ribbons tying in their waist. "But we want to go with our big sister!" White Sister (Ram) angrily replied.

"Yes, I want to go too as well." White Sister (Rom) quietly said.

Blanc's counterpart though, slowly walks behind the twins and pat their heads. "You heard your sister, you two are staying here to maintain her seat at the Council till she gets back."

"Yeah! Ploot and others would be fine!" Yellow Heart chimed in.

Ultradimension Vert walks besides Nepgear. "You shouldn't worry about your sister Nepgear. If what the soldier says is true, then it would be easy for them to handle this one."

Nepgear sighed in resignation, knowing Ultradimension Vert and the others were right. "Alright. But please be careful Neptune!"

"Of course Nepgear." Neptune gave a smile. She quickly turns her head to her Oracle. "Histoire, I want you to announce our representatives within our nations about Planeptune's situation with the Council and send whatever help they can provide."

"I understand. Should I also inform Lady Arcadia about this?" Histoire asked.

"Please do Histoire."

"I also be coming with you my little cuties." Iris Heart spoke out, already in her battle form. "I will make sure those interlopers would suffer my punishment for attacking my favorite sister's city~."

Many of them sweat-drop at Iris Heart's declaration, but nonetheless didn't oppose of her going with her Neptune's group. In fact, they almost feel sorry for the foreign invaders. Almost.

After the rest of the CPUs gives their own words of 'be careful' and 'good luck' to them, Purple Heart then looks at her group. "Let's fly to Planeptune everyone."


Legate Decimus slammed his hand on the table inside of their command tent, angry that this invasion did not go in the way he planned. He and the other Legates initially anticipated that this would be much like the last conquests from their world. After taking care of what he seems to be a small group of city guards and mages, despite the loss of over 800 of their men, victory was assured in his mind.

That is until half an hour later, Decimus was getting multiple reports from their generals that their advance is stalled by the town guards and powerful mages. He already sent the Roen and Missna clans soldiers as reinforcements to reinforce the 10th Legion and their auxiliaries in the Northwest, directly to the large tower where he also believes to be the enemy's capital. Legate of the 7th Legion also sends his half of his legion to join with the 5th Legion in the east to capture the enemy's harbor for their future invasion. This left half of the 7th Legion and few auxiliaries to guard their main encampment.

However, one of their messengers from reports that any reinforcements he sent were killed while marching towards their forces. Those that did make it, reported that they were being stalled by the enemy defenders and even pushed their forces back. Even the Imperial Wyverns Corps he sent to the skies to recon the entire city completely disappeared and he haven't heard from any of them since.

As more reports coming in from the messengers, Decimus became more and more uncertain that they would taking over this city, much less this world. However, he refused to retreat back to the Gate; both out of pride and potential punishment by the Emperor. Moreover, he refuses to admit that some natives can defeat the mighty Imperial Army. Thus, he resolves to end this siege before that could happen.

The only one who oppose to continue the campaign was Count Colt, who senses they were (rightfully) losing and believes that his fellow counts were dead.

"Legate Decimus, I'm afraid we're losing our men rapidly. We should pull back our men and retreat!"

"Retreat? Are you mad Count?!" The Legate of the 5th Legion yelled. "If we retreated back, we would've seen as weak by our fellow Imperials!"

"Not to mention we would bring shame to our families back home!"

"Can't you all see we're going to lose more of our men if we stay here, we have to-."

Before Colt can finish his words, Decimus pulled out his sword and point it at his throat. "Enough! Count Colt, let me remind you that you have no authority to order us around. Continue to defy us and your trading town will be burnt down, along with your daughter."

The mentioning of his daughter cause the Count to stop speaking, though he grinds his teeth in anger. "Yes… Legate Decimus."

Pleased at his answer, the Legate sheathed his sword. "Very well. I'll let your insubordination be… for now. Today, we will not let the natives oppose us any longer and soon, this city will be the new province of the Sadera Empire!"


"Hold your ground! Don't let these guys break though!"

In another part on Station Area, Planeptune citizens and Gamindustri Guild members were fending the invaders in the streets with their weapons as the enemy repeatably charging to their makeshift barricades, despite the body count. Obviously, the invaders were trying to get to Neptower on the horizon and both groups didn't let them. With the arrival of the Planeptune's Army to enforce them, their victory was all but reached.

The only reason they didn't pushed further because one of their soldiers were ordered to stand their ground till the CPUs arrived here to see the situation personally and assist them.

"Keep firing! We have to hold them back till our goddesses are here!"

"I can't believe this! We throwing multiple spells at them and they still keep coming!" A male Loweeian magician exclaimed.

