I use Yugioh to battle the multiverse

Feeling this through Shidou's senses, Katsu couldn't help but look up, looking at the source of the black in the distance, and sighed---

"It seems that you already know some incredible truth---"

"Shidou, when was the first time you met Origami?"

"Eh...? ...It was when I changed classes at the beginning of the second year of high school--"

"Maybe you thought it was the first time you met, but Origami actually knew you for a long time?" Katsu spoke with his eyes half closed.

"Huh?" Shidou was a little confused.

"...I thought about it carefully and found a lot of clues...Our time and space, and the time and space you are in now, should be the real past and future relationship...What you are doing there now is probably what really happened five years ago..."

Hearing Katsu's shocking words, Shidou's mind couldn't help but feel a little confused. After a while, his eyes gradually became clear again.

"Ah---it seems... like that?"

Because Shidou just recalled that in his memory, when he and Origami "first met" at the beginning of the second year of high school, the way Origami looked at him was not the look of a first meeting... but the look of "reunion after a long separation"---

Because──Origami had already met him at "this time" five years ago.

"The reason why Origami hates spirits, the fact that you met Origami, and the main factor in constructing the original world are all related to Kurumi's power. If Kurumi hadn't sent Origami and you back five years ago, the original world would not have been formed..."

Katsu continued to whisper with his eyes half closed---

Just as Katsu said, if there was no spirit called Kurumi and no angel called Kekeketei, the world that Shidou and others lived in might be completely different.

"But, Tokisaki-san's original intention..."

"Of course not. What are you thinking? No matter what, you can't blame my Kurumi. If you want to blame someone, blame this damn world."

"… …" Shidou was speechless. ...

After a while of silence, Shidou gradually recovered, and then his eyes gradually became empty. After a while---

"Katsu...I think I messed up?"

"Tsk---Okay, Shidou, don't think too much, you've done a good job---Next, leave it to me."

"Huh?" Shidou was puzzled.

"I... will ask Kurumi to take me there---"

When Shidou heard this, he was stunned for a moment, and asked in a daze: "Send it over... where to send it?"

"Five years ago, of course."

"…!…Do you want to…come to my current time and space?"

"No, I will go to a few minutes before your current timeline and stop Origami from killing her parents." Katsu's voice was still weak, but also firm.

"…But, your body…"

"Oh, it's okay. Who do you think I am? It's just a small matter. Don't worry about it at all."

"…Is…really? Well - then…be careful."

… …

"Come on, Kurumi, I will change this ending, distort this damn time and space, and destroy this world created by fate!" Katsu looked at Kurumi with burning eyes.

"… …" Kurumi looked at Katsu quietly, with a gleam in her eyes. She did not stop Katsu, nor did she persuade Katsu. She just raised the classical pistol in her hand, and supported him in action. No matter what, she would unconditionally support Katsu's decision.

"Well---come out! [Zafkiel!]"

As Kurumi called out, a golden bell emerged from behind her ---

Then, Kurumi raised her hand---

"Wait---Kurumi, use my spiritual power, just like Shidou did before, you can directly extract my spiritual power." Seeing that Kurumi had no intention of summoning City of Devouring Time to absorb her spiritual power, Katsu spoke quickly.

"Ah, Shidou is Shidou, and Katsu is Katsu. How can their treatment be the same? Don't worry, it's just going back five years. It won't take up too much spiritual energy." After saying that, Kurumi didn't give Katsu time to react.

"[Ninth Bullet], [Twelfth Bullet]!"

Bang! Bang!

Two consecutive gunshots were heard, and two bullets emitting a light golden glow flew out and hit Katsu's body---

"… …"

… …

… …

This is a very mysterious feeling, as if sitting on a small boat, shuttling through a river, and when it reaches a certain point, the boat seems to want to dock, but for some reason, it seems to hit an invisible cover and the boat is bounced away. Then, as if being pulled by something, it moves forward to another point and slowly docks.

Different from the feeling of using his card to time travel in which he travel over the past instantly.

When the feeling of weightlessness and mystery faded away, Katsu heard a "whoosh" sound coming from his ear---

Needless to say, Katsu knew that he was in mid-air.

He opened his eyes and found himself falling face down to the ground ---

As a result, he was stunned to find that on the street, a blue-haired boy was looking at him with his mouth wide open.

