Then.

Upon returning safely to Wang Du, Yudo decided to look around after everything that had happened at sea when he got home.

How come, all of a sudden, there was a huge tsunami?

I couldn't help but wonder when I was on the ground, but now I know it's clear.

I guess it's the result of the temporarily rising water level of Demon King Castle that emerged from the sea.

"... ok. What you see over there is definitely the legendary 'Castle of the Demon King Valhalla', which is said to have emerged in this world in the ancient days of Tai."

Sakura opened the book page with a castle with a lovely atmosphere.

The ink is sumptuous and I can only grasp a great deal of clutter, but when I'm told, I feel somewhat similar to what I saw at sea.

"Valhalla? What is that?

"There's no reason why you don't know. It's a fairy tale to tell this world."

Then Sakura gave me a detailed account of Valhalla, the Demon King's Castle.

Says.

Once upon a time in Tai Ancient times, the world was surrounded by 'great darkness', centered around Valhalla, the Castle of the Demon King.

It seems that humanity, living in the Dark Ages, had been ruled by the Dark Forces and had been spared a battered life.

It was Legendary Blood, a clan of brave men who stood up to break this situation, the representative of the Forces of Light.

The battle between light and darkness will last hundreds and thousands of years.

Eventually, thanks to the work of the brave, the darkness was clear and the world was to be engulfed in light.

In other words, it seems that the Demon King's Castle Valhalla symbolizes the full prosperity of this terrible dark age.

(... I guess it's my fault. Speaking of which, I think I've heard similar explanations lately)

At that time, what was past Yudo's brain was the numerous advice he had received from legendary hero, Ark Schwartz, during his previous visit to Numbers' Azit.

But.

Sometimes it doesn't fall to your heart.

According to Ark's story, by the time this world is consumed by darkness, there should still be fifty years of respite left.

Why is it now at this time that Demon King Castle is set to make a comeback?

For Yudo, who is out of specialty, it was something I don't understand.

"... Hello, you. You're not thinking about going to Demon King's Castle, are you?

"Yeah. Not at all."

Yudo immediately denies the question of Sakura.

What the hell is sad about and have to go ahead and visit dangerous places on their own?

Yudo originally did not want to take any action that was not in his interest.

"When you're so clearly denied, you're worried the other way around. It could be a global dilemma, right?

"That's it. This is it. I'm sorry, but there's something else I want to prioritize."

Yudo said with a crisp, crisp face.

(... well, they'll do something about it without me going out)

According to Yodo's standpoint, there were a few members of the Numbers who were strong enough to fight each other.

As for Isakoza, who holds the fate of the world, I want to pierce the stance of the other force present application whenever possible.

Such thoughts existed in Yudo.
