It has been three years since the married heroes, Saito and Louise, left Halkeginia to live in the other world where Saito was first summon from. During those three years, the rulers of the countries have formed a united nation where Queen Henrietta and Queen Tabitha, also know as Queen Charolette created a peace treaty with the Elves. Once the treaty was formed, the humans and elves began to understand each other more. Some of them were positive and some were negative. No matter the flaws, it was still the same to everyone. They see the married couple as a symbol of peace, despite the fact that they have left Halkeginia to live a peaceful life back at Saito's home world in a country he calls Japan.
Even if the countries have united, that still doesn't take away the fact that the Halkeginia is safe. There are still petty thievery and drunken brawls to deal with, plus they have gangs forming corrupted businesses hidden from the government's awareness. Not even magic could reveal their evil plots. But once the people sent their complaints to the rulers, the guards began their investigation of the crimes. Many houses of rich folks have been robbed, even the Tristanian Academy of Magic has been robbed. All the robbery was for either information or for rich goods. One of the academy members said that her best necklace had been stolen.
It's not just the thievery that's been going about in Halkeginia. There's also murder of individuals taking place and deadly messages sent to the people. There had also been murder of children and their corpses being sent to their parents. The murders usually took place at night, whether at home or out in the streets. Not even locked doors could keep people safe.
The situation gets even more dangerous when the combination of the two comes together, especially with the use of magic. Heavy Guard Duty was authorized. All the locals are to have a personally security guard to watch over their homes over night. No matter, even the guards are robbed of their goods or killed. They needed to find a way to deal with the situation before the people would form an uproar or these businesses would overthrow their government.
It was time to call for help and Saito's home world should be the perfect place to start. Headmaster Osmond and Professor Jean Colbert did their research on how to make an eclipse in order to travel into Saito's home world to contact the married couple. Their research eventually became a success. They cast a magic spell that would create a fake moon over the sun. To make sure that the experiment would work, they sent a bird to fly into the moon to get to the other world. Nothing had been heard from the bird since but they did saw the bird disappear the way the iron dragon did when its comrade was left behind to be discovered by Saito.
When the bird came back, Osmond and Colbert decided that it was time to explore Saito's home world and contact him. But as Colbert takes off in his ship along with his students. But before they can approach the portal, another ship arrives. It looked similar to the ship that Saito used to fight the dragon that could have destroyed all of Halkeginia. Only this time, the ship looked much larger. Colbert assumed that Saito might be piloting the plane. He hails the crew but he doesn't receive an answer. All he sees is the ship flying away from his. Saito would greet Colbert back if he was the pilot so something didn't seem right. He will have to inform Henrietta and Tabitha about the unknown aircraft. Whatever is in that ship or whoever is in that ship, none of them could be Louise or Saito. Hopefully, they could be the key to saving Halkeginia from this murderous crisis.
