I came to visit the city of the Sirens.

The next morning.

I came outside the city with Triton, the sea god.

"So, what do you want from me? What am I supposed to do?"

Triton points to [it] on the ocean floor.

"The ...... temple on the ocean floor? Ruins or something?"

There, looking up, was a structure made of stone.

Even larger than the giant Triton.

Moss was growing here and there, reminding us of its age.

"No, those are not ruins. It is an ancient weapon.

"Heh. Ancient weapon. This?"

"Yes. It's called Vestia, and it's a huge weapon.

"Vestia...... hmmm. Is this a sea turtle?

That's right. This is [Keronioidea] ...... one of the ancient biological weapons that inhabit this world."

"Why do you have this thing ......?" 

Triton explains with a grim expression.

"It was created by Sally the Wise in order to prevent chaos in the world after the death of the god of valor.

Sally is one of the teachers of Eugene the Brave.

"So this is one of the magical tools she made. But why are you in trouble?

"It was a weapon that was created to prevent evil such as the Demon King from ever running rampant again, but one day it went out of control."

"Runaway? Why?"

It has been 2000 years, and we still don't know what happened. We, the Six Guardian Gods, were dispatched to stop the six ancient beasts (Vestia) that had run amok.

So the Six Guardian Gods weren't there from the beginning.

But from the looks of it, this ancient beast isn't moving. So it doesn't matter, does it?"

"...... No. According to the guards' reports, the site has been slowly resuming activity for the past three months."

But it soon stops moving.

The seal is about to be broken. If it is resurrected, it will use this weapon run amok to eradicate the people who live in the sea.

I know what's going on. What should I do?

"We need to get inside the ancient beast's body and access the control unit at ......."

And that's when it happened.

Goggoth......!

"It's moving! Oh, no! I thought you didn't break the seal!"

Gradually, the ruins rise up from beneath the sand.

A gigantic ancient weapon in the shape of a sea turtle is revealed.

[The sea turtle is in the shape of a sea turtle. GYOOOOOOOOOO !!!!!]

A huge cry that shakes this whole ocean.

With a cloud of dust, the sea beast is activated.

"Julius! There is not a moment to lose in this situation! Get inside the body as soon as possible and check the control unit at ......."

"Oh, I know."

In my right hand, I make the magic sword Venomzard appear.

"I just have to destroy it, right?"

"Ha! Hey! What nonsense! There is no way you can break such a huge thing!

[Laughs. GYAOOOOOOOOOOOO! ]

A Kaiju is rushing toward me.

It's going pretty fast, even in the middle of the sea.

"No! Sir Julius! That was a close one!

The huge body of the enemy was about to kill me when...

Pitter patter......!

I was catching the tip of the Kaiju's nose with one hand.

"What! I never thought I could catch this huge body so easily!"

"Good boy."

Grabbing the tip of his nose, I throw him toward the seafloor.

Zdooooooooooooooooooo............!

With a dull thud, the Kaiju falls to the seafloor.

[Sound GYAOOOOOOOOOO! !

Numerous holes are made in the carapace of the Kaiju.

Countless missiles were launched from the holes.

"How many? Sir Julius! Evacuate!"

Missiles rain down on me from all directions, and I don't move an inch.

I swing the magic sword in my right hand lightly.

Parryiiiiiiiiiiiiiiiiin!

The missiles are all bounced off by the attack reflex (parry) and fly to the Kaiju.

Boom, boom, boom, boom, boom, boom!

Explosions occur all over the Kaiju's body.

But from the looks of it, there seems to be no damage.

"That's what I expected from a turtle. It's pretty sturdy, isn't it?

"The carapace of the sea animal Keronioidea is said to be the hardest in the world. It is written in a document left by Master Sally that no one can harm its shell.

The sea beast stretches its neck and opens its mouth wide.

It seems to be swallowing water.

The water is being sucked into his mouth violently.

Triton, who is at a distance, is about to be sucked in.

But he manages to hold on by thrusting the harpoon in his hand deep into the water.

"This is an opportunity! Mister Julius, you've got to get inside his body and ...... the control unit, Mister Julius!"

I didn't move an inch from where I was.

"Are you crazy? Why are you so unconcerned in this torrent of water?

"Well, I'm just holding on, aren't I?"

"Oh no! How could you do that in water with no foothold!"

"I'm just using wind magic to create an air foothold and stand on it. ...... What's so surprising about all this?"

Triton looks up at me, aghast.

"My God,...... it's too out of the ordinary,...... to create enough air for a foothold in deep water where oxygen is completely non-existent!"

"It's time to get this over with."

I swing the magic sword in my hand.

"Sir Julius! That's absurd! The opponent's shell is an absolutely unbreakable defense ......."

"Hit!"

Swing the sword at an angle.

Zbaaaaaaaaaaaaaaaaaaaaan!

The slash runs through the water, cutting the shell of the beast in two.

The enemy's body is cut in half and it stops moving.

"............"

Triton, with a soul-sucking look on his face, falls on his buttocks.

"Is this okay?"

"Yes, that was ...... what the hell ......?"

"What, I just swung my sword?"

"No, no, no, no! It's not right that just swinging a sword could obliterate that huge body!"

That's when it happened.

Ha-ha-ha! Well done, you have defeated this ancient weapon! But! I, who was possessed by the control unit of the main body

"Tei."

Zbaaaaaaaaaaaaan!

I swing my sword as I did before.

The Kaiju's carapace and some kind of black blur were all obliterated.

"See, you could have done it just by swinging the sword!"

"No! Well, ...... eh! No, no, no! Now! Wasn't there something there! There was some kind of mastermind behind it!"

"What, there's such a thing?"

The Kaiju, with a shocked look on its face, has left no trace of its former self.

Then it looks at me.

"Brilliant! Lord Eugene, God of Valor!"

Triton, in tears of joy, grabs my arm.

"Thank you! Thank you! You are the true messiah who has come down to earth after 2000 years!"
