-Next three days-

-Five km form Userius Mountain-

Vault, former soldier of the Imperial Army, now lord-commander of the Blackdogs, wearing his armor with broadsword on his back observing the Userius Mountain whilst on his horse while his army march on. (From Kuroinu: Kedakaki Seijo wa Hakudaku ni Somaru?)

"Commander!" A horseman name Kin, second-in-command of Vault, called out making the sellsword commander turn to look at him. "We have spotted what appear to be enemy scouts ahead." He said as he point the hill. "Leave them be." The commander said making the horseman look at him as he rode to join the army. "Let's meet the others." (From Kuroinu: Kedakaki Seijo wa Hakudaku ni Somaru?)

In the front is massive army camp, as night falls while inside the tent where lord-commanders from different mercenary companies, Imperial generals, vassal kingdoms of the Empire: Lockland, Valdland, Big Shimaron, Asteria, Bastarauge, and Svelera are discussing the battle tomorrow.

"I, Henry, King of Bastarauge will take the frontline!" Henry proudly said as he pound his fist onto his armor chest. (From Slutty-Princess Diaries)

"No, I should take the frontline!" Franchesco Chench shouted as he drank the golden goblet of wine then burp loudly as the others disgust the Big King of Svelera. (From City of Sin)

"No, I am!" Belar, King of Big Shimaron, shouted. (From Kyou Kara Maou!)

"I am!" Agamar Balbacil, King of Vadland, shouted as well. (From Elufina - Inyoru e to Urareta Ōkoku de. . . The Animation and father of Viceard)

THUD

"Like you royal fancies will have the glory without us, the Outsiders, and the Blackdogs will join the frontlines as well!" Marek roared as he pound his armoured gauntlet fist the table as Vault, the commander of the Blackdogs, while cross his arms then he grin of his colleague's statement as other lord-commanders agree.

"Gentlemen, we shall meet tomorrow at Userius Mountain." The Imperial general said as mercenary lord-commanders, generals, and the other vassal kings left the command camp.

"I can't wait for glory tomorrow." The King of Asteria, Han, said while Agamar only just laugh loudly as he agree with him. (From Slutty-Princess Diaries)

"Our enemies army at Userius Mountain are more than 30,000 soldiers. While we have an army of 250,000 altogether." Philip, King of Lockland, said as he sigh with his eyes closed as he return his tent. (From Attack of the Gryphon)

"It will be a glorious battle, Lord Franchesco." Belar told to the Big King with a smile on his face. "We'll overrun those newcomers with one swift blow." He laughed.

"We'll get a huge spoils for our glorious victory, and many whores to fuck!" Franchesco says, the Big King, said as he drooled with lust.

-Next morning-

The Imperial soldiers pound their swords onto their shields and stabbed their spears onto the ground, over and over, making rhythm. As Nero, the General of the Empire, riding his horse on a white charger, armed with a fourteen foot lance which the soldiers made a path way as he walk through the soldiers. Then the pounding and stabbing stopped as he face the armies of the Empire, the mercenaries, and the vassal kingdoms.

"Now here we are to fight these invaders from another world that dare confront us!" The men jeered. "Follow me, and we will destroy this enemy!" He turned around. "Then we'll have a huge REWARD!" The men cheered and roared at him.

"Forward!" The Imperial general wearing his armour shouted as he lead the Imperial army along the mercenaries and the vassal kingdoms to march for Userius Mountain.

As the Imperial Army and the vassal armies march towards the hill where they greeted by massive billboard signs which they ignore and pass them. Unknown to them, they were being observed by a BAF soldier with binocular.

The army still continue to advance as Franchesco read the script on the sign. "Keep out. For safety reason this area is not to be entered. United Kingdom of Great Britain and Northern Ireland." Various smaller signs are written under the massive signs all with the flag of the United Kingdom. The Big King just shrugged as he kicked the billboard as it falls to the ground. "Bah, like signs scares me!" He sneered the falling sign as he join the army to continue the advance.

Then a strange noise was heard, it was loud whistling noises coming closer every second. Everyone looked around in confusion as Henry look upwards in confusion when massive explosions engulfed the entire army.

Nero watches as massive explosions engulfed the armies while taking the men with it, then he saw something falling from the sky. 'What in Hardy?' It was the Big King last thought as a Highly-Explosive artillery shell fell on him then killing him and the army including Han and Henry.

"By the gods. . ." Philip muttered in horror after calming his horse down. "Is Userius Mountain erupting?"

After the explosions ended, the King of Lockland and his army rode through the smoke and what greeted them were corpses lying around, many were missing some body parts with very few survivors as the ground where the army advance was darken while the hill was untouched. At the scene one of his men became sick and understood why.

