It turns out that my youth story is fgo!

The battle between Taigong Wang and Joan of Arc seemed to have reached a stalemate. Joan of Arc could not do anything to Taigong Wang, and Taigong Wang could not kill Joan of Arc quickly. But is it really so? Unconsciously, Joan of Arc was led away from the previous road, and here was already a forest. Taigong Wang waved the red long whip, and the elongated whip body blocked the surroundings into a cage, making Joan of Arc unable to move for a while. "I'm sorry, Miss Joan of Arc." Taigong Wang opened his eyes, his eyes sharp, "Why do you think I used magic to guide you here?" Joan of Arc's purple pupils shrank, it's bad! The smell of gunpowder slowly spread between the wings of her nose. Unfortunately, for an antique from hundreds of years ago and a rural girl like Leticia who was not very knowledgeable, Jeanne could not recognize the danger at the first time.

Makoto Aoki pressed the button in the dark.

"Booom——" The white light of the explosion drowned everything around, and the huge sound was a step slower.

Tai Gongwang did not relax his vigilance. He and Makoto Aoki knew that this attack could not defeat Jeanne d'Arc. After all, she was a heroic spirit with EX magic. The so-called treasure "My Lord is Here" was just a conversion of her EX magic.

It can be said that even if Jeanne d'Arc took King Arthur's light cannon, as long as she did not open more than half of the seal, she might not die.

But EX magic cannot resist physical damage, that is, if the holy sword penetrated Jeanne d'Arc's spirit core, she would die.

So, Makoto Aoki cheated.

He used a bomb.

That's right, ordinary bombs can't hurt Jeanne, but it may not be the case after Tai Gongwang's enchantment. It's more of a physical attack than a magic attack, not to mention that Jeanne can't be spiritual.

She appeared in the body of the rural girl Leticia, which also made her unable to be spiritual, and even needed to sleep and eat.

In other words, even if Jeanne couldn't be killed in one blow, she would still be affected by the bomb.

That's enough.

The smoke and dust stirred up by the explosion dissipated, and a figure could be seen standing there. As Aoki Makoto expected, it was almost impossible to kill Jeanne with a mere explosion.

"——My Lord is here!"

She even unfolded her treasure to defend against Tai Gongwang's attack. After all, the effect of the magic can be defended by the treasure.

But Jeanne's current vigilance was all on Taigong Wang, who had not yet taken advantage of the victory to pursue, and she was completely unaware of her surroundings. After all, as a ruler, she could even see through Assassin's hidden breath, and could be said to be the type of servant who was least afraid of sneak attacks.

But Jeanne didn't notice that a small communicator fell beside her along with the surrounding rubble, because she really didn't recognize it, and this communicator didn't have any magic fluctuations.

This was the fatal point.

So when Jeanne was at her lowest level of vigilance during the protection of the Noble Phantasm, the secret raid began.

"I caught you♡~"

Aoki Makoto's real trump card, the manager of the Moon Holy Grail War, the top AI, BB appeared.

...

BB, once a superior AI configured to manage the health of the Master in Mooncell Automaton, went out of control due to a bug and became Cancer that invaded the computer world. It was also the computer demon that dominated the back of the moon and hindered the SE.RA.PH Holy Grail War.

In the conventional line, the final BOSS is almost always this purple-haired girl of the cherry tree, and as an AI, she naturally has advantages that other heroes do not have.

She can transfer in any electronic device, because the essence of BB is the spiritual data in the Mooncell Automaton.

This is also the biggest reason why Jeanne, who has the ability to search for enemies in a wide area, did not find BB. Before emerging from the electronic device, BB did not even have a spiritual reaction.

"BB-Channel~" Without any hesitation, BB directly unfolded the treasure, and the unknown cherry pink around suddenly locked Jeanne.

"This is not okay, but please rest assured."

Saying this, BB suddenly transformed, and the black cloak on her body turned into a white nurse uniform, revealing her beautiful figure.

"Leave it to me, BB!" She raised a huge syringe, the colorful medicine inside was quite suspicious, and then stabbed the needle into Jeanne's heart and pushed the medicine in.

"Hey~ How was the injection this time~"

After retrieving the syringe, BB will

The power she absorbed was distributed to the people around her, and Tai Gongwang could feel her magic.

"What on earth is this..." Jeanne covered her chest in pain and half-knelt on the ground. Even so, she did not lose consciousness immediately.

"Moon Cancer? Special job? Why did it appear?" Jeanne was puzzled.

"Hehe, this is exclusive to BB. Although other people have joined later, BB is the master of playing with the rules." BB's purple eyes were scarlet, "So old woman who maintains the rules, just let BB play with you obediently."

Jeanne wanted to say something, but the unknown drug injected by BB just now directly blocked her consciousness. The blonde girl's eyes became dull and no longer moved. .

"That's it, be my toy." BB was extremely proud.

"Don't waste time, hurry up and find a way to master the Holy Grail through Jeanne!"

Aoki Makoto walked out of his hiding place and told his real purpose.

If we were to ask which Heroic Spirit knows the Holy Grail best, apart from the Heavenly Grail like Irisviel, it would be BB. As the manager of the Moon Holy Grail War, she once held the "Golden Grail" and played around with the Holy Grail War. As a servant who breaks the rules and is essentially a "BUG", she is the natural enemy of the Ruler.

So it's enough to just look at the restraint of FGO. As a Moon Cancer, BB is not actually restrained by the Ruler Jeanne.

"I'm really anxious, senior." BB smiled maliciously, "Just the rules of the Holy Grail War, just think of it as BB completely distorting it."

"It should be okay," Aoki Makoto was a little worried, "Through Jeanne's channel to return to the Holy Grail, let BB follow you back to the Greater Holy Grail. If you're lucky, you should be able to completely master the Greater Holy Grail."

In the Holy Grail War, the Holy Grail is actually the key to everything, just like Amakusa Shiro Tokisada decisively attacked the Greater Holy Grail. With the Greater Holy Grail, you almost have endless magic power.

This was the inspiration given to Makoto Aoki by the Third Holy Grail War. At the beginning, it was because Angora Mainyu returned to the Holy Grail that he completely distorted the inside of the Greater Holy Grail, turning it into a piece of black mud.

If BB goes in, it should be possible to completely use the rules of the Greater Holy Grail, and even control part of it, and even replace Jeanne as the ruler.

Anyway, BB has actually been a referee of the Holy Grail War, but not this session.

At that time, the referee will stand on Makoto Aoki's side, how can others win?

Of course, if Amakusa Shiro and Tokisada get the Greater Holy Grail with great difficulty, but find that it is not the Holy Maiden of Winter, but the devil BB, then it will be a lot of fun.

"By the way."

Even if it is Makoto Aoki's vest, he is not at ease with BB, and then he asks: "Don't change the nature of the magic in the Greater Holy Grail, I don't want black mud!"

Although there is a saying that blackening is ten times stronger, who knows if there will be other problems with the vest.

"I know—"

The drawn-out tone lacked any sincerity.
