Crossover Anime: I Became Invincible Starting as an Ajin

In the original work, Matou Kariya is portrayed as a devoted lover.

He and Tokiomi Tohsaka's wife, Aoi, are childhood friends.

(P.S.: Actually, Aoi's relationship with her childhood friend was also arranged by Matou Ryokon.)

In modern terms, Matou Kariya would be described as a loser.

His feelings for his childhood sweetheart remained unchanged even after she married, and he transferred those feelings to her daughter, Matou Sakura.

(P.S.: I'll just briefly mention it here. Actually, Kariya's feelings for Sakura are quite complicated, but readers who haven't read Fate shouldn't get the wrong idea. Kariya is just an ordinary person with no fetish or perverted psychology.)

However, unlike some terrible and vulgar plots, Matou Kariya actually regrets the outcome but is not unable to accept it.

In his opinion, even if he married Aoi, could he find happiness in the Matou family, a den of insects?

After running away from home, she kept in touch with Aoi through letters until she heard that Sakura had been adopted by the Matou family.

To some extent, Kariya Matou was one of the driving forces behind Sakura Matou's tragedy.

Even if he didn't do it intentionally, his actions undeniably caused this to happen.

Having gotten into the series through the anime and then catching up on the manga, Wang Bai decided to give a brief overview of what happened to Matou Kariya before he participated in the Fourth Holy Grail War.

Matou Kariya is just an ordinary artistic young man.

During my school years, I was relatively unknown and wrote some literary pieces. During my teenage years, I wrote "The Dark Swordsman Kalia - The Awakening of Evil Heart" (it's hilarious that the protagonist is a dark character, almost like an anti-hero).

Kaname and Tokiomi (who later married into the Tohsaka family and is Sakura and Rin's mother) are childhood friends. Tokiomi Tohsaka is the student council president, and Kariya Matou also harbors feelings of envy and jealousy towards Tokiomi Tohsaka.

(By the way, it was arranged by the old man that Aoi became Kariya Matou's childhood friend. Considering what happened later, it really shows that being old and not dead is a thief. Disgusting, disgustingly disgusting.)

Later, due to feelings of envy, admiration, and jealousy towards Tokiomi Tohsaka, she developed a dislike for the magic of the Matou family, refused Matou Reiken's arrangements, and ran away from home until she returned home because of Sakura.

Kariya Matou was forced by Ryokonomi Matou to eat the Crest Worm cultivated from Sakura's body for Sakura's sake. In order to strengthen his tendency to summon the Berserker Heroic Spirit, he even said, "You didn't marry the woman you loved, but you have the first worm of the daughter born to the woman you loved in your body."

He deliberately provoked Matou Kariya with those words.

(I've said it many times, but I still have to say it's disgusting, truly disgusting, Matou Zōken)

What follows is the process of Matou Kariya burning his life force in battle. After all, the Crest Worms feed on magic power, which is called "small source" in the Type-Moon world and can be understood as life force.

Afterwards, she was mocked by Tokiomi Tohsaka (who was unaware of the matter of the Insect Cube) using Sakura as a pretext, who said that it was Kariya's fault that Sakura went to the Matou family. She was framed by a certain priest and killed Tokiomi Tohsaka. She was also misunderstood by her childhood friend Aoi, whom she admired, and was scolded on the spot.

Participating in the Holy Grail War, which offers no benefit whatsoever, is solely for the sake of bringing happiness to one's beloved. However, all one's actions contradict this happiness and are even rejected by the very object that bears that happiness.

For Matou Kariya, it was no different from being betrayed by the entire world.

In short, Matou Kariya eventually died of a mental breakdown.

He had Shinji Matou prepare a room and placed Sakura Matou inside it.

Wang Bai didn't know what Matou Ryouken had done to make Matou Sakura unconscious, so he didn't dare to make any rash moves and prepared to let her gradually wake up.

During this process, Shinji Matou took the phone and said, "Big brother, Uncle says he wants to talk to you."

Wang Bai answered the phone, and a voice came from the other end, clearly probing and wary.

"Who are you? That guy, Matou Reiken..."

Even though Matou Kariya is in a terrible situation, it doesn't mean Wang Bai will argue with him.

"Sakura, as Aoi's daughter, was adopted into the Matou family. Are you coming?"

The other person paused for a second: "Come on."

Then Wang Bai hung up the phone.

You think I can't mess with you after I've completed the entire game?

After hanging up the phone with Matou Kariya, Wang Bai felt like he had been in this place for quite a while.

Wang Bai planned to return to the world of demi-humans to take a look.

He tried to open the membrane as before, stepped inside, and found himself still in the room.

???

Wang Bai was surprised. Had he opened it wrong?

After sensing for a while, I discovered that the information on the other side of the membrane was indeed from the demi-human world.

The ability to discern information about the world one has visited is an instinct naturally acquired while traversing the membrane.

After trying again, Wang Bai realized that he had been outmaneuvered.

As you cross to the other side of the membrane, it seems as if another force turns the passage around and connects it back to where it started.

Wang Bai realized that someone or some force was preventing him from leaving.

Could it be Yustissa?

But Yustissa doesn't have that ability at all.

If Justisa had the ability to stop him from traveling through time, wouldn't he have already reached the outer world?

Why bother with a large Holy Grail system to secretly drill holes?

Moreover, the only entities capable of performing this operation are likely the two major restraining forces and mages.

As he thought about it, Wang Bai started to sweat.

No way, what makes him so special that he'd be targeted by someone of that caliber?

This is terrifying.

They probably didn't care about the skills of someone as insignificant as him.

Are they abandoning Lostbelts? Are they abandoning Steel Land?

He's just an illegal immigrant; what right did he have to offend these two powerful figures?

Wang Bai calmed down and realized that if the other party really wanted to kill him, he would probably die the next day because he landed on his left foot first after getting out of bed.

Then there must be something that Wang Bai needs to do.

There's only one thing that could be associated with him and be considered as saving the world.

The Holy Grail.

However, the Holy Grail War is still a long way off.

As far as I remember, the Fourth Holy Grail War was around 1994, which is about a year ago now.

If it's a year, the world of demi-humans shouldn't have too many problems.

I hope there's no issue with the flow of time between the two worlds, or if there is, I hope time flows more slowly on the other side.

While Wang Bai was thinking, Matou Shinji ran back from outside, but this time he brought someone with him.

However, Wang Bai didn't have much of an impression of this person; he probably just a minor character from the original work.

Wang Bai asked directly, "Who goes there, and what brings you here?"

Matou Tsuruno was stunned by Wang Bai's question.

You're the one who came here, aren't you?!
