I use Yugioh to battle the multiverse

Shidou scratched his hair while walking on the road, and couldn't help but speak through the mysterious connection in his mind: "Katsu, that just now..."

However, before Shidou could say a word, a red light suddenly flashed in the sky, and Shidou's attention was instantly drawn away, and he suddenly turned around to look in that direction.

I saw a huge pillar of fire standing on the other side of the roofs of the densely packed houses. The next moment, the pillar of fire splashed in the air, and the surrounding area was invaded by heat waves.

The flames instantly surrounded the entire vast town, burning houses and trees. There were several wails and screams in the vicinity, and the residents of the town began to take shelter at the same time.

"Is this... the flame created by Kotori?!" Shidou suddenly stopped asking Katsu about the future Katsu...

"It seems... that's right." Katsu, who also saw this scene through Shidou's senses, narrowed his eyes and responded to Shidou.

Shidou gnashed his teeth in anger. It seemed that Kotori had already gone to the park before. And just now, she was transformed into a spirit [Phanrom].

"Hmm...!" Shidou felt uneasy and started running on the spot.

----Because Kotori has become a spirit, it means that the [Phantom] is there──and Origami will travel through time and space to this place.

However, the road was blocked by a large number of residents seeking refuge and houses collapsed by flames, making it impossible to move forward smoothly.

Shidou searched for the few vague memories from five years ago, and finally took a long detour to arrive at the park mentioned before.

"...! That's──" When Shidou arrived at the park, four people had already arrived before him.

One was the sobbing young Kotori, and the other was Shidou five years ago lying on the ground and shota Katsu.

And --- standing and looking down at the three of them, "something" in the sky with the silhouette of a human.

"[Phantom]!!" Just as Shidou called out this name── a ray of light poured down from the sky, and then the figure of [Phantom] disappeared in an instant.

Shidou felt sparks flying in his mind. Yes, Shidou had seen such a scene before.

Five years ago, there was indeed light shining from the sky towards [Phantom].

Shidou suddenly raised his head, as if searching the sky for the source of the light just released.

Then, a figure appeared. It was a beautiful girl wearing a dreamy white dress and carrying many things that looked like "feathers".

However, her features were now tinged with resentment from emotions like hatred and anger.

"Origami!!" Shidou couldn't help but shout loudly. That's right, the one staying there was the spirit, Tobiichi Origami, who traveled through time and space from the original era.

The process of how Origami turns into an spirit is still a mystery. However, the Origami has not yet turned into a reversed form.

He was afraid that something would happen next. Something would happen that would make Origami, the resolute girl, fall into the abyss of despair.

In addition to Origami, Shidou also saw the "Phantom" that had just disappeared in the sky. It must have dodged Origami's attack and escaped into the sky.

Origami just waved her hands, and the "feathers" floating around her immediately released light towards the "Phantom".

As if taking this as a signal, the two began to dash around in the air.

"Shidou, hurry up and catch up, or you'll lose her."

"Okay... I understand!" After hearing what Kurumi said, Shidou reflexively chased after the two of them and ran on the burning street again.

Origami fired beams of light at the Phantom one after another, but the Phantom seemed to just keep dodging the attacks without making any decent counterattacks. It was like playing a game of chase, flying all over the sky.

"Origami! Origami! It's me! Listen to me! You can't keep doing this!" Shidou chased after the two and yelled at the top of his lungs, but Origami didn't respond at all. However, that was only natural. The distance was far enough to begin with, and what was more, the person in front of Origami was her enemy, whom she had hated more and more for many years.

Even if it's Origami, it's not surprising that you don't notice what's happening around you.

But even so, we can't give up. Shidou desperately chased after the two figures and shouted:

"Origami! Origami!"

"Origami!" Just at this moment── "Huh...?" The voices of others calling Origami suddenly came, causing Shidou to stop and shift his gaze back to the ground.

I could see a man and a woman who looked like a couple. They must have escaped from their home which was on fire. Their clothes were dirty and they had many small scars on their bodies.

Shidou was confused for a moment as to why they were calling out Origami's name, but──he immediately knew the reason.

Because in front of them stood a girl who was about the age of an elementary school student.

She has shoulder-length hair and seemingly smart facial features.

That's right, that's… what Origami looked like five years ago.

"Dad, Mom──!" Origami's eyes welled up with tears. She was happy that her parents were safe and sound, and called out to them.