As they continue to fire and throw spells at the invading force, ignoring the sheer fallen dead bodies, a giant ogre wearing a dark iron armor is charging towards them with a stone mace. An Ion-class Titan, operated by a Leanboxer, step out from the barricades to face the ogre head on. Once both combatants are near, the ogre attacked first by trying to slam his mace to the mecha's head. The titan effortlessly dodged it and instead hit the concrete street. The titan then countered by punching the monster into the head four times before finishing it by blasting its face with a single-shot of its Splitter Rifle.

The body of the headless ogre dropped down into the street and crushing the unlucky Imperials near it. They were shocked at the loss of one of their ogre, but before they can act, the steel golem fire its strange magic starve that sends multiple light balls into their direction, causing more of their brother-in-arms to their deaths and losing more of their morale even more.

Some wanted to flee back to the Gate, but the Imperial general leading the invasion deny their request and angrily orders 3 more giant ogres to destroy the steel golem and its defenders.

"Crap! Hey girl, I need your support here!"

A Legion-class Titan, also operated by a Leanboxer, stopped firing at the invaders and looks at the 3 charging ogres heading to their direction. "Alright, stand back! I got this!" She yelled from the titan as her Predator Cannon begun to rotate.

Before the woman could fire her weapon, she witnessed the 3 ogres had their bodies horizontally slashed to pieces all of the sudden. Then, she found out the cause of their demise; the Planeptune CPU; Purple Heart and Lastation CPU; Black Heart floating in the air, with their weapons covered in blood. Seeing the CPU goddess, made the defenders cheer. Even the two Titan operators joined with them as well by raising their weapons to the air.

Once the cheering died down, the two CPUs slowly descended down to the concrete ground. Then, they turned to the invaders and pointed their weapons at them. Purple Heart declared. "I won't let you harm my people anymore. We are giving you a chance to surrender."

"If you don't, you will all perish here!" Black Heart finished.

There was silence in the invader's side and most of them are looking at each other in confusion. However, one of them in a horseback shouted at his men and they immediately started to charge towards the two with their swords raised.

"Your choice! Noire, lets go!"

"Right behind you!"


In a secluded part of Station Area, two women; a Lastationer holding a near-empty Militech M-76e Omaha pistol on her hands and a near-exhausted Lowee magician carrying a staff were each other's backs as they were surrounded by the light-armored invaders. Prior to their situation, the two of them ambushed an invader group that was heading to the Neptower in another way and killing 84 of them.

They would've finished them off if the Lastationer's D5 Copperhead didn't run out of ammo and the Loweeian almost emptied her mana due to her being an apprentice-level magician.

As the 12 remaining invader soldiers slowly walks to them with their own 4 surviving mages following behind them, the two woman noticed their enemy's expressions were filled with hunger and desire and all of them were looking at their direction. It didn't take long for them to put two on two together and both mentally decided they would rather die than subject whatever they are planning with them.

Before the Lastationer and Loweeian make their final stand, they heard a male voice somewhere. "So picking against two girls are your style medieval fuckers?!"

"What?! Who's ther…?!"

Before the one invader could finish his sentence, his head was suddenly was cut in half. Not only him, but 5 other invaders that were in front of the Lastationer lost their heads as well. When she saw who done it, it was none other than the husband of Lowee CPU; White Brave and holding his signature twin daggers. As she was about to say something, he shouted. "Hurry, take down those soldiers you two!"

Both women nodded and, without hesitation, Lastationer shoot the 3 invaders with her remaining ammo while the Loweeian summoned a fire spell that burned the other three.

"Damn that boy!"

"Hurry, kill the three…. ARGH!"

The other 3 invader mages quickly looked left at the sound of the scream and, to their horror, one of the theirs was currently impaled by blade. Looking behind the impaled mage was a young man, wearing a strange black armor and its has wings, which they instantly concluded it was made in magic, on his back same as that the person who murdered some of the Imperials not long after. He was also holding some kind of swords with a long, curved blade.

Then, they saw the individual pulled the weapon out of the mage's body and it fell down to the ground, now clearly dead. Seeing their fellow mage dead made them angry, especially he had been their classmates since their enrollment at Rondel's magic academy. "How dare you!" The Imperial mage yelled.

Just as they raise their staff to summon a spell, Black Brave quickly rushes to the enemy mages with his dual katanas and proceeds cutting them in half with his weapons, one-by-one in lightning speed. Black Brave take a quick look at the now-dead mages he killed and gave a frown. But then, he shrugged and walks towards the girls, with White Brave joining him. "You girls okay?" he asked.

"Those bastards didn't hurt you do they?" White Brave angrily added.

Both women shook their heads. "No, but they were about to if you two didn't interfere. Thank you CPU Black Brave, for saving us." The Lastationer woman immediately puts her clenched hand to her chest as she says.

