Genjitsushugi Yuusha no Oukoku Saikenki

The manami, or demon wave. It was a phenomenon of monsters appearing en masse from the Demon Lords Domain and moving south.

The second year after Souma assumed the throne, the 1,547th year of the Continental Calendar, was the year that the third demon wave after the Demon Lords Domains appearance broke out.

In cases where monsters overflowed from a dungeon, even if those monsters formed groups, there were, at most, several dozens of them. But in the case of a demon wave, over 10,000 monsters would suddenly invade the nations of mankind.

Naturally, unlike when they emerged from a narrow dungeon, the monsters would be scattered across the border as they invaded, so there would be fewer monsters on any given battlefield, and the pressure put on defenses would vary from place to place, depending on the monsters weakness or strength.

However, if thousands of powerful monsters invaded at once, a small country would be mercilessly trampled underfoot, and a medium-sized country would likely face an existential crisis.

One of the locations seeing heavy fighting in this years demon wave was the Kingdom of Lastania on the northwest edge of the collection of small- to medium-sized countries known as the Union of Eastern Nations.

This country had a population of under 20,000 and a force of merely 500 career soldiers, but a swarm of over 5,000 monsters was now bearing down on it.

Most of them were lizardmen, which had lizard heads and scaly upper bodies that were humanoid, but their legs more in line with a small beast. (If one were to compare them to a dinosaur from Soumas world, the closest would be a deinonychus.)

Their name may be lizardmen, but their actions were purely bestial in nature, and there was no sign of the high intelligence said to be possessed by the demons.

There were also countless chimeras lurking around near the lizardmen.

The number of these monsters was more than the Kingdom of Lastania could handle alone, but both the Union of Eastern Nations they belonged to and the Nothung Dragon Knight Kingdom they were allied with were being affected by the demon wave and were too busy attending to their own problems to be able to send help.

So, in response to this situation, the Kingdom of Lastania gathered the people who had been unable to escape southward in time to the countrys sole walled city, Lasta, and settled in for a siege.

Unfortunately, the Kingdom of Lastania only had a regular army of around 500 men, and even with another fifty volunteer soldiers, they still had fewer than 600 men in total. These werent numbers that could repel over 5,000 monsters.

To make up for that, they conscripted 3,000 combat-capable men from the 10,000 citizens they had taken in and assigned them to guard the castle walls. This brought the number of defenders up to 3,500, but most of them were ordinary people. A common person couldnt take on even a weak monster alone, so it was fair to call their situation desperate.

But the Kingdom of Lastania was still doing a good job of holding out.

Noon of the 15th day, 10th month, 1,547th year, Continental CalendarOn the walls of Lasta

Archers, take aim! Theres no need to target distant enemies on the ground! Focus fire on those climbing the walls and be sure to hit them!

Julius was giving commands at the southern gate of the walls as they were attacked by lizardmen.

Julius was a visiting general in this country, but no one in this land was a more experienced commander than him, so he had temporarily been given total control over the forces of Lastania.

Before Juliuss eyes, he could see soldiers focused on the enemies that had approached the gate. They had arrows nocked and turned toward the gate that must not fall.

Julius hurriedly shouted at them. You fools! Focus on the enemy in front of you!

No, but if the gate were to fall... one of the soldiers began objecting. Uwah?!

His legs gave out as a lizardman poked its head through the arrow slit in front of him. It had climbed up the wall.

The lizardman stood before the soldier, who was too shocked to regain his footing. It flicked its lizard tongue and opened its mouth wide to feed on the soldier.

Eek! The soldier raised his arms to cover his face in abject terror.

In the next instant, the dull sound of something piercing flesh reached the soldiers ears. However, the man didnt feel any pain, so he hesitantly dropped his arms.

There was a single saber piercing the lizardman through the mouth.

...I warned you, Julius said.

It was his saber piercing the lizardman.

Julius pushed the lizardman against the edge of the wall along with his saber. Then, kicking it in the torso, he sent it over while tearing his saber free. The dead lizardmans body fell straight down the outside of the wall.

