## Background

### Demon Lord's Army

Two months later, after the Battle of the Southeastern Philades, the Yellow Ogre continued his retreat with 35,000 demons along the coastline eastwards during Demon Lord Nosgorath continued the north along the southwestern edge of Philades. Since attacks would occasionally come from the sea, they made sure to stay away from the coastline itself. However, their food provisions were rapidly deteriorating. They could neither spare the time to attack the villages that seemed to be neither populated nor could they even hunt wild beasts. They would eventually have to go to the coastline to fish for food else they face death. At any rate, they’d still end up dying. They initially had 35,000 troops since splitting up, but after a month of retreating, they had lost more than 3,000 to attacks from the emissaries. Since their relentless attacks hardly loosened, starvation and exhaustion naturally led to the deaths of many. If this goes on, they would likely lose much of their force in the coming three months. The Yellow Ogre at the very least wanted to prevent the unnecessary death of the troops that the Demon Lord had entrusted upon him.

One month later, the Red Ogre and Malastras, who had crossed from the Rodenius continent, joined the Yellow Ogre with 32,000 demon troops. They marched toward the Topa through the land of Derol in the eastern of the Philades continent. However, the 1st Otherworld Eastern Force approached nearing the far end of the land of Derol before starting the battle with the Demon Lord's Army.

### Emissaries of the Sun God and Alliance of the Races

After a force of 10,000 Alliance warriors under Commander Galeos made his way to the Rodenius continent last several months, Warriors Commander Ta Lou left with only 300 warriors for his chances of survival. They encouraged each other, protected one another, and fought the Demon Lord's Army together. After defeating the Demon Lord's Army in the southeastern coast of the Philades continent, 1st Army Division Commander Matsushita Takao joined in on searching for a Band of Warriors with Kenshiva’s request, who possessed intimate knowledge of the land led them when the Imperial Japanese Army’s Otherworld Army Division split the west and east.

Two months later, as the Yellow Ogre worried, Ta Lou and the 286 warriors shadowed him before heading back to a human refuge at the village of Laterre in the land of Doria. He discussed with Warriors Vice Commander Mareja their plan. Mareja explained that the Yellow Ogre headed the Derol as he pointed out on the handmade map. Ta Lou intended to follow the Yellow Ogre, who despited being persistent in rooting them out, suddenly ignored them and diverted somewhere else. On that day, Ta Lou’s band of warriors offered their gratitude to the people of the settlement before setting off.

One month later, in the Derol in the eastern of the Philades Continent, another game of tag has begun. They had ordered to not mount an attack on the Yellow Ogre without wasting too much ammunition. However, since the armor and infantry units had split up to each harass the Yellow Ogre’s forces so that they didn’t get too much time to scavenge for food, the beasts had died of starvation increased. At the rate that they’re going, they could effectively shave off the majority of the Yellow Ogre’s forces before they could even reach their destination.

Matsushita left command of the 1st Army Division to his subordinates while he, Kenshiva, and several soldiers set out to search for survivors from the Alliance. Since vehicles could not travel long distances without refueling gasoline, they opted to travel by horse instead. They flinched at the towering heights of the mountains on the horizon. Up to that point, all they came across were endless grassy meadows, dotted with the occasionally slopey hills that protruded from the plains. Kenshiva pointed the grass in the area where the trampling of the beasts of the Demon Lord's Army was closing to the Derol. Moreover, Ta Lou would not hesitate to enter the mountains up ahead. So they travel into the mountains on horses.

Ta Lou, leading his warriors, had taken descending the route from the mountains, but he stopped them and heard the sound of horse roughly 200m south. Kenshiva reunited Ta Lou and Mareja past the fringes of the forest and introduced Matsushita and several soldiers as the Emissaries of the Sun God. Matsushita and Kenshiva then explained what had happened: Orlaxle’s demise, the elves’ desperate prayer and unexpected response, Matsushita and the rest of his comrades summoned from their world, their current counteroffensive, and Galeos taking the western route. After hearing about Orlaxle’s demise, Ta Lou, Mareja, and the other warriors with them all shed tears. However, when they heard about Galeos being still alive, they exhaled sighs of relief and joy. With their plan to annihilate the Demon Lord's Army in a bridge connecting to Grameus once and for all, the Band of Warriors joined them. Matsushita’s 1st Otherworld Division headed northeast to link up with the 1st Otherworld Deployment Fleet.

## Battle

### Battle of Derol

In the rainy morning, nearing the far end of the land of Derol, Ta Lou allowed accompanying Matsushita, who followed the armored battalion from behind since he wanted to see how the Japanese army fights. Matsushita, Ta Lou, Kenshiva, and four of Mareja’s warriors watched the infantries and armored battalions fight it out with the Demon Lord's Army. As Matsushita and the others ran and battled them, Ta Lou and Mareja were right behind them. They, who didn’t seem to mind the rain, nonchalantly walked away.

### Red Ogre's Surprise Attack

Ta Lou and Mareja noticed it at the same time, but Mareja moved first. Suddenly the Red Ogre protruded his dark red arm through Mareja's chest. Malastras, standing right behind the Red Ogre, confirmed that the two were still alive despite their long absence. Ta Lou had already drawn his sword, which if the Red Ogre were still where he was a moment ago, he would have already cut the massive beast down. Kenshiva and Matsushita, having heard Mareja’s scream, came running back. Kenshiva then ran to the fallen Mareja and tore open his bloodied raincoat. It was already clear to everyone that he was beyond saving. His heart was gone, replaced by a hole from which blood sprang forth.

His life ebbed away in front of Matsushita and Kenshiva. He had fought up to this point without ever being bested by anyone. However, it seemed to be merely due to luck. Letting his guard down for a moment, he then lost his life. Forgetting this simple truth would have likely been due to arrogance.

The imperial soldiers that have now appeared around Matsushita readied their Type 99 rifles. Their firepower might not kill the Red Ogre then and there, but they could kill Malastras. Furthermore, the Red Ogre has to mind both Ta Lou and the Imperial Japanese soldiers. Malastras neared the Red Ogre, taking cover behind him as he reminded him of their priorities. The Red Ogre anticlimactically softened his posture. Malastras and the Red Ogre zoomed away.

Finally sheathing his blade, Ta Lou then ran over to Mareja to close his eyes. The rain ceaselessly poured on everything, slowly draining the heat out of everyone’s bodies.

## Aftermath

After losing more demon troops to attacks from the emissaries, the Yellow Orge, the Red Ogre, and Malastras and the remains of his army had escaped the land of Derol. They continued northward along the eastern edge of Philades continent to the land of Topa other long months until reunited Nosgorath, the Blue Ogre, the White Ogre, and the Red Dragon who escaped from the land of Chirius, in the land of Topa, joining them to retreat to the Grameus Continent.

The Imperial Japanese 1st Otherworld Eastern Force traveled to the land of Topa, reuniting with 2nd Otherworld Western Force and joining them together in the final battle against the Demon Lord's Army in a bridge connecting to Grameus.
