## Background

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

After the Demon Lord's escaping from the land of Chirius, the Imperial Japanese 2nd Division and Fleet of the Otherworld Western Force continued chasing the Demon Lord's Army towards the land of Topa for long months. During the same time, the 1st Division and Fleet of the Otherworld Eastern Force continued chasing the Yellow Orge's Force, who escaped from the land of Derol. They reunited in a bridge connecting to Grameus and began their all-out attack on the Demon Lord's Army.

### Demon Lord's Army

When the Demon Lord's Army arrived in the land of Topa, the Yellow Ogre, the Red Ogre, and Malastras joined up with them. Riding on the back of the Red Dragon, Demon Lord Nosgorath and his sub-commanders ran to the land of Topa with the Imperial Japanese 2nd Otherworld Western Force hot on their heels. Starting over a week ago, they had been probed by the Zero fighters at a frequent rate, making them feel that they soon started an all-out attack. Since the emissaries also seemed to want them to go to the land of Topa, Nosgorath, who had already decided to retreat to Grameus, found it convenient.

However, it was at the land of Topa that the Emissaries of the Sun God would begin their all-out attack.

## Battle

### Offensive on the land bridge of Topa

Countless intense explosions broke out from the north and south, making it seem as if the world itself was shifting. Behind them, the Type 97 medium tanks, Type 95 light tanks, and their explosive shell forces finally appeared again, showering them in a barrage of explosions, shockwaves, and flame the intensity. From the sky, the Aichi D3A Type 99 dive bombers and Zero fighters dropped the lumps of metal-containing explosive bombs on them relentlessly, wiping out any surviving goblins and orcs in the blink of an eye.

At this point, the Red Dragon could only project its protection up to its head. Nosgorath, traumatized from his close call with a 14cm shell, had no intention to fight in the first place. The growl of engines coming from the sky got hopelessly louder as they got closer. The sound deeply etched itself in the depths of the hearts of Nosgorath and the ogres.

Alliance Commander Galeos, sitting in the back of a command car, stated to 1st Division Commander Matsushita that they couldn't hit them after all unless the Red Dragon ran out of magic. 1st Division Commander Matsushita and the others, who had waited for the 2nd Division in the south of the land of Topa, hurriedly unified their forces. For one last time, Matsushita, Kasai, Tanaka, and the others took command of their respective fronts in the operation. There was originally a suggestion to have Luca neutralize the gravitational field around the Red Dragon, but it required Luca to be near for her to pull it off. To have a group of mages, let alone a lone woman, get close to a place where they concentrated their bombardment was a no-go for the Japanese. They instead, as Galeos suggested, opted to exhaust their munitions to get the Red Dragon to exhaust its remaining magic, but soon, Demon Lord Nosgorath, the four ogres, and the red dragon ended up escaping.

However, 1st Division Commander Matsushita rejected Galeos' plan for chasing the Demon Lord and his sub-commanders to Grameus after letting them escape and run free.

## Aftermath

At the end of the land of Topa after the Demon Lord's Army was annihilated, only Demon Lord Nosgorath, Malastras, the four ogres, and the red dragon survived and retreated to the Grameus Continent.

The halves of the Alliance and the Japanese were finally able to see each other again after fighting endlessly for two years. When the commanders held the meeting under a simple tent, they discussed constructing a great wall across the isthmus in Topa. There used to be a kingdom that stood here which went by the same name, but time and time again, the relentless raids by beasts and monsters caused them significant casualties. Since the Alliance of the Races sought to reinstate the kingdom here again as the shield of mankind, they wished to construct a great wall to keep these beasts out. Galeos wished for Kasai and Matsushita to assist them in this endeavor, to which they agreed.

Three months later, after the Alliance of the Races with the help of the Imperial Japanese began the construction of a great wall across the end of the land of Topa, they completed the Doors of the World. It was 20m high and span of 100m. Designed by the Imperial Japanese Army’s engineers, it was made out of stone and woodcut and processed by the dwarves, carried to the site by beastmen and the transport ships of the Imperial Japanese Navy, and built on-site by everyone. Using wood as the aggregate, they filled in with cement handcrafted by Japanese Kaneko Muneatsu himself after carefully rubbing the parts linking the stones with each other, making it one of the strongest and most durable structures in the world at the time.

After the formalities, the Japanese went back to their respective ships aboard their launches. The farewell had finally come. The Kaga-class aircraft carrier Tosa was the first to head into the whirlpool on the north side of the isthmus. Respectively, the Akagi-class aircraft carrier Ikoma made the first entry into the whirlpool on the south side. The sailors, soldiers, pilots, and others were on the decks of the ships, waving back to the people of the Alliance of the Races on the shore, who were returning the favor with shouts of goodbyes. Once all of the nineteen ships had entered the whirlpools, the whirlpools shrank before disappearing completely.

Nine months later, after the emissaries were gone to Earth, the 1,000 strong soldiers of the last group of the Alliance called the Demon Lord Extermination Army under Commander Esperanto with Ta Lou, Kenshiva, Luca, and Kijje departed to a wasteland Guradoah roughly 4,000km from the land of Topa. Their goal was to defeat the Demon Lord in the heart of the Grameus continent.
