DISCLAIMER: Nihonkoku Shoukan/Summoning Japan belongs to Minorou.

The Holy Milishial Empire is a millennia-old country that spans much of the Central World and boasts one of the highest levels of urbanization, industrialization, and technological and magical progress on the entire planet. Blessed with the abundance of ruins from a civilization long gone, studying and reverse engineering these technologies, as well as the great military strength accumulated over the millennia, the Empire has acquired its place in the sun as the Central World's and indeed, the world's preeminent superpower. Under the wise and benevolent leadership of Emperor Milishial VIII, the Empire stand ready as the world's guardian for the fated return of the tyrannical Ravernal Empire.

However, the lack of meaningful rivals that can threaten the Empire has resulted in a chronic disease of complacency. The Empire was content with their Ravernal relics without any attempts to improve, its people prideful, and leadership conceited.

This mistake was paid very dearly when the unexpected appearance of two countries from different worlds, Japan from Earth and the Gra Valkas Empire from Yggdra, the resulting world war brought by one of the countries' ambitions, another war with what they thought to be a bunch of barbarians, and finally the fated showdown with the Ravernal Empire itself, the Holy Milishial Empire suffered setbacks one after another and found itself eclipsed by the two emerging countries' influence, forced to settle in the shade cast by the two countries.

But this is not the story of the Empire's decline, but the story of its road to prosperity, starting with the life of a certain future mage…

A house in Leiden, Holy Milishial Empire

Inside a house in a seaside town four hundred kilometers south of the Empire's capital, Runepolis, a silver-haired, blue-eyed young teenager has currently immersed himself in reading a thick book. Multiple papers scattered around him, containing notes, hand-drawn pictures, and sometimes mathematical formulas in a pile of an organized mess.

*Knock, knock, knock*

The boy shifted his gaze to the door of his room after the sound of knocking.

"It's not locked."

The door opened to reveal an older woman with physical features similar to the boy and carrying a cup of tea on a tray.

"Here, I made a tea for you."

"Uh? Did you make this for me? Sorry for bothering you, Mom."

The now identified mother of the boy smiled as she replied, "Don't worry about it. Besides, this is the weekend, why don't you go take a walk outside or something?"

"I was about to go outside anyway. Thanks for the tea, Mom." The boy smiled.

"You're welcome. Oh, and Meteos, before you go outside, clean your room first!" Meteos' mother called out before she went out of the room and closed the door.

The boy sighed and after some stretching, brought the tea cup to his mouth and savored the refreshing scent and taste of the tea. He then gazed outside the window of his room overlooking Leiden, contemplating his life so far.

"The gods really work in mysterious ways…"

Meteos Roguerider, a patriotic Holy Milishial Empire official, died of old age in the early 1700s, having witnessed the painful history of the decline of his homeland and the death of his friends in the wars that occurred during his lifetime. However, the next moment after he breathed his last breath, much to his shock, he awoke at the sight of his parents as a young boy on his fifth birthday. He then learned that somehow, he has been transported back in time to the year 1603 Central Calendar.

After the emergence of Japan and the Gra Valkas Empire in his previous life, Meteos began to diligently study their technologies and combined with his research on the Ravernal Empire relics during his time in that department with an overly long name, he has achieved a better understanding of a broad range of technologies, combined with his knowledge of magic.

With his memory from his previous life intact, Meteos vowed to use his knowledge of the future to change it. He wasted no time in creating plans for advanced machinery which, with his advance knowledge, is not a problem for him. This worried his parents who wondered why their only son started to spend hours cooped up in his room even during weekends, but he reassured them that he is alright. By the way, he also retains his knowledge of various magic spells although his low mana reserves as a child forced him to start training his body in order to use it properly, much to his annoyance. However, the problem is that Meteos lacked the resources and fund to enact his plan.

Sighing once more, he marked the page on the thick book he was just reading, stood up from his chair and began picking up the scattered papers, organized them, and placed them neatly on top of his desk. After that, Meteos changed into casual clothing and walked out of his house towards the nearby harbor.

His ancestors may have set the grounds for the Holy Milishial Empire to shine high in the sky, but he will make sure that it will shine victoriously.

Forever.