Eventually, realizing he had been saved, the soldier looked up to Julius. Th-Thank you so much!

...Hmph. Julius swung his saber, flinging the lizardmans blood from it, then raised his voice once more. Listen! The enemy is not fighting a siege! The ones surrounding this castle dont have the intellect to enter a house through the front door to begin with! They try to climb both the walls and the gate! Thats why you should all focus on the enemy in front of you!

Yes, sir!

Impressed by their commanders show of bravery, the soldiers morale went up just a little.

The soldiers fired on the lizardmen as they tried climbing the walls and knocked them down with thrusts of their spears. The sight gave Julius a moment of relief, but he continued shouting.

Thats the way! Dont let up on guarding the anti-air repeating bolt throwers on the corners of the walls! If theyre destroyed, fliers will be able to cross the walls and attack those behind us!

He was referring to those warped chimera monsters that wandered around within the pack of lizardmen. These monsters were a mishmash of different animal features, and it was not possible to describe them uniformly. Some crawled on the ground, while others flew, making it more difficult to respond to them.

It wasnt that the lizardmen and chimera monsters were working together. The chimeras were scavengers. When the lizardmen attacked the soldiers, the chimeras stalked the area, looking to claim the dead soldiers and lizardmens meat for themselves.

They were nothing but scavengers so long as those around them were dangerous to them, such as the soldiers and lizardmen. But if the chimeras encountered weaker prey, they would attack fiercely.

If the anti-air repeating bolt throwers were destroyed, the winged monsters would attack the non-combatants hiding behind the walls. That had to be prevented at all costs.

One of the experienced soldiers rushed over to Julius. Sir Julius, do you think the other walls are safe?

Madam Lauren is defending the east gate, and Jirukoma is protecting the west gate. We have positioned many of the regular forces on the north side, where there is no gate. If I am being honest, the defenses are weakest here. So long as there is no breach here, I doubt they will get through anywhere else.

I see... The experienced soldier nodded in satisfaction, then returned to his post.

Eventually the sun went down, and night fell on Lasta.

Maybe the lizardmen had poor night vision, because they didnt attack at night. In their place, the chimera monsters grew more active, and while none tried crossing the walls, they feasted on the corpses of soldiers and lizardmen that were scattered outside the walls.

They couldnt lower their guards, but for the soldiers who had fought through the day, night was an important time of rest.

Julius, who had been commanding from atop the wall for the entire time, went on break too, and he sat around a campfire with Jirukoma and Lauren. They had both fought hard at their own positions, and the signs of exhaustion were visible on each of their faces.

Julius asked Lauren a question. This makes five days now, doesnt it? How many have we lost?

Lauren bit her lip. Another hundred today... If we were to tally up all the dead and heavily wounded, it would be around 600.

That meant almost a sixth of the roughly 3,500 defending soldiers had been rendered unfit for combat.

Jirukoma sighed as he maintained his kukri blades. Were at less than 3,000 defenders... Meanwhile, the enemy doesnt seem to have dropped from 5,000. Even though Im sure we killed a fair number of them today.

Julius crossed his arms and spat out his next words. It seems like more and more keep piling in from the north. Honestly, it troubles me.

The terror of the demon wave was that monsters would be replenished, with one group following another like waves. It was exhausting to think that, no matter how many they defeated, the number of enemies would never go down.

Admittedly, these were unintelligent monsters, so if too many were in an area, not all of them could participate in battle. That meant they would go past this city and move further south. In other words, while their numbers wouldnt decrease, they would never build up too much either.

Do you think the lands to the south are all right? Lauren pondered.

Were in no position to be worrying about others. Julius completely rejected her concern. For as long as we hold out here, the number of monsters going south will be kept lower. From the point of view of the countries in the south, even if our country is ultimately destroyed, Im sure they want us to hold out as long as possible and slay as many monsters as we can.

While they have their own countries and families to think of, that does feel a little heartless, Lauren admitted.

Thats just how things are. If you havent first taken care of yourself, you cant extend a helping hand to others.

