The place that was put on the carriage and moved was a meadow with nothing that ran for about an hour after leaving the Imperial capital Luzenia.

The young grass stretching up to her ankle swells with a breeze.

The time is not too sunny because it is already past noon.

"I thought there was a duelling ground in the castle."

"Me and you will fight as hard as you can. It would be best where there's nothing, wouldn't it?

Kaisardo pulls out of the sheath, which would be made of iron, seeing from the gloss the giant sword that remains stabbed on the ground.

"Buster Sword."

"Do you want a weapon with that warped body and a wooden weapon?

The Japanese knife and the wooden knife.

"Hmmm......, the Gui Wood God Extinction uses the same incredible weapon"

"Mr. Kazt......, are you okay? Really? You don't need the power of a concubine?

"Oh, this is a battle between him and me - and..."

I haven't heard everything from Kaisard yet.

Tell me about my mother, and be firm with her.

That's probably...

"... ok. Because I'm trying to stay away..."

"- Well, are you ready?

"Kaisardo, would you like to make one bet before you fight?

"You say it's a bet?

"Oh, you seem absolutely confident in your power - but if I win, give me a hand"

"Hmm... if you lose to me, you can honestly promise to evacuate from Altras to Lugnica, the maritime nation, with the people of the Kaisel Empire."

"Fine."

I didn't expect you to accept this request, but this is good luck.

But even if I help you, I won't stop the attack from the moon.

"I know. - But what if I could defeat the Great Destroyer of the Deep Sea?

"At that time - let's stop the attack from the lunar plane. - But! It's too much for people to do."

While having a conversation, I put a Japanese sword in my right hand - and Kaisardo takes a distance with the buster sword.

- And...

- Well, let's get started.

"Oh......"

At the same time as we responded to Kaisard's voice, we both shrink our distance with one breath, and at the same time we wave our swords down from the upper section together.

Each other's selfishness bumps into each other - and at the same time the sparks scatter.

"Kazto, why don't you get serious?

"You're the one!

It commands mitochondria to live in cells in the body while distancing themselves from Kaizardo, to absorb the magic elements in the atmosphere, convert them into enormous amounts of energy and use them as biocurrents.

Furthermore, when they are poured into the Japanese knife, the Japanese knife is accompanied by magic letters floating, while amplifying the biological current, using amplified biological currents to enhance the optic nerve -, the cells - and looking at Kaisardo.

"That's -, Gui Wood God Extinction: Is it the God of Disease Thunder? that we can gain dozens of times more power than ordinary people."

"Yes."

"I see... Then I'm going to get serious too!

Things like white vapor rise from Kaisardo's body -.

"Then, once now! Let me show you too! [Divine Sacred Sword Fafnir] Appear!

At the same time as that word, the vapors that had risen from Kaisard's body until earlier - and the magic of the surrounding atmosphere - the composition of the world makes a sound in an instant and splashes.

- And as it becomes light and concentrates on the buster sword that Kaisardo is holding, it degenerates into a golden color that is just dazzling - and turns into a double-edged sword that exceeds two meters.

"- Now, between those who fought each other once. Shall I show you your power?"

"Fine."

In response, I kick the ground and approach Kaisardo as I circulate into my body with a biological current.
