The world of Type-Moon starts with saving Altria!

And this question was soon answered.

"I am Keto, their mother, and mistress of the Oceanus."

"This……"

Hearing this name, Ian immediately realized that his premonition had come true.

This is Medusa and their mother!

Ian struggled to salute her, but found that he had lost the strength to do so.

This is the deep sea.

The water temperature is nowhere near as warm as the surface.

The man's body temperature had long been completely taken away by this terrible environment. Only the last bit of willpower was left, which could barely maintain his desire to communicate with Keto.

Fortunately-

Engraving does not pay any attention to these meaningless etiquette.

She spoke gently:

"It's okay. In your current state, it's understandable that you don't salute me."

"I... am not angry."

"Besides -"

"You became what you are now because of my daughters. It is neither reasonable nor moral for me to be too harsh on you."

"Thank you for your understanding." Ian responded to the hostess of Oceanus.

"But Lord Keto, can you answer a question for me?"

"what is the problem?"

"that is……"

Ian raised his head with all his strength and looked above himself.

Being in the deep sea, he could only see a glimmer of light on the surface of the sea.

But even in such a deep environment, the man could still feel the breath emanating from Poseidon - He, who did not get Medusa as a "sacrifice", was extremely angry at the moment.

At His call, waves of wind and wind arose from the sea and then continued to surge in all directions.

The destructive power of this scene was so strong that even the deep sea was disturbed.

"How...can I try again for your daughters?"

Even though his body had already reached its limit and his consciousness was only on its last breath.

But for Ian, even if there is a tiny chance, he still wants to try.

This is not a gambler's mentality.

It was something he had agreed with Medusa before setting off.

"This time, I will definitely solve all the problems!"

and so--

Even if there was only a glimmer of hope, Ian knew he had to do his best.

Faced with the man's doubts, the three sisters' mother, Keto, did not respond immediately, but asked another question instead.

I saw the light coming from the deep sea, symbolizing her, beginning to project towards the sea surface, illuminating the dark environment a little.

"Pegasus."

"Do you really think that just killing those people can completely eliminate the threat from Poseidon?"

"this?"

To be honest, Ian did have such an idea.

After all, if these people who have long been planning to use Medusa in exchange for peace disappeared overnight, then the three sisters would no longer have any so-called weaknesses, right?

With their abilities, they can definitely find a new place and continue living like this.

however--

It was like she had sensed the man's true thoughts.

Keto once again echoes this thought:

"What you are thinking is indeed a possible situation."

"but--"

"Poseidon is more likely to continue chasing my daughters than to let them go."

"No matter where they go, He will still not turn against them."

"Pegasus, the real solution to the problem is not to let them escape, but to find a way to get rid of Poseidon. Do you understand what I mean?"

"..."

[You fell into silence.]

[Of course you know that destroying Poseidon is the best way in theory. ]

[But the key to the problem is——]

【Who can do this? 】

[You should know that even as powerful as Stheno and Euryale, their combined attack did not cause any actual damage to Poseidon. ]

[This huge machine that fell from the sky is an enemy that is impossible to defeat in this era. ]

【unless--】

【The Keto in front of us has mastered a method to deal with Him. 】

"Master Keto."

"Excuse my stupidity, please be more straightforward."

Ian responded very sincerely.

"I... really can't think of a way to defeat Poseidon."

"..."

The light symbolizing Keto was silent for a moment, and then responded once again.

"Pegasus, I believe you have witnessed the scene of Poseidon's fall?"

"This……"

Listening to Keto's words, Ian's thoughts gradually drifted back to the moment when Poseidon descended from the sky.

At that time, He had not yet become as arrogant and violent as He is now.

The overall threat level will be much smaller than it is now.

"Yes, I witnessed that day with Medusa."

"It would be nice if... we could do something in advance at that time."

"That's not your problem." Keto comforted Ian.

"In fact, there is nothing you can do."

"These machines do not belong to our era, so naturally we cannot use the knowledge of this era to fight against them."

"..."

Even though he had realized this a long time ago, Ian still felt a little disappointed when he heard Keto confirm it.

Something otherworldly from above the sky.

Naturally, it is impossible for people of this era to eliminate it.

but--

Ian also noticed something that excited him.

There was still a glimmer of hope in Keto's tone.

"If that's the case—"

"Master Ketuo, since you chose to come to me... then there should be a way to solve the problem, right?"

"..."

There was another long silence.

Finally, Keto seemed to have made up his mind and focused the light representing himself on Ian.

"Pegasus, I sense your determination."

"So--"

"Let me tell you all these memories that should have been hidden forever."

As soon as Keto finished speaking, Ian felt many memories from the past flooding into his mind.

That is the past of the Oceanus Sea, and also the efforts of Keto.

It was a great deed that no one knew about.

【This happened in the past.】

[The fall of a giant machine is not the only one.]

[As the master of the Oceanus Sea, Keto has witnessed such things several times.]

[In the past thousand years, several huge machines like Poseidon have fallen into this vast sea. ]

[Almost without exception, they all had shocking lightning scars on their bodies, as if someone had launched a powerful attack on them. ]

[Athena, Apollo... names that seemed like gods fell into Oceanus one after another.]

[As the hostess here, Keto had already noticed the abnormality of these uninvited guests. ]

【so--】

[From the moment they fell into the Oceanus Sea, the sea mother used all the means she could to forcibly cut off the operation of their bodies.]

[Of course, this is not without cost. ]

[Just like Poseidon, each of these machines from the sky has performance that surpasses this era. ]

[As a native Greek goddess, Keto is quite difficult to handle. 】

[Luckily——]

[Those lightning traces still had a significant impact on the operation of these huge machines. ]

[In the end, Keto paid the price of his own body dissipating in exchange for the long-term dormancy of these machines.]

[This is also the reason why Poseidon failed to detect her - how could a long-dead sea mother be detected with signs of life? ]

[Although he was not detected, Keto still could not change the special nature of Poseidon. ]

[His body was indeed severely damaged by lightning, but most of its systems did not become inoperable. ]

[It was as if the initiator of the attack had deliberately avoided it.]

[So even if she is as powerful as Keto, she has already exhausted all her means at this moment, and can only watch this uninvited guest from outer space do whatever he wants on her sea.]

"This……"

After learning the truth about the past, Ian felt his breathing become much faster.

after all--

According to Keto, there are now several machines similar to or different from Poseidon sleeping in this ocean!

"Master Keto... you are burdened with a lot of things."

"It's not much of a burden."

A light flashed from the deep sea, and it was a voice full of responsibility.

"This is what I should do."