I suppose youre right... Im sorry, Sir Julius, Sir Jirukoma. Lauren bowed deeply to the two of them. Im sorry for getting foreigners like yourselves caught up in a battle like this. I even have Sir Julius taking full command of our forces... I feel pathetic.

Though Lauren clenched her fists and bowed her head with a pained look on her face, Jirukoma laughed heartily and put his arm around Juliuss shoulder.

Raise your head, please, Madam Lauren. We are fonder of this kingdom than you may think. Right, Sir Julius?

Get away from me. This is suffocating. Julius brushed the other mans arm away, then loudly cleared his throat. Well...I had no time to escape south after all. As for commanding the troops, there was no one more capable than me, so this was the inevitable result. Id rather not die under the command of some incompetent fool after all.

Hahaha! You say that, but you didnt have the slightest intent of fleeing without Princess Tia.

...You talk too much.

The awkward frown on Juliuss face made Jirukoma and Lauren burst out laughing.

Light footsteps approached near the three of them. When the three looked up, a petite figure was bringing something large toward them. When that person approached the campfire, Juliuss eyes went wide as he realized who it was.

Princess, why have you left the royal manor?!

It was the princess of this country, Tia Lastania. She was wearing her usual Tyrolean-style dirndl with an apron over the top, and she held an earthenware pot in her mittened hands.

When Tia saw Julius, her face burst into a smile.

I was helping the ladies in town hand out food, she explained as she offered the pot to the three of them. Lord Julius, Lauren, Sir Jirukoma. Its bread porridge with pumpkin and milk. Im sorry this is all we have for you after youve fought so hard...

D-Dont be ridiculous, princess! We gratefully accept it! Lauren sputtered.

She saluted as she accepted the pot, and Jirukoma patted his belly with a laugh.

Were hungry from fighting after all. Im sure anything will feel satisfying at this point.

Thats a rude way to put it... Julius shook his head in exasperation, but his expression had softened slightly from before.

Then the three of them sat around Tias pot of bread porridge to eat.

Tia shrewdly sat herself down in a position where her shoulders would be touching Juliuss. That put a wry smile on Laurens face, but she suddenly returned to a more serious expression and asked Julius a question.

Ultimately, is holing up here our only option?

Now that were surrounded, escape is impossible, Julius answered in a calm tone between sips of porridge. If the enemy were sentient, we could negotiate, but they have nothing in their minds beyond eating the prey in front of them. They just repeatedly attempt to rush the walls. Thats why were barely able to fend them off. But...if this is a battle of attrition, its going to be difficult.

Lord Julius... Tia grasped his sleeve, her eyes wavering with uncertainty.

Julius put his own hand atop hers as he said, Whatever the case, we must hold out for now, whatever it takes. We will hold the city while waiting for reinforcements to come from somewhere. That is all we can do now.

The next day, the lizardmen began attacking the walls of Lasta at daybreak.

Their numbers still didnt appear to have dropped from 5,000 so it was clear another pack of lizardmen had joined up with them.

After days of continuous battle, the defenders exhaustion was building.

If this had been an ordinary siege, the attackers would have avoided pressing the attack in a way that only increased losses, seeking instead to find an opening in the defense. They would have desisted immediately when it became clear the defenders wouldnt break, trying instead to limit the damage to their own forces.

The lizardmen, however, tried scaling the walls no matter how many of their fellows fell, charging in to eat the people inside. The death of their comrades and the exhaustion of their forces meant nothing to them.

Because of that, the defenders had almost no time to relax, and they had been pushed to the edge both mentally and physically.

Even so, the soldiers of Lastania up on the walls fought their hardest to prevent a break in their defenses.

When Jirukoma was giving commands near the west gate, one of the volunteer soldiers, who were made up of refugees, came to ask him a question.

What do you think those things are thinking about when they attack?

What do you mean...what are they thinking about?

It feels like, rather than trying to take the city, theyre only trying to eat us, the soldier said. If theyre that hungry, surely they could just eat the monsters that are lurking around. I mean, they dont seem to be buddies, as far as I can tell.