However, the next moment── Shidou felt that his vision was instantly dyed pure white.

boom!!!

A terrifying explosion sounded, and Shidou couldn't help but close his eyes and shrink his neck. After a while, until the explosion stopped, he recovered and followed the sound again---

He discovered to his great horror that countless golden lasers suddenly rained down from the sky---

Shidou quickly rolled backwards to avoid a beam of light, and then quickly looked to the other side---

As a result, what he saw made him breathless...

Several consecutive beams of light pierced through the couple - Origami's parents.

Shidou's eyes widened, his mouth slightly opened... At this moment, he almost didn't dare to look at Origami's expression----

"Ah…ah…ah…ah…ah…ah…ah…" Origami made a hoarse sound---

Then, he gritted his teeth and raised his head to stare upward at the source of the light.

Then, "Angel..." Origami looked up at the sky and whispered softly. After hearing Origami's voice, Shidou also raised his head reflexively, his voice trembling: "...! Could it be..." He shivered as if a bug was crawling across his skin.

He saw... the figure of the spirit Origami wearing pure white spirit clothes.

From here, it is impossible to clearly see the appearance of the spirit that emits light. Five years ago, Origami could only barely see the outline of a human figure. People who don't know the existence of spirits would describe that figure as an "angel", which is perhaps understandable.

"It's... you..." Origami collapsed on the ground, her innocent eyes filled with intense hatred, and she shouted loudly: "I can't... forgive...! Kill you...! I──will definitely kill you...!"

The voice shouldn't have been able to reach high into the sky, but Origami, wearing a pure white spirit outfit, was shaking her body as she uttered the words.

If someone who doesn't know the situation saw this scene, they might think she was laughing.

However, Shidou knew very well in his heart that the spirit could not be laughing.

"How could this be...?" Shidou couldn't help but take a step back, making an increasingly unbelievable sound--

In just a few seconds, he understood all the causes and consequences.

Origami returns to the scene where her parents were murdered five years ago, trying to change the facts. However, Origami learns that the real murderer of her parents is... herself.

"This world... is very cruel to her," Katsu murmured with mixed emotions, and at the same time, he noticed that Kurumi's grip on his hand had slightly increased.

Katsu wiped the sweat from his forehead, and at the same time, he rubbed Kurumi's soft and tender hands for a few times to comfort her---

"Ahem... It's not your fault, don't blame yourself." 

"… …" Kurumi didn't say anything and remained silent for a moment.

Seeing this, Katsu endured the pain in his body, struggled to stand up, and gently embraced Kurumi in his arms---

"You helped Origami go back to the past just to help her fulfill her wish... It's not your fault." Katsu patted Kurumi's back and stroked her hair to comfort her: "It's not anyone's choice for it to become like this. No one is wrong. The wrong thing is this world that plays tricks on people..."

"...Well...but--after all, this is due to my fault...ah---it's really unpleasant..." Kurumi sighed, then rested her exquisite and perfect chin on Katsu's shoulder, and hugged his waist---

"Don't worry I will solve this problem---"

… …

Shidou suppressed the hesitation in his heart and looked up at the sky. He hoped to find Katsu's figure --- Katsu of the future ---

If Katsu was here... there would definitely be a way---Shidou believed this firmly.

However, all the figures in the sky disappeared at this moment, not only [Phantom] but also Origami, all disappeared.

Leaving only Shidou here.

"It disappeared... Origami also..."

"The time limit of the Twelve Bullets has been reached, and Origami should have returned to the era to which she belonged." Katsu's voice rang again in Shidou's mind.

"Is that so... Katsu... I... what should I do now?" Shidou lowered his head and glanced at the small Origami not far away with reluctance.

However, after this glimpse, Shidou could not take his eyes away immediately --- because part of the burning and collapsed building fell towards Origami five years ago who was slumped on the ground.

"--Origami!" Shidou shouted immediately and rushed towards Origami, and the two of them fell to the ground.

The next moment, the burning building materials fell towards where Origami had just been, stirring up a cloud of dust and sparks.

"Ugh...!" It's too dangerous to stay here any longer. Shidou coughed and held Origami's hand, running on the streets that were dyed red. He finally stopped when he reached a place where the flames had not spread, and then Origami fell to her knees helplessly.

