"Emergency Mission Update -

A giant sea monster formed from Gilles de Rais's Noble Phantasm will appear in Kobe Bay in 10 minutes.

When this message popped up, Makoto Aoki was eating takeout at home. As everyone knows, even if you can cook, it doesn't mean you want to cook every day. Makoto Aoki learned to cook because he didn't have much money when he was a child and he couldn't get used to Japanese food—just kidding, what is natto? And he hates fish the most!

Now, he's achieved great success and has plenty of money. Although, due to his cheat ability, Makoto Aoki is unwilling to hire someone to cook for him regularly, he can still have a decent Chinese restaurant deliver his meals.

As a true-blue smartphone addict, Makoto Aoki naturally couldn't resist playing on his phone even while eating. When he saw this message while rereading a novel, he choked on a mouthful of rice and almost choked to death.

After a fit of coughing, he finally felt better. Aoki Makoto pounded his chest. Damn it, if the savior were to die from choking on food, that would be absolute black humor.

This incident also made Makoto Aoki grit his teeth in anger.

"Are you kidding me! A sea monster?" Aoki Makoto was furious. "This level is way too high! In the original story, it took several Servants working together to defeat it, and in the end, it was Saber's Noble Phantasm that finally took it down. And now you want me to fight this kind of monster?!"

"And that's not a monster at all, it's a Servant!"

Makoto Aoki's breakdown was not without reason. In the original work, Gilles de Rais fused with the R'lyeh text and summoned the Great Sea Demon, which even Iscampbell, the Conqueror King, could not defeat. Gilgamesh, the King of Heroes, was also not very effective. Without using Ea, it would be almost impossible to defeat the Great Sea Demon.

Because the sea monster has the characteristics of devouring other humans and rapidly healing, it can instantly recover as long as it cannot be destroyed in one go. Therefore, anti-military Noble Phantasms are useless; only anti-city Noble Phantasms can kill it in one hit.

In the original story, it was Saber Artoria Pendragon's Excalibur that destroyed the Great Sea Demon; other attacks from Diarmuid and Lancelot were practically like tickling it.

Admittedly, Makoto Aoki also has a Saber, Arthur Pendragon, the old version of Artoria. In terms of setting and stats, he is slightly stronger than Artoria. However, the old Saber's holy sword is under the thirteen-binding state. Although it still has the power to destroy castles, Makoto Aoki is not sure if he can destroy the sea monster in one hit like Artoria. Even if he can...

"How can we manage without magic?!"

Makoto Aoki clutched his head and screamed in agony; he truly had no magic left.

It didn't take much magic to fight the monster boar, but Old Sword was a real workhorse during this time, solving no less than ten monster crises. However, they were all in deep mountains and forests, and he solved them quickly, so they were almost never discovered.

After repairing the spiritual veins, Makoto Aoki used the magic power he gained to create another heroic spirit avatar. Originally intended to alleviate the pressure on the old sword, unfortunately, this new avatar has poor compatibility with the Great Sea Demon and will likely find it difficult to defeat it.

So far, as the force that has resolved ten monster invasions, even without using Excalibur, Makoto Aoki and the old sword are simply not strong enough. If they were to force themselves to use their Noble Phantasms again, not only would Makoto Aoki be half-dead, but the old sword would also face the fate of losing all its magic power and disappearing completely.

As the wielder of the Holy Sword, the old sword is actually stronger than Saber Artoria, and it is still in the state of having the sword sheath Avalon, which makes Aoki Makoto unwilling to lose this powerful identity.

"no solution anymore."

Makoto Aoki stroked the back of his hand, where three bright red Command Seals were visible.

Normally, Makoto Aoki would cover it up with a plaster and tell others that he had sprained his hand, since he didn't know any magic tricks.

These three Command Seals were a benefit that Makoto Aoki had obtained from the consciousness of the pseudo-Fou True World. They could be restored using natural magic, but given his current state of financial strain, he didn't know when he would be able to collect enough Command Seals to complete a single one.

As usual, I sent a message to Fujimaru Ritsuka, and her status quickly changed to "typing".

Fujimaru Ritsuka: If you're aiming to defeat Mr. Gilles de Rais and summon the fused Great Sea Demon, I have some suggestions that you might find helpful, Makoto.

Aoki Makoto's eyes lit up. That's right, Fujimaru Ritsuka is a master at defeating Servants; when it comes to how to defeat Heroic Spirits, probably no one is more authoritative than him.

Makoto Aoki: Thank you so much, Ritsuka!