"Where is the King of Asteria? Where is the King of Bastarauge? Where is the Big King of Svelera?" The Locklander king asked the survivors came back carrying wounded survivors.

Imperial-Allied Army Camp

Inside the command tent, the generals and lord-commanders are panicking.

"We've lost 177,000 men, we set out with!" Belar said in despair before asking. "How could this happen?" He asked the rest.

"Not even the orcs, or the ogres could stand a chance against them!" Kin, second-in-command, shouted.

"By the gods, are they sorcerers?" An Imperial officer said while his head and left-eye covered in bandage.

"I'm out of here!" Agamar shouted as he left the tent.

"I have enough of this senseless slaughter, I'm withdrawing my army back to Lockland!" Philip shouted as he left the tent while the Imperial officers shouted the King of Lockland to come back.

"Should we not retreat?" The Imperial general said as he sigh.

Vault spoke. "We cannot run off now." As the remaining lord-commanders and kings gasped. "Not before I repaid them with my sword."

"But Lord Vault, we have hardly enough fight!" Marek pointed out. "Perhaps a night raid." The Blackdog lord-commander suggested.

XXXXXXXXXX

As the night starts to fall he explain one of his captains. "Tonight is a new moon. In this darkness, we should be able to make it to the other side of the hill and ambush them the enemy." He said as he saw the remaining Imperial, vassal kingdoms and mercenary armies trying to advance quietly. Unknown to them, they're being watched by a BAF soldier attached of night vision goggle.

"Be quiet." An Outsider officer said.

An Imperial officer said. "Move lightly." Suddenly the night sky light up by flares, all of the soldiers were surprised to see night brighten up like day-time.

"What brightness." Vault said as he look to the night-sky became day then it made him realize. "No! Men! All forces! Attack! Riders advance! Infantry advance! Advance! Advance! Advance!" As Vault charge the enemy lines, just as the tanks fire two rounds and the result killing thousands in the explosion.

"Keep going! Follow me men! To glory!" Vault charge until he came to the barbwire fence that snared his horse thus making him drop on the ground along his broadsword.

"Lord Vault!" Kin shouted. "We're coming!" Another Vault's lieutenant shouted. "Shield upfront!" Soon the men formed a protective shield-barrier formation as his lieutenants help him stand up. He saw a few flashes of light fling in the night-sky pass above them it made him realize again like the brightness before.

"Charge! Everyone, charge!" Vault ordered as he pushed his lieutenants away. Then flashes of gunfire appeared from Atria Hill as flashes dash across the field and soon men began to one after another.

Fort Wellington

Various machine guns, tanks, artillery, and Heavy Gears (Grizzly and Kodiak) of the British Armed Forces open fire rounds at the enemy advancing army slaughtering them. "All gears, begin advancing." Richard gave the order as the other gear units began advance to the enemy.

Back with Vault

As he watched his allies including his lieutenants and allies wiped out by flashes of light then he watch as a flash of light fly pass him and something pinged off his cheek then he saw the iron titans that heading straight to his direction as he slowly marched forward despite of what was happening around him around him. He then stopped and pick up a bow and arrow.

"BASTARDS!" He lose the arrow as it fly for a while before falling short of the enemy. "How? How could have these happened?" Vault ask before he began to laugh like mad man before he was thrown back by an explosion.

Far side of Userius Mountain

On the far side of the mountain. They're being watched by Fredrick Vance, the Head of House Vance, the Count of County of Vandeberg, the husaband of Maria, and father of Leina, Elina, and Claudette, he ride his horse while wearing his armor accompanied by his royal guards carrying the banner of white lion and black background. Besides him is Howard Kreutz, the Head of House Kreutz, Margrave of Margraviate of Lodenia, and father of Annelotte Kreutz as he rode his horse. (From Queen's Blade)

"It seems the rumors are true. The Imperial Army along with those foolish vassals and mercenaries are wiped out. Don't you think so, Annelotte?" Howard said as he observed with his telescope while he grunt the defeat of the Imperial-Allied Forces.

"Yes, it is, father." Annelotte as she rode her horse beside her father as she observe.

"How foolish of them." He said as he put down the scope while shook his head with disappointment then sigh. "Underestimating the newcomers' powers."

"Indeed, father." Claudette Vance, the Thundercloud-General of Vandeberg Army, respond as she rode her horse. "Very foolish of them."

Inside the carriage. "Ironic isn't, the mightyEmpire were beaten by them." Elina said in sarcasm as she giggle loudly as she put down the scope while her sister and mother just groan. "Elina!" Maria and Leina scold her then she pouted. "Sorry." She was hugged by her mother and her sister as the moon shines upon Fort Wellington.