"You too as well, CPU White Brave…" The Loweeian woman bowed in gratitude.

The two CPU Braves nodded in response. "Okay, you girls should probably find some shelter and rest. Planeptune's and the Gamindustri Guild forces are surrounding Station Area, together with the CPUs." White Brave told them.

"Thank you for the news CPU White Brave. Come on Loweeian, lets get going!" The Lastationer woman said to her before running to the left.

"Wait up! My legs aren't used to running and still tired. Wait!" The Loweeian woman shouted in vain as she runs after her, leaving the CPU Braves behind.

"Shouldn't we help them?" Black Brave asked.

"Nah, they'll be fine." White Brave replied. "Besides, the way they are going is safe and we already cleared of those enemies for our forces to enter here to clean up this roman knock-offs."

"Speaking of, who are these soldiers and where do they come from?" Black Brave looked at the dozens of bodies in the streets that the two women killed, including few beasts men.

"Who knows, we'll find out about them when this is done." White Brave then activated his wings. "Come on! Let's find more of these soldiers trashing around. I want to let them taste of my blades before this is over."


Back at the Imperial Camp, The 7th Legion prepared to stood their ground as the enemy forces approaching their encampment from all sides. Not just in the front, but in the back of the Gate too.

Legate Decimus and Colt Formal were shocked by this outcome. They come here to conquer this world for the Sadera Empire. But as soon as they march towards their citadel, they were stopped by the citizens of this city who possess powerful weapons and iron beasts that can cut down any army and mages in seconds. What's more, reports coming in that a couple of apostles descended from the skies and decimated almost of their invasion forces, including many of the generals leading it.

Those that survive immediately runs back to the base in horror, with one wounded general barely managed to report to the legates about the fate of their legions and the enemy forces heading to this base before he died from blood lost.

Which led to their current predicament.

Once they saw the enemy forces and several iron beasts in their front and back, their few remaining generals ordered them to form a shield wall around their base and prepare for the imminent battle.

A battle that would never came.

As the Imperials stood their ground, a flying purple metal beast flying towards them and then stood still in the air. It was speaking an language that they don't understand. Imperial archers fired their bows and mages shoot their spells towards the flying beasts only for it to dodge their attacks effortlessly.

The flying beast retaliated by unleashing a strange lightning jet that, rather than burn their victims alive like any dragons, it simply vaporizes the archers and mages to the point that their bodies never existed, save for some small, burnt pieces of their bodies that survived. It didn't stop there, the beast near-vaporizes the Imperial shield wall formation before it spews some kind of lightning balls from its wings to the back of the Gate, destroying almost of their forces there. The beast then departs from their camp.

The sheer horror of their fellow Imperials being killed by a Outworlder beast demoralized not the only the remaining Imperial defenders, but also to the Legates as well. Some Imperials soldiers pleaded for their superiors to return back to the Gate, with few of them running towards it, ignoring their orders to stop.

But despite seeing the blood bath with their own eyes, Legate Decimus and other Legates refused to retreat. Knowing that doing so, would saw it cowardice by the other Imperial legates. Worse, they would be taken prisoners by the Outworlders and be tortured, same as those Imperials who got captured by their enemies. Thus, they would rather die in honor in battle than face either punishment.

So the legates ordered what remains of their Imperials forces to form a shield wall again and prepare themselves for what they believe to be their last stand against the Outworlders.

"Colt Formal, we must make our stand here." Decimus declared as he put his imperial helmet in his head.

"What!" Colt looked at him in disbelief. "Do you saw what happened?! We have attacked their city and, in turn, angered their apostles. We must retreat at once Decimus!"

"Its Legate Decimus to you!" Decimus unsheathe his sword from his belt as Colt pulled his own sword as well. "And I don't take orders from a lowly noble! If you run away from this battle. I will tell Emperor Molt that you have abandoned the empire. Your Kingdom and your children will be…!"

"Decimus! Our shield wall!" The 5th Legion Legate yelled. "Its broken!"

"What?!"

Decimus looks back and saw that the shield wall once again was broken. This time though, it wasn't that flying beast from earlier. But rather it was…

"AGRH!"

To Colt, the Legates, and the other surviving imperials' horror, they witnessed Decimus impaled by a giant sword before being cut down in half by a purple-haired young woman. Not just any young woman, those that survived from the invasion force recognized as the apostle woman who destroyed almost of their brothers-in-arms, along with that other white-haired woman besides her.

The purple being or an apostle in front of him, pointed her sword to the remaining Imperials. "Surrender now or suffer the same fate as him."