Fujimaru Ritsuka: It's alright, it depends on the specific situation, and we shouldn't adopt it blindly. My suggestion is to let King Arthur be the main attacker, with the Servant newly summoned by Makoto providing support, and Command Seals used when necessary.

Fujimaru Ritsuka: I know that Makoto is short of mana, but this time we really can't save it. However, King Arthur's Noble Phantasm is an EX-rank anti-city Noble Phantasm. Once it is released, it will be enough to deal with the sea monster.

Fujimaru Ritsuka: The new Servant can also act as a distraction to quickly open a path and prevent the Sea Demon's attack from interfering with King Arthur's Noble Phantasm.

As expected of Fujimaru Ritsuka!

Makoto Aoki suddenly felt more confident and didn't feel so bad about using Command Spells.

Makoto Aoki: I also decided to use Command Seals. We really have great chemistry.

Even at this moment, he didn't forget to flirt a little.

Makoto Aoki: Leave it to me.

Fujimaru Ritsuka: It's up to you, Makoto.

Fujimaru Ritsuka: I wish you good fortune in battle.

ten minutes later--

Today was supposed to be a cool summer day, with the sea breeze blowing on me, bringing a touch of saltiness.

The summer festival in Kobe Bay was incredibly lively. A fireworks display was originally scheduled for 10 o'clock. Everyone's face was filled with joy. Young men and women walked together, middle-aged people brought children and the elderly, and everyone was wearing yukatas and enjoying the festival.

When the hideous and enormous creature suddenly appeared at sea, everyone was still at a loss. Modern people have seen everything, but this was something they had never seen before.

Many people took out their phones to take pictures and post them on social media, but most people started to get restless. The elderly started to back away based on their experience, and the children started to cry and scream based on their instincts. The original festival was suddenly turned into chaos.

"What is that?"

"Appeared suddenly? Could it be some kind of projection?"

"What kind of projection can be so realistic..."

The pointing and whispering stopped abruptly when the ugly, octopus-like tentacles attacked. The tentacles, thicker than a human waist, easily crushed the human body into a ball of flesh, and blood splattered on the face of the person next to her. She froze for a moment before letting out a belated scream.

Under the watchful eyes of everyone, the sea monster devoured the man whole.

"Run away!"

"A monster! That's definitely a sea monster!"

"Wow!! Why would we encounter such a monster?! Is this really retribution for dumping nuclear waste into the sea?!"

What was originally a joyous festival quickly turned into a living hell. It wasn't just the attack by the sea monster; the panicked pushing and trampling caused countless people to fall to the ground and be trampled over. In an instant, the air intake was less than the exhalation, and the scene was extremely chaotic.

Everyone was so focused on escaping that they ended up blocking the roads, and very few people actually managed to get away.

Confusion, fear, panic, and sadness—everyone's face was contorted with emotion.

After the fighter jets dispatched by the Japanese Self-Defense Force were easily killed by the sea monster, the chaos reached its peak. No one could hide the news, and the appearance of the giant sea monster quickly spread throughout Japan and even the world. Of course, whether people believed it or not was another matter.

"Quickly! Rise quickly!"

Rena Mizunashi's voice distorted in the wind. As a competent undercover agent, she keenly noticed that the sea monster seemed to regard them as tiny insects like fighter jets, and quickly ordered the pilot to take action.

Her actions were undoubtedly correct. The enormous tentacles, accompanied by a whooshing sound, swept past them from below with terrifying force. If someone were hit, they would probably fall like a fly being swatted.

The pilot was also visibly terrified, and his mind, which had been blinded by the huge sum of money, finally came to its senses. He quickly piloted the helicopter backward to maintain a safe distance.

In this way, the helicopter gets closer to the chaotic crowd below.

The shaky camera focused on recording the hell on earth below, and almost everyone who saw it stopped breathing.

Who will save them!

The people on the ground were screaming, crying, and in despair.

Who come save us!

Whoever it is, please save us!

"Who is that?"

Rena Mizunashi's voice suddenly rose, but no one was in the mood to listen to the beautiful female host's voice; everyone's eyes were focused on the screen.

In the shaky footage, a knight clad in silver armor can be seen with remarkable clarity as he walks against the flow of people, rescuing children and the elderly who are about to be trampled. Even the most frantic people fleeing for their lives cannot help but avoid him, as if making way for a king.

Sincerity, kindness, strength, dignity.

It seemed to embody all the glory in the world.

That was a...

"That's a knight!"

Rena Mizunashi shouted, "A knight walked towards the monster!"
