Note: I don't own any of the characters, i also used some Japanese history from samurai warriors to make this fanfiction. There won't be dueling because duel monsters will be used in war as weapons. While i will try and cover some of the stories, I will update some chapters again because these chapters are usually written by 1 day and not much checks because I'm busy with life. there will be additional chapters aside from main chapters each character's perspective.(Shingo, Serena, Yuya, Ruri, Rin, Shun and Dennis, more will be added.)

A young man who cross dimension in order to stop the war by bringing entertainment and smiles to everyone, his main goal is to bring peace to the worlds. While facing the harsh reality, his goals never change no matter how fallen he may become even to the point of throwing his intention of bringing entertainment and smiles to everyone and use his katana to cut down the enemy until peace is achieved. Will he able to change the fate of this chaos? Legend of Yuya Sakaki.

Story

During the friendship cup after Yuya duels Yugo and Yugo lost, Yugo died and got absorbed by Yuya although unwillingly then the friendship cup continues and in the end Yuya won.

After the friendship cup and some events, the lancers have finally gather enough allies to storm the academia. They start by attacking the area where the professor imprisons Ruri and Rin. They successfully save them out, but when Yuri attacks them, Yuzu sacrificed herself to let everybody escaped and ended up perished. She was absorbed by Ruri after that just like Yuto, disappear without a trace. Yuya and Serena then furiously attacks Yuri and Yuri got killed by Yuya's odd eyes rebellion dragon and ended up getting absorbed by him.

Due to that, Yuya has absorbed all his counterpart.

Conversation

After absorbing Yuri, Yuya's mind suddenly went blank and he saw Yuto, Yugo and a chained Yuri

Yuto: This is the last time we will be seeing each other…

Yugo: Man this sucks, I really wanna enjoy more….tch..

Yuya was surprised and ask why

Yuto and Yugo then explained that they are finally one, their souls and powers will be 1 with Yuya. While Yuri have his darkside, Yuto and Yugo is going make sure it won't come out by sealing Yuri with them.

Yuya then was really shocked and tried to reply but Yuto, Yugo and the chained unconscious Yuri fused into Yuya and all Yuya can do is shout their names.

Yuya: YUTO! YUGO! AHHHHH!

Story

Then Yuya was back to his senses and they all manage to escape back to the syncho dimension.

Although the academia has suffered major casualties, the lancers also lost one of their most important comrade. Currently, the lancers are in city in the synchro dimension which now is their main hq aside from standard dimension.

Now at the lancer's hq, the lancers are planning a counterattack against academia.

Conversation

While the lancers are in a meeting, Yuya who didn't attend, hides in his room and mourn for Yuzu's death.

Yuya: Yuzu…..

Ruri who passes by after her reunion with her brother, sees Yuya mourning because his room isn't closed then goes to him and cheers him up.

Ruri: I'm very sorry for Yuzu's death…

As Yuya sees Ruri, he instantly hugs her due to the fact she looks the same as Yuzu.

Yuya: Please…. Let me be in this position for a while…

Ruri then hugs him back and rubbed his back to hope to be able to cheer him up. After a while, Yuya finally calmed down and get his senses back. He then blushes and let go of her.

Yuya: So-sorry for hugging you! But I feel better now thank you!

Ruri then smiles at him.

Ruri: You look just like Yuto, a friend of mine.

Yuya then sadly react but thinks she must know the truth. So he explained everything to Ruri about Yuto.

Ruri at first got really sad, but is able to overcome it and give Yuya a smile.

Ruri: I see…. But it's okay because Yuto is within you, even if he's dead, his spirit lives on within you. Just like Yuzu's spirit, I will also do my best to continue her legacy.

Yuya was abit surprised at first, but after seeing Ruri smile, he then have his resolves firmed and think to himself that he must end the war so such sadness will not happen again.

Yuya: They have done too much for me, I must end the dimensions wars so their death won't die in vain.

