Crossover Anime: I Became Invincible Starting as an Ajin

Fujimaru Ritsuka's eyes widened.

The once calm and gentle girl was now dressed in revealing, form-fitting light armor and holding a large shield.

The surrounding crowd gasped in amazement and took out their phones, flashing their lights continuously.

Mashu covered her face shyly and hid behind the large shield.

Upon seeing Fujimaru Ritsuka awaken, Mashu quickly exclaimed, "Senpai, let's get out of here right away, this is just too embarrassing!"

Mash had vaguely seen a Heroic Spirit appear beside her, and survived by fusing with the Heroic Spirit to become a Demi-Servant.

Thus, it was transferred by the spirit to the Holy Grail War in 93.

At the same time, he became his senior's servant.

However, the Master, who was his senior, was currently unconscious.

The spirit within her told her that her senior was alright, but she needed to wait a while for him to awaken.

Just to be on the safe side, Mashu didn't touch her senior, but waited where she was.

However, this place is a holy land for otaku, which led to a large crowd watching. After all, the Noble Phantasms of Heroic Spirits are much more refined than cosplay, plus Mashu's appeal as a beautiful girl.

Naturally, it attracted the attention of all passersby.

Fujimaru Ritsuka, naturally aware of the gravity of the situation, quickly took Mashu's hand and led her away from the crowd.

After running for a while, the two broke away from the crowd.

"What's the situation now?"

At this moment, Chaldea restored communication, and the doctor briefly explained the current situation to the two of them.

"The explosions at the central power plant and control room just now resulted in a large number of casualties."

"At this moment, there are only a dozen or so employees left in Chaldea who are capable of working."

"All 47 Masters were either seriously injured or killed, and all the executives also perished."

"We were only spared because we were lucky."

(P.S.: What does this mean? It means that slacking off at work can save your life.)

"You have now been transported to Fuyuki City in 93. We are currently observing a large amount of magical energy reaction here."

"At the same time, there is an unknown spirit origin reaction, and the Sheba prediction model... has completely collapsed."

"This point in time seems to have undergone an inexplicable change, and I suspect this place is some kind of singularity."

"You need to gather as much information as possible about this singularity."

"However, you must protect yourselves. I will repair the spirit transfer device as soon as possible and bring you back from that era."

The doctor logged off immediately after finishing speaking.

Judging from the doctor's hurried attitude, Chaldea is probably in a mess as well.

"But, a singularity?"

The inexperienced Master and his inexperienced Servant are now completely bewildered.

"This singularity is quite different from what we imagined."

Logically, every singularity should experience a catastrophic event that could destroy all of humanity, but the surrounding environment appears quite peaceful right now.

Could this place really be a singularity?

"First of all," Fujimaru Ritsuka awkwardly looked away from Mashu, "let's get you some new clothes."

Mashu shook her head: "I seem to have some common sense about this world and some knowledge of how to use magic."

After saying that, Mashu's magic flashed, and her light armor transformed into her usual casual clothes.

For a moment, Fujimaru Ritsuka was somewhat dazed. The peaceful environment and the usual Mashu made it seem as if the horrific scene she had just witnessed had never happened.

"By the way, senior."

Mashu saw something extraordinary from the common sense that came to mind.

"We have come here to participate in a war for the Holy Grail, a war in which seven Masters and seven Heroic Spirits are fighting against each other."

"The final victor will gain the right to use the Holy Grail, thereby fulfilling all their desires."

Fujimaru Ritsuka naturally knew all this, but now, looking at the public calendar on the shop next to her, she was stunned.

"I remember the first Holy Grail War was supposed to be held in 2004, wasn't it?"

Mash replied instinctively, "That's right, it was indeed the first Holy Grail War held in 2004."

But when Mash looked in the direction Fujimaru Ritsuka was pointing, she froze.

The calendar shows that this is Fuyuki City in 1994.

"How is this possible?"

History has actually changed?

Has the Holy Grail War started earlier than planned?

However, the common knowledge that the Holy Grail bestows upon Heroic Spirits does not provide an answer to this question.

Fujimaru Ritsuka made a decisive decision.

"We need a breakthrough, a breakthrough that can tell us what is really happening in this world."

……

The Einzbern family

The castle, which had been previously invaded by Aozaki Aoko (actually Aozaki Touko), has now been repaired by the powerful productivity brought by magic.

On this day, the Anzbern family was on high alert.

To prevent a repeat of the previous attack.

The magic workshop located within the castle.

Emiya Kiritsugu, Einstein, and Maiya were next to a magic circle.

The magic circle had been prepared long ago, and a huge blue and gold patterned sword sheath was placed in the center.

"Preparation begins."

Magic activated, incantation performed, summoning...

After the great light faded.

Within the original magic circle, a slender yet upright girl stood with long, golden hair styled in a classic updo and encased in platinum armor.

She opened her eyes and asked, "Are you my master?"

……

Inside a luxurious hotel.

As the elite of the Clock Tower.

Director Ken has arrived in Fuyuki City and has summoned his own Heroic Spirit.

(P.S.: Director Ken is pretty awesome (the more awesome he is, the more miserable he is), I won't go into details to fill up the word count, most Fate fans know this, or readers can leave a brief explanation here.)

Even if the relic is chosen temporarily, it will still summon one of the three riders, Lancer.

Even though he had anticipated it, Director Ken still underestimated the abilities of this Heroic Spirit.

Even so, there was still some regret in my heart. If the Heroic Spirit summoned by the carefully prepared relics had been stronger, it might have been even stronger.

(P.S.: What does this teach us? Always sign for the package in person.)

All the magic props he prepared were based on that sacred relic.

"I didn't expect the summoned heroic spirit to be so good this time."

His fiancée's voice came from behind him, this time in order to increase his chances of winning.

Director Ken is currently renovating the entire building, and now only the twenty-fourth layer of the magic barrier remains to be completed.

The entire Catherine Hotel has been transformed into a colossal structure, demonstrating Director Ken's seriousness about this war.

Normally, no normal person could break through this terrifying fortress.

Even the weakest heroic spirits will face a tragic end here.