Nearing the ground, Katsu endured the severe pain in his body and activated his magic power. Before touching the ground, he paused for a moment and then landed quietly. However, his body softened and he knelt on one knee on the ground.

"Cough cough cough cough--!" He coughed violently for a while, and coughed up some blood foam.

"Katsu!" A familiar voice came from not far away. Katsu wiped the blood from the corner of his mouth and looked up. It was Shidou, who was running towards him with a strange and worried look on his face.

"Katsu---!" Shidou came over and quickly helped Katsu up. "Are you okay?"

Katsu stood up with the help of Shidou and waved his hand: "It's okay."

"Huh--that's good, but... why are you here? Didn't you say... that you can go back to a few minutes in the past relative to the present?" Shidou asked in confusion.

"… …" Katsu was stunned for a moment after hearing this, then he glanced at Shi Dao, then looked up at the sky: "Maybe…something went wrong… …"

"Kurumi...Kurumi ? Can you hear me?"

Speechless---

A few seconds later---

"Ah, Katsu? Something went wrong just now. It took some time to connect with your consciousness... and the timeline was also a little wrong. 

Something pulled you over her, so you are now in the timeline where Shidou is---"

"Ah, this..." Listening to Kurumi's words in his mind, Katsu couldn't help but blink his eyes, and then naturally recalled the wonderful feeling after being hit by the Twelfth Bullets before---

When it reached the node for the first time and wanted to dock, it was affected by elastic force. The second time, it was affected by traction.

"Ah... I can probably guess the reason---" Katsu's mouth twitched, and then he muttered: "What should we do now?"

"…Well, don't worry. There is another way. Katsu-kun, you and Gokawa-san should go together to find [me] at that time."

"…ha?"

… …

A few minutes later, Kisara carried Katsu flying up the building that stood near the fire scene.

"Hu... Hu..." Shidou moves continuously using the escape route in the building to travel. The summer heat and the high temperature of the flames mercilessly took away his physical strength.

Shidou arrived later while Katsu waiting for him.

Soon, the Shidou arrived at the top floor of the building and looked around breathlessly.

"Is it here...?" 

"Yes, I think it should be right."

"Should be...Okay, I believe you she won't cheat me..."

From the top floor of the building that seems to be overlooking the residential area, you can clearly see the scenery of the Town where the fire is still raging.

The sirens of fire trucks and ambulances blared nearby, making the streets unusually noisy in the evening.

It was horrible---after looking away, Katsu turned around again to look at the top of the building in order to make sure he missed anything.

However, I saw nothing.

"Is Tokisaki-san really here?"

"Cough cough cough...ah, since Kurumi said so, it shouldn't be wrong." Katsu said after coughing for a while.

"Is that so..." Shidou nodded and murmured, but before he could finish his words, he stopped abruptly.

Because he felt a chill down his spine and couldn't move on the spot.

"…Ah—"

——There was someone behind him. Shidou instinctively sensed this, swallowed his saliva, and held his breath.

At the same time, Katsu's right eyelid also twitched violently---

Then, as if responding to their premonition, a voice came from behind that sounded very interested in the visitor.

"Ah-ah." A familiar voice sounded behind him.

Katsu and Shidou slowly turned around----

"Oh, I didn't expect that there would be guests coming to a place like this. It's really rare." After saying this, Tokisaki Kurumi showed a charming smile.

"Why did you appear here Kurumi" Katsu asks the Kurumi in the future.

"To see the fire?"

"Because such a serious disaster may be related to the spirit. Anyway, I was in that area five years ago. However, I did not meet Katsu... I can guarantee this. But──no, this action is meaningful because of this."

"What do you mean?"

"Think about it. If you met me, who you shouldn't have met, just like this, even though it's just a trivial thing, history has indeed changed, right?"

"Maybe...it's true."

Katsu took a deep breath, and then stared intently at a girl standing on the top floor of the building, his eyes revealing a hint of joy and a hint of nervousness---

I was happy to see Kurumi from five years ago, but he was nervous because Kurumi at this time didn't recognize him... Katsu knew that Kurumi was not an easy person to get along with. Don't be fooled by her docile appearance when she was with him, that was only towards him... But the current Kurumi didn't recognize me, and she was completely different towards strangers.