"Hu...Hu...Are you...are you okay, Origami?" Shidou said this before realizing his mistake.

Although she took action instantly, Origami of this era probably didn't know Shidou yet. Calling out her name might not be a good idea.

However, Shidou's worries were unfounded. Origami didn't seem to notice that a stranger was calling her name, and she just looked up at the sky with trembling eyes.

No, to say that she was empty was probably not the right way to describe it. Anger, resentment, loss, sadness—all the negative emotions that a human could have were mixed together, clouding her eyes.

"Dad...Mom..." Origami opened her dry lips and uttered a weak sound.

That look was too heartbreaking, Shidou couldn't help but frown--

"...Origami!" Shidou was at a loss, not knowing what to say. However, he knew that he could not just leave her alone. 

Shidou half-subconsciously hugged Origami tightly with both hands, as if to suppress her turbulent emotions, and hugged her tightly with his trembling hands.

"...You...are..." Origami finally seemed to notice Shidou's presence and made a small sound.

"It's okay! It's okay, so...!" Shidou hugged Origami tightly, he knew that this sentence was too irresponsible, but he just couldn't help saying it.

The girl is so petite that even Shidou, whose body has shrunk, can hug her tightly with both hands. The world she has to face is too cruel and ruthless.

The difficult road that this girl must take in the future and the "truth" that she will eventually reach, this ending is too cruel, so Shidou can only shout: "Origami... one day... you will definitely find out... the truth of everything...! But──don't forget! You are not alone...!"

"What are you... talking about... Origami responded to Shidou with a confused voice. This was understandable. However, Shidou couldn't stop talking.

"Your sadness will be borne by me...! Your anger will be received by me...! If you feel lost, rely on me! If you are faced with a helpless situation, call me! It's okay to vent it all on me! So, so──" Shidou hugged Origami tightly and continued: "Don't ever feel despair...!"

Origami listened to Shidou in a daze, but soon she began to tremble slightly: "Ah... wu... ah... wu wu... wu ah ah... ah ah ah...!" Origami grabbed Shidou's clothes, buried her face in his chest, and began to cry with a suppressed sound.

Maybe it was because Shidou's appearance relaxed her tense mood, or maybe it was because the sadness of losing her parents came flooding back. Shidou couldn't judge, but at this moment, Origami finally showed the emotions that a little girl of her age should have.

"Dad... Dad... Mom...──" "Origami..." Origami sobbed, and Shidou put more force on his trembling hands and stroked her back.

Then──I don't know how long I did this, "...Thank you..." Origami, who had been crying for a while, said this softly, let go of Shidou's clothes, and stood up. Then she wiped her tears with her sleeves, and turned her red eyes towards Shidou.

"Who...are you?"

"Ah, uh... well -" Thinking about it carefully, this is a natural question, but when someone suddenly asked this, Shidou didn't know how to answer it. Because he hadn't thought of this answer, he immediately rushed out.

It was no use just pretending to be stupid, so Shidou made up his mind to look back into Origami's eyes.

"I'm... Itsuka Shidou, and I live nearby."

"Itsuka... Shidou." Origami murmured as if she was thinking over Shidou's name again and again, then turned around.

As if──she didn't want Shidou to see her expression.

"…Is what you just said true?"

"Eh…?"

"Are you willing to take it all?"

"Yes... yes...! Of course it's true." Hearing what Origami said, Shidou nodded greatly. Although it was a semi-subconscious blurt out of his mouth, what he said was from the heart.

"Is that so? Then──" Origami still didn't let Shidou see her expression, and continued: "My tears are in your hands; my smile is for you; and please take all my happiness and joy with you."

"Eh──?" Shidou widened his eyes upon hearing the unexpected words.

"—This is the last time I will cry, and the last time I will smile." Origami said and turned back to look at Shidou.

Seeing her tear-stained smile, Shidou was speechless. Origami turned her head away again.

"But this anger is mine; this ugly emotion belongs to me alone. No matter how long it takes, no matter what means are used, I will... kill her, kill that angel."

Angel. When Shidou heard this word, his fingertips trembled slightly. However, he couldn't say it out loud. He couldn't say that the spirit was the future Origami. He couldn't tell this young girl.

"So, before then, please keep those feelings until I - kill the angel." Origami said with her back to him.

"Origami---" Shidou could only call her name in a daze.

The young Avenger left Shidou alone and walked away.
