Awakening the mysterious **Reincarnation System**, he regained memories of a past life and the truth of his existence. He wasn’t just another student—he was a traveler, a reincarnator destined to walk the path between worlds.His journey began in the brutal Warring States Period of the Naruto world, where blood and war shaped legends. But that was only the beginning. With each reincarnation, he would step into new universes, face gods and monsters, and carve his name across the multiverse.From the shadows of history to the frontlines of cosmic battlefields, Su Xiuyu would rise, one world at a time.

Nine Realms Sword Emperor, a legend returns, leveling everything.Genius monsters, trampled underfoot, powerful beings, wiped out with a wave of a hand.If people do not offend me, I will not offend them; if people do offend me, annihilate their entire family.

On one spring evening when I was eight years old, I, Erica, Duke of Aurelia’s daughter, realized something.

Huh, I have reincarnated into a fantasy world, haven’t I?

Moreover, it was the romance-fantasy girl game that had the reputation of being bloody, 『Liber Monstrorum ~Phantom Beasts and the Winter Princess~』

The face reflected in the mirror was that of the villainess character of that game.

After repeatedly harassing many characters, including the heroine, she would die without exception, signaling the beginning of an event called the bizarre incident. She was a villain who deserved to get the consequences!

—I absolutely don’t want a destiny like that, though?

No, for me who has remembered the memory of my previous life, there would be no such thing.

In my previous life, I was harassed immensely by an irrationally angry yandere man who proclaimed ‘She is absolutely in love with me.’

My cause of death, too, was from being stabbed by another yandere man who I only had talked with a few times……

Now that I have become the haughty villainess Erica, I shouldn’t encounter more misunderstandings like with the previous life’s yandere men anymore, right……?

In that case, it will be fine as long as I deal with the death flags that I may have raised myself.

All right! First of all, before the bizarre incident begins at the Magic Academy, I will strike down the death flags accordingly!!

—Or so I thought, but it seems that I am about to die.

Eeh, how did this happen—!?

“We need to go back and inform others of what just happened. Whatever happened has happened and can't be changed back. This involves the death of an ancient being. We won't be able to change it as it was a Nexus Event and TVA won't be able to control it. Loki, are you still at the throne?” John shouted.

Unsurprisingly, Loki appeared out of nowhere. TVA was responsible for all Nexus Events and Beings. And this was a huge Nexus event. The point of no return, just like the death of Christine in What if?

“You have commited quite the crime John. This crime according to the laws of TVA would have you pruned instantly, with no questions asked and no trial.” Loki said with a smile.

“It was not me who did this. It was him. Why am I being put in the tough spot?” John asked with a sharp tone.

-------------

When a cinephile and an otaku/weeb travels through dimensions and gets a system which can only be described as overpowered but comes with restrictions. At first he was overjoyed with the system but soon realizes that he is in a very dangerous world where his life was at risk all the time.

(There will be no change in the canon until the New York War ends)

Disclaimer : I am not an economist so I might have done some mistakes in the economics section of the story. If you have suggestions to make it better you can leave in the comments.

Warning - The MC won't be OP from the start itself and will grow to a powerful character in due time. The starting feels a bit weird because I am totally new to writing a novel and English is my second language. I don't have an editor so the conversations and descriptions might be little stiff. I am trying to improve.

P.S. This story is based on Marvel universe
