1 Chapter 0: (prologue)

*DUNNNNND* *DUNNNNND*

Running through the hallway of New Chaldea, situated inside the wandering sea. The last master of pan-human history, Ritsuka Fujimaru, is the one who saved humanity from being wiped from existence during the Grand Order and is now saving it once again.

together with him is his kohai, who has been with him since the Grand Order, cleared the Epic of Remnants, and is now uprooting the Trees of Emptiness, Mash Kyrilight, a Demi-Servant belonging to the Shielder Class.

When they arrived at the place, which seems to be the command center, a girl with short stature and a petite body greeted them with an enthusiastic smile, the one and only super genius Da Vinci.

"Hello, you two, and sorry for bothering you, right after finishing an event."

Ritsuka and Mash went upfront, then Da Vinci looked at Ritsuka, who was still tired after clearing many sections of an event for the lottery.

"I know you are still tired, but there's a new event in line for this month."

Ritsuka slapped his face twice so that he could shake off the tiredness.

"Well, as long as there are free summoning tickets and mats, I could farm all day!"

"Senpai, take it easy and skip this event! Or at least take a rest before going to this event, also where's Holmes-san?"

They looked around to see Sherlock Holmes not present in the command room, and then Da Vinci coughed and began explaining the situation.

"This event is in Asia South Korea, of 2015, also its more like a lostbelt than a singularity."

It surprised Mash since a brand new lostbelt appeared, well, a singularity that's more like a lostbelt.

Ritsuka began thinking they never had korean servants even though a well-known hero was there. Da Vinci then grinned as if she saw through Ritsuka.

"Since we don't know what's inside that lostbelt, I summoned us. A servant Ritsuka might Recognize."

A breeze blew through the room, accompanied by the scent of the sea, a man with a pointed beard and wearing a heavy canvas coat (Dujeong-gap) a double-edged sword (Geom) hanging from his waists, and a bow strapped to his back. While holding his helmet to his side.

"hehe, praise me the universal genius, for I have prepared for you the best servant when it comes to korea, the one who overturned a naval battle with only 13 ships against 333 japanese ships, in the battle of Myeongnyang. Admiral Yi Sun-Shin!"

"It is nice to meet you, the last master of pan-human history, as Da Vinci said, I'm admiral Yi Sun-Shin, a heroic spirit that hails from south korea, my class is that of the rider class."

"It's nice to meet you, admiral, I'm Ritsuka Fujimaru."

"nice to meet you as well admiral, I'm Mash Kyrielight."

Yi Sun-Shin just nodded his head then Da Vinci *coughed* to break the silence and then she said.

"Let's get inside the shadow border first. There, I'll explain the situation."

Meanwhile, in South Korea in the Kim Dokja's Industrial Complex.

The scenarios they encountered were harder than before as the difficulty spiked up. A man in an office looking into his phone with a face distressed more than before. The man's name is Kim Dokja.

"what the hell? it's not even here no scenarios were showing about this."

Kim Dokja turned off his phone and then looked at the blue screen that has been showing since an hour ago.

"Damn isn't the 'holy grail' with <eden>??"

A woman with bob-cut hair walked into the office as she cursed and clicked her tongue. She went in front of Kim Dokja and looked at him.

"By the looks on your face, this development wasn't even in the novels, is it?"

Kim Dokja could only nod as a scenario that has never happened before started happening.

"Han Sooyoung, please call for everyone."

"But how about that bastard?"

Kim Dokja stood up and looked outside the window. The sky looks weird as the clouds were now creating a circular formation.

"Don't worry about Yoo Jonghyk. We gotta solve this problem ourselves, even without the damn sunfish."

But of course, this was a lie. Kim Dokja would've wanted for Yoo Jonghyuk to be here as he was their strongest.
