A Legendary Kingdom, A Chance Encounter

"Birka?"

Yamato tilted his head. "Never heard of it."

That's not surprising at all; it would be strange if she knew, given her level of ignorance.

"That's not surprising."

Dr. Tsukimi nodded. "That country is indeed—"

"I know."

Sirius said.

Dr. Tsukimi looked up at Sirius with surprise.

"Huh?" Yamato even more astonished, blinking his eyes. "You know Sirius?"

"Kindness,"

Sirius nodded slightly. "On the Grand Line, above the Accumulated Emperor Cloud floating ten thousand meters above the sea, above that white ocean known as the White White Sea, there is a country called Birka."

The name Birka sounded familiar to Sirius.

Then, after a moment's thought, I remembered its origin.

Isn't that Enel's hometown? Come to think of it, it was destroyed by Enel this year.

"Ten thousand meters above the sea? White White Sea?"

Yamato paused for a moment, then exclaimed, "Isn't that Sky Island? The place Roger and Oden went to? Wasn't Sky Island originally called Sky Island?"

"Fool,"

Sirius tapped her forehead. "There's more than one Sky Island. The one the Doctor mentioned earlier, Visharia, is one of Sky Island."

"Furthermore, the Sky Island that Roger and his crew landed on wasn't actually called Sky Island."

Angel Island and God Island together are referred to as the God's Kingdom by the Skypieans.

"Is that so?"

Yamato, seemingly understanding but not quite.

"Oh! Sirius knows about it?"

Dr. Tsukimi called out Sirius's name.

Sirius didn't pay any attention; Yamato, that idiot, had been calling his name the whole time.

"Birka is indeed a country located on the White White Sea," Dr. Tsukimi said, "But not entirely."

"Ah?"

Sirius was somewhat bewildered.

What's the meaning?

"Birka is indeed located in the White White Sea now, but it wasn't in the past."

"Huh?"

Yamato's eyes widened. "Did they move up to the sky later?"

"It was indeed moved there, but not upstairs, it was moved downstairs," Dr. Tsukimi said with a smile.

"..."

Sirius slightly taken aback.

Speaking of which, isn't that city on the moon also called something like "Ka"?

Birka?

Birka?

"Move down? From where? Is there a higher place?" Yamato was confused.

"Birka, the inhabitants of that country, come from there."

The old man raised his right hand and pointed to the sky.

Yamato turned around and saw something in the direction the old man was pointing.

"Eh--!!!!!"

Yamato almost stood up. He looked at the old man, rubbed his eyes, looked back at the sky, then back at the old man again. "You mean, the moon?"

"They came from the moon!?"

"Wow, that's amazing, isn't it?"

The old man smiled mischievously.

No wonder Enel was determined to go to the moon no matter what.

It turns out they wanted to return to their homeland.

"From the moon!"

Yamato's eyes were practically glowing. "Doctor, why did they come to the Blue Sea? How did they get Blue Sea? What does the moon look like?"

She was simply bursting with curiosity.

Those were migrants from beyond the world!

But Dr. Tsukimi flipped his hands, and the little bear shrugged, "I don't know."

"Huh? You don't know?" Yamato leaned against Sirius's back in disappointment, complaining resentfully, "How could this be!"

My interest was definitely at its peak then.

"I've never been to the moon either."

The doctor smiled and said, "I only heard them mention it when I went to Birka in the past. They said they came from the moon, and the technology they inherited also came from that planet. As for the rest, even they themselves have forgotten it. After all, that history is too long ago."

He sighed, "So long ago, everything has been buried in the dust of history."

"I see."

Yamato nodded, then excitedly hugged Sirius's neck, "Sirius! How about we go to Birka next? Let's uncover this secret!"

It's probably too late.

Enel has probably already completely destroyed his homeland and then strategically moved into the God's Domain.

Sirius knew about this, but Yamato didn't.

She asked excitedly, "Doctor, what kind of country is Birka? Is it as prosperous and developed as this place?"

"That's not it,"

The doctor shook his head, looking regretful. "The Birka have left behind many ancient technologies, but they can no longer understand them. Their basic education is too poor; they've completely regressed to the level of the tribal era."

"Moreover, even after I analyzed those techniques and wanted to teach them, they weren't interested. Now they value individual strength more."

That's a real shame.

Sirius also sighed with some emotion.

Compared to individual military force, it is clearly the power of technology that is more capable of driving productivity and promoting national and social development.

"However, there is one exception,"

The doctor added, "Hehehe, he said he wanted to return to the Endless Vearth where his ancestors lived, so I taught him some knowledge about building spaceships."

Sirius was genuinely taken aback.

You're not talking about Enel, are you?

But Sirius then realized something was wrong; the timing didn't match.

Tsukimi Island was already under construction and famous decades ago, and Enel is only thirty-one years old this year, the same age as Shanks.

That must be Enel's elder.

So, is it also a dream passed down through generations?

"A spaceship!?" Yamato noticed something else, and was incredibly excited. "Can it fly into the sky? Fly to the moon?"

"Hehehe, isn't that interesting?"

"That's fantastic!"

Yamato shook Sirius's neck. "Sirius! Let's go on an adventure to the moon!"

Landing on the moon?

That sounds good.

"So, we'll be staying here for now?"

Inside the Sirius, Jack raised an eyebrow as he watched Dr. Tsukimi jumping around like a monkey in the cabin.

"Kindness."

Sirius nodded and smiled, saying, "This time, maybe we'll have one more companion."

"Another partner?" Jack looked completely bewildered.

The Sirius Pirates temporarily staying on Tsukimi Island.

Since they couldn't stay on the ship every day, Sirius and Yamato went to play on the island every day.

Although I've already visited the most famous tourist attractions, the local customs and lifestyle on this island are also very interesting.

On this day, Sirius took Yamato into a coffee shop to spend afternoon tea.

As soon as he entered the restaurant, Sirius noticed a certain man.

The guy was fast asleep, basking in the sunlight, sitting by the window.

"That guy!"

Yamato noticed it too, and she tugged at Sirius's sleeve.

That's quite unusual.

"Ignore him."

Sirius calmly led Yamato sit down.

That guy has a strong aura, no less than Yamato's.

He's definitely no ordinary guy; this sea is truly a place where hidden talents abound.

But it's none of my business.

Order something, eat something.

Just as they were leisurely enjoying their lazy time, the coffee shop door opened again, and a man hurriedly walked to the side of the guy who was fast asleep.

"Hmm--"

The man woke up at just the right moment.

Sirius glanced at him out of the corner of his eye; he was a rather young man, and quite good-looking.

He stretched and yawned. "And then?"

"Still not here," the man who arrived later said respectfully.

"I see. Then there's nothing we can do."

The young man stood up, yawning. "Let's go back."

"Yes."

The two left the coffee shop one after the other.

So, what exactly do they do?
