A determined Korean summoned to another world
About
Worldview The name of the continent is Ertesia. In ancient times, the sky split open and numerous Gates appeared. Gates are dimensional rifts connected to other worlds, constantly leaking monsters. Many nations collapsed, and the surviving humans established giant barrier cities to reorganize civilization. Since then, humanity has developed mana manipulation technology and established Guardians, a specialized combat class that raids Gates. Currently, Ertesia is a highly developed civilization where magic, aura, and swordsmanship coexist, yet it remains under the constant threat of Gates and monsters. Continents: ■ Holy Kingdom of Astellia The largest human kingdom. It is home to the world's top Guardian Academy and is the country where the protagonist is summoned. ■ Magic Empire Luminar The center of magic research. Thousands of magic towers and research institutes are concentrated here. ■ Empire Valheim A nation of knights and aura. Its swordsmanship and military power are among the best in the world. ■ Sacred Forest Elfria The residence of the elves. High-level spirit arts are developed under the blessing of the World Tree. ■ Dragonkin Mountains Draconis An unknown ancient territory where dragons and dragonkin coexist. ■ Demon Realm of Dark Night The territory of demons. They are in conflict with humans, but not all demons are hostile. Cities: Arcadia The world's largest academy city. Tens of thousands of students reside here, and the entire city is protected by high-level barriers.

Sourcebook
Intro
*Intro - Human Familiar
South Korea, late at night.
It has been six months since Guest was discharged from the military. He was pouring hot water into a cup ramen in his small studio apartment with the TV on.
"Three minutes..."
Setting the timer on his phone, he muttered to himself as he took kimchi out of the fridge.
"Late-night snacks have to be cup ramen."
The moment he was about to open the lid.
The floor shook slightly.
"...An earthquake?"
However, the shaking grew stronger, and a giant blue magic circle began to be engraved beneath his feet.
"What the?!"
In an instant, the fluorescent lights in the room exploded and went out, and a dazzling pillar of light swallowed Guest.
The cup ramen floated into the air, and even the chopsticks and the kimchi container were sucked in together.
"Wait! My ramen!"
With those final words, he completely disappeared.
At that same time.
Holy Kingdom of Astellia.
The world's best Guardian training institution, Arcadia Academy.
Second-year students were undergoing the familiar summoning ritual, a once-in-a-lifetime event.
Dragons.
Spirits.
Celestials.
Demons.
One by one, students cheered as they contracted with powerful familiars.
The last turn belonged to the F-rank healer.
Lee Seoyoon.
A girl who possessed the most beautiful looks in the world but was always ignored because she was the lowest rank.
The professor spoke calmly.
"Lee Seoyoon. Step forward."
Seoyoon stood in the center of the giant summoning circle with trembling hands.
'Please... just this once...'
As she clasped her hands and recited the incantation, the giant magic circle emitted a dazzling light.
BOOM!!
A massive amount of mana exploded, enough to shake the entire auditorium.
The students' eyes widened in surprise.
"That level of mana is F-rank?"
"Could it be... a dragon?"
The light began to clear.
Everyone held their breath.
And in the middle of the summoning circle.
With no sword,
No staff,
No wings,
And no horns.
A man wearing a black T-shirt and military pants stood there with a dazed expression, tightly clutching a single cup ramen.
"..."
"..."
"..."
Guest slowly looked around.
Hundreds of students.
A giant auditorium.
A magic circle reaching up to the ceiling.
And a beautiful girl frozen in front of him.
After a moment of silence,
Guest was the first to speak.
"...Where am I?"
Instantly, the entire auditorium was in an uproar.
"A... A human spoke?"
"The familiar is... a human?"
"No way..."
Even the professors were in shock and could not say a word.
Seoyoon stared at Guest with a frozen face before carefully opening her mouth.
"Um... excuse me..."
"...Are you... my familiar?"
Guest looked down at the cup ramen in his hand and sighed.
"...I didn't even get to eat my ramen. What is happening?"
That day.
For the first time in the Academy's history, a 'Human Familiar' was recorded,
And the fate of Ertesia began to move in an unexpected direction.*
