Looking at Mimori, who had gone to sleep, Haru took out his laptop directly and started to research this world more thoroughly. He knew from their conversation before that there was an existence of a demon, which meant there should be an existence of magic or supernatural-related matter. However, he wasn't in a hurry to find out the matter of this world and decided to search for information regarding Magna Ataraxia Research, or MAR.

It didn't take a long time, and Haru found out many things about this giant conglomerate.

If Haru had to give an example, then MAR would be similar to Sony in his original world. If Sony was a giant in electronic products, then MAR was a giant in a sorcerous product.

'Sorcerous product, huh? In other words, a weapon, huh?'

Haru shook his head at this company, but he didn't think too much and checked the information of shareholders of MAR. He checked for a bit and felt that it wasn't that difficult for him to control this company.

After he checked the MAR, then Haru checked what was Itogami Island since it was the most important matter that he needed to check now. In his quest, he needed to rule over this island and also created a kingdom, empire, or country, considering the situation of this world. Then without hesitation, he searched all the information about Itogami Island, and he had to admit that he was a bit dumbfounded.

Itogami Island is an artificial island floating in the middle of the Pacific, some 330 kilometers south of Tokyo. It was a completely man-made city, built from a linked series of giant floating constructs known as Gigafloats. Its total area was approximately 180 square kilometers, holding a total population of around 560,000.

'An artificial island, huh?'

Haru had to admit that this island was interesting, especially when he knew that it was constructed over an intersection of ley lines known as Dragon Veins which consists of massive spiritual energy.

A keystone was needed to control these ley lines, and this keystone was the right arm of a dead saint from the West European Church.

Reading the information in front of him, Haru could only sigh, and he was sure that it would cause a lot of trouble in the future. He could probably guess that someone from the West European Church might come to Itogami Island and destroy the island since the creator of this island had stolen the right arm of their saint.

However, it wasn't his problem, and he didn't care much since he was sure that the main protagonist would take care of this problem.

'Still, who is the main protagonist?'

Haru glanced at Mimori, who was sleeping so soundly, and caressed her hair gently, which caused her to smile. He somehow had a feeling that the main protagonist might be Mimori's son, but well, it didn't really matter for now since he needed to know more about this island first.

Itogami Island was originally Japanese territory. It was administratively known as Itogami City and was part of the greater Tokyo metropolis, but in reality, it was a special administrative district with an independent political structure.

'So to rule this island, I need Japan to relinquish the right to manage this island, huh?'

Haru felt that it wasn't that from him to make Japan relinquish the right to manage this island, considering many problems that might appear on this island sooner or later.

Haru knew that the main character had always been a magnet of trouble, and he knew that there would be a lot of trouble that would come to this island that made Japan would relinquish the right to manage this island, then once Japan relinquished the right of the island, then he would create an Empire directly. Anyway, Itogami Island was located in the Pacific Ocean, which meant he could expand this island as much as he wanted.

As for money, it was the last thing that he needed to worry about since if someone asked what he lacked, then he might lack a lot of things in this world, except for money since, as for now, he kept making money at ridiculous speed.

'First, I have to buy MAR and create a bank.'

Haru threw the matter of the money aside, then thought about the matter of specialty of the Itogami Island. Unlike Japan, which was mostly dominated by humans, in Itogami Island, both demons and humans existed next to each other, and they lived together on this island peacefully.

Well, Haru couldn't say that it was fully peaceful, considering there were still a lot of crimes that happened on this island, especially when demons' power was different from a normal human, and they could cause a lot of casualties when they were fighting each other, but this island was mostly safe, considering the security on this island was very top-notch, especially when he saw that there was a special prison, which was managed by the "Witch of the Void," Natsuki Minamiya.

'Legal loli, huh?'

Haru looked at the picture of legal loli on the screen of his laptop before he continued to search for research information about this island.

Itogami Island has five main districts, North Island, South Island, West Island, East Island, and a Center Island connecting the four and providing the foundations for the city. The four surrounding Gigafloats represent the four divine beasts and their ruler at the center, which are linked together in an attempt to control the Dragon Veins. North represents the Black Tortoise, south represents the Vermilion Bird, west represents the White Tiger, east represents the Azure Dragon, and its ruler, the Yellow Dragon, represents the center.

The North Island houses the northern R&D district, with corporate labs lined up one after another.

West Island is described as a city that never sleeps. It is stated that many restaurants and business establishments were gathered here, with most stores continuing to operate until daybreak. Island West is also a popular destination for demonic residents due to the wealth of services geared toward them and is a symbol of Itogami City and the peaceful coexistence of humans and demons within.

South Island is the main residential district from rich in residential housing and educational facilities, even a research and development district covered with corporate and academic facilities.

The East Island contains a warehouse district and an industrial area.

Itogami Island is fundamentally made up of four Gigafloats, but the island also has numerous smaller extension units all around it. They fulfill various functions, such as floating crude oil depositories, dry docks for repairing ships, or serving as a giant dumpster for the storing of non-flammable waste.

Lastly, there is a Keystone Gate. It is a giant composite structure two kilometers in diameter, located at the center of the island, binding the four Gigafloats that compose Itogami Island. At twelve stories, its aboveground section is the tallest building on the island. Within the facility are government administration offices, including city hall, and numerous hotels and commercial facilities built one after another, functioning as the island's nucleus.

'This Keystone Gate has 40 levels beneath the surface, huh?'

Haru knew that there must be a secret under the Keystone Gate, but it should be easy for him to sneak in later. However, it wasn't necessary for now since there was something that he needed to do first.

Based on the information, he should be on the North Island, considering Mimori was the head researcher of MAR's medical department. Rather than staying in the South Island, it was better to stay in the North Island, considering her safety and the confidentiality of her research.

Haru had finished his research about the Itogami Island, and he needed to know the matter of the demon, but when he was about to do his research...

"Hmm... what are you doing?" Mimori, who had woken up, asked with a yawn, staring at Haru curiously.

"I'm learning about this island," Haru said simply.

Mimori blinked her eyes and asked, "You can do hacking?"

"Um." Haru nodded simply and didn't see a harem to tell this woman.

Mimori didn't move from her spot and asked, "Do you want to teach you more about this world?"

"Why did you treat me as if I'm coming from another world?" Haru asked weirdly.

"Because your technique was otherworldly," Mimori said with a blush.

"......"

Haru wasn't sure what to say for a moment, but that should be praise, and he should be happy, right?