While Colt and the rest didn't know the language of this being, he knew she was asking for their surrender. Looking at the arriving enemy force from both sides, he realized that this battle is now over. He put down his silver sword into the ground and knelt down with his hands behind his back. Not for long, the rest of the soldiers and remaining demi-beasts shortly follow him. Even the die-hard Legates throw their swords away and surrendered by kneeling in the street with the others, albeit reluctantly.

While the enemy force moving them, possibly to capture and enslave them, Colt Formal could only thought about his own daughters, especially to his younger daughter; Myui.

"I'm sorry Myui, I can't come home."


It took a hour of fighting, but it is clear that the Empire has lost this battle and their forces surrendered to the Planeptune's and Gamindustri Guild forces. Thus, the Battle for Planeptune has come to an end.


A/N: The Battle of Planeptune is over and the Imperial's 'expedition' force was defeated by the CPUs and their armies. Now, they will deal with the aftermath.

To summarize of the world of Hyperdimension (at least in my universe): It is a heavenly realm; one created and ruled by a single deity before splitting it to her Daughters. In this case, the True CPU Goddess Arcadia created Celestia and later Gamindustri, before giving the latter to her two daughters; CPU Orange Heart and the CPU Blue Heart while she ruled over the former. It marked as the 1st Gamindustri Era until Blue Heart became the Dark Purple Heart by killing Orange Heart out of jealousy and tried to challenged the True CPU Goddess before she was defeated. She was sealed for millenniums by her mother until the start of the Dark Purple Crisis.

In the present day; Gamindustri is a world where magic and technology co-exist with each other. Planeptune is a combination of both. Lastation is more focused on technology than magic. Lowee is home to magicians and uses more magic than technology. Lastly, Leanbox is the most advanced out of all nations. Ultradimension follows this same logic as well. Gamindustrians always have magic within them since their creation, but it always kept in dormant state and the user can awake it if they choose to become a magician or not.

Unlike any Mortal Realms, any natural resources on both heavenly realms (Hyperdimension and Ultradimension) would regenerate up to 1 to 3 days, with Sharilite crystals regenerate up to a week. Monsters would re-spawn up to 1 to a week, depending on the creature's rarity, while animals only re-spawn for a day.

For Hyperdimension: (Still Work-in-Progress, will put in profile)

- Planeptune's military arsenal and equipment is based on: Phantasy Star Online 2: New Genesis, and Special Tactical Anti-Gang Unit (STAG) from Saints Row the Third.

- Lastation's military arsenal and equipment is based on: Resources Development Administration (RDA) from the Avatar movie & game series, and Cyberpunk 2077 (except Arasaka and other Asian-related companies).

- Lowee's military arsenal and equipment is based on: Earth Defense Force from the Red Faction series (The EDF name was replaced with Lowee Armed Forces or LAF for short).

- Leanbox's military arsenal and equipment is based on: Allied Nations from Red Alert 3: Corona & Remix (Only Remix structures, units, and protocols), Titanfall series, and UNSC Maritime Operations from the Halo fanon (written by Distant Tide).

After the Gamindustri Union was formed, the nation's military arsenals were combined into one and was shared by all members.

For Ultradimension military arsenal and equipment, they once used an energy rifle capable of shooting different elemental energy such as fire, electric, ice, and wind (Lowee Soldiers from Hyperdimension Neptunia Re;birth 1 and Leanbox Soldiers from Hyperdimension Neptunia Re;birth 3). After starting relations with their Hyperdimension counterpart though, they later discarded them and were allowed to trade their arsenals from them and mass producing them with their own factories.

Now for the reviews:

Xeno6804: Thank you, it was necessary in case I don't make a prequel.

end5: Thanks for the support! :)

JoshHCA: Correct on both accounts, though Gamindustrians required training to fight in self-defence since after the Dark Purple Crisis to protect their world in case any CPUs is out of commission; whether be in the Gamindustri Guild or not.

faturandi37: Of course.

Guess 107: No. If a certain franchise is mention in my Universe, such as the arsenals above, will not exist; general or specific.

They know that as they grow up, same as we do. Earth would not join the Gamindustri Union, but rather .

No, Gamindustri has boys and girls, same as Earth. Gamindustrians are physically stronger than Earthlings and their magic surpasses that of Falmart. That's all I could say.

We'll see.

Nuke: Yep.

Now that's done, thank you all for reading and don't forget to reply about this chapter. Although a little late but… Happy New Year 2023 to all! :D

Notes:

1. The uniform Planeptune's officers wore is the same as in Hyperdimension Neptunia: The Anime - Episode 1, albeit in male version.

2. Ram & Rom's teenage appearance, as well as their CPU forms, is based on Adult Alternative Rom and Ram (written by weresdrim).

3. CPU Brave forms is based on Sam Flynn's Light suit from Tron: Legacy, but different color schemes based on the Hyperdimension CPU girls form and without the disc attachment on their backs.