Jirukoma was silent, nodding. That was certainly something he had sensed too.

The first thing the lizardmen did after scaling the walls was try to bite the soldiers. Hed seen that action as a sign of intense hunger.

Looking at the way they continued to rush the walls in search of food, no matter how many of their kind fell, they seemed to have hardly any intelligence. However, if that were true, then why didnt they try to sate their hunger on the chimera monsters that were nearby? The chimera monsters were feeding on their corpses after all.

Is there some deep reason for it...? Jirukoma wondered, then pushed the thought away. He couldnt sense any intellect from the lizardmen out there. There was likely no deep reason, and the reason why was probably incredibly simple.

For instance...

Perhaps we look tasty to them? Maybe thats why they rush to us? he suggested.

Like they think were a delicacy? the soldier asked.

Who knows. Please, ask the lizardmen.

While they were talking about that, there was a shout from a soldier near the west gate.

Sir Jirukoma! Theyre close to pushing through on the north side of the western wall!

The moment he heard that voice, Jirukoma readied the twin kukris that were his favored weapons.

The man who had been asking Jirukoma questions steeled himself, placing a hand on the hilt of the sword slung over his back.

Strike team, lets go, Jirukoma said simply to the volunteer soldiers around him, then took off running toward the northern side.

About five volunteer soldiers followed behind him.

When Jirukoma reached the center of the city, Julius and Lauren were already there.

Madam Lauren, has something happened? Jirukoma asked as he dismounted his horse.

Lauren took off her helmet and stuck it under her arm, then suddenly cried, Im sorry! and bowed her head. I just received the report, but from what the person managing the castles armory says, our supply of arrows is about to run out.

No arrows... Julius murmured.

This was a serious issue. It was only because they had ranged weapons like bows and arrows that the conscripts were able to fight. Without enough arrows, their ability to defend the walls would take a big hit.

Julius squeezed his temples. Its only been six days since we settled in for the siege. Did we not have reserves?

Its because the number of regular soldiers we had was low to begin with. We should have had enough to last for two weeks with our current numbers, but the enemy offensive has been intense. Not to mention that many of the men arent used to using a bow and arrow, so I think that made us burn through them faster. We currently have the blacksmiths in town making more, but at the rate were going through them, they cant keep up.

Its hopeless then...

Im sorry. Lauren bowed her head in despair.

Jirukoma put a hand on her shoulder. Raise your head, Madam Lauren. Surely this isnt your fault. I believe the people of this country are doing well to hold out while at a disadvantage. If it comes to it, well drop bricks from the rampart, scatter oil, and fend them off with spears.

Sir Jirukoma...

Laurens eyes were moist, and Jirukoma patted her on the shoulders to calm her down.

Once he could see Lauren had regained her composure, Jirukoma spoke to Julius. Still, if its come to this, we really are going to be relying on reinforcements. I dont suppose any of them might happen to be nearby already?

However, Julius shook his head.

With us surrounded like this, theres no information coming in. Theres little hope of reinforcements from inside the Union of Eastern Nations, so...I guess its up to the Nothung Dragon Knight Kingdom.

What about reinforcements from the Kingdom of Friedonia? You said you sent a request there, didnt you?

Even if Souma is sending reinforcements, this country is a long way from there. If we consider the pace their troops would move, I cant see them arriving today or tomorrow.

I see...

The two men frowned, then it happened.

One of the soldiers rushed over in a hurry, taking a knee as if hed stumbled and fallen over. Looking closer, he had gashes on his arm like hed been clawed.

I-I have a report, Captain!

Where did you get those wounds?! Lauren cried.

The soldier kept his head bowed and rapidly gave his report. The lizardmen rushed the north wall, and they have broken through in places! More than ten of them have headed for the castle and are now fighting the guards!

This was the first reunion between the current King of Friedonia, Souma Kazuya, and the former Crown Prince of Amidonia, Julius Amidonia, after a whole year.