Story

Since then, a year have passed, a lot of things have change. A lot of the lancers have grown mature due to the fact that they are in war almost every day. Yuya who hangs out with Ruri every time when he is free, falls in love with her while the other hand is the same for Ruri. The academia has been conquering a lot of areas. While duelling is not the same anymore. Instead of lowering enemy's life points, monsters, magic and traps are used as weapons for war. While the duel disk has been modified able to manifest weapons such as swords, bows, guns and many more. This started when the academia modified their sword like duel disks to be able to hurt other people. The lancers also modified their weapons to counter them. Currently in the lancers research centre it's Yuya's turn to get his duel disk modify. But Yuya strongly oppose this because duelling has becoming a weapon for killing and even duel disk can be turn into a weapon and kill.

Conversation 1

While Yuya refused to get his duel disk modified, Reiji speaks to him.

Yuya: No… I don't want to duel like this…. It's just wrong… why can't they surrender if they lose the duel… why must I cut them down…?

Reiji: It can't be helped, the academia, Leo Akaba has become so powerful that we won't be able to survive if we don't fight back. Even if we win the duel, they will cut us down if we don't cut them. Yuya, you are the one who said you want to end the war, is your resolve that puny?

Yuya: I… fine…. I will do it…..

Yuya then hand over his duel disk to the scientists and have his duel disk modified.

Reiji: This katana, it's called the Gilded Talon. It's a legendary katana that can cut down everything you want. Use it and cut down this chaos!

Reiji then implanted the katana "Gilded Talon" to Yuya's duel disk. After Yuya gets back his duel disk, he left the research centre with a long face.

Conversation 2

Ruri who is currently walking around the headquarters because she is protected by the lancers alongside Rin and cannot go out from their vision to prevent the academia from kidnapping her again, stumble across Yuya who just left the research centre. She then greet Yuya with a smile

Ruri: Good afternoon Yuya.

Yuya: uh ya… Good afternoon…..

Ruri immediately noticed Yuya's behaviour and then she asks with a smile.

Ruri: What's wrong Yuya? If there is something bothering you, you could always tell me, I'll do my best to help.

Yuya hesitated but gave in because of Ruri's smile, decided to tell her everything.

Yuya: Alright…. But let's talk somewhere else.

Ruri: Sure, let's head to my room.

Yuya then follow Ruri to her room. Ruri prepared tea and Yuya starts telling.

Yuya: I always want to bring entertainment and smiles to people by duelling… but now… duelling has becoming a weapon to kill….. duel disk are used for killing…. Is this really the duel I wanted…? Is this the only way to end this chaos…? I already killed 2 people (Yugo, Yuri) and even caused my best friend's death (Yuzu)….. how many more people do I need to kill..?

As Yuya talks, he starts to shiver due to the fear of he have to kill even more people. Ruri then put her hand on top of his. This makes Yuya calmed quite a lot. Yuya looked at her then smile.

Yuya: Thanks Ruri.

Ruri: I know I can't help you in this but, you must know you are not alone, I am here if you ever need me.

Ruri then replied with a smile. Yuya then blushed while finally knows what he should do.

Yuya: Thank you Ruri, I finally know what should I do, but first..

As Yuya continues, he stops for a while and blushed but then he bravely confessed.

Yuya: I have one more I need to do, Ruri, I like you for quite a long time and I hope that you could go out with me!

Ruri was surprised because she actually likes Yuya too she then smiled and replies with a blush

Ruri: yes… of course.

Yuya then takes his pendant out and a deck of entermates, and gave them to Ruri

Yuya: Ruri this is my treasure, please hold it until the peace of this land is finally at hands. It's my dream of bringing entertainment and smiles of the people. But currently, peace must be regained to be able to make it come true therefore I'll cut my way to a peaceful world.

Ruri: Yes..!

Story

Another 4 years have passed since then, Academia has even conquered more areas to the point of cornering the lancers to their synchro dimension hq, but it could be worse if Yuya didn't have the resolve to cut down foes. Within these 4 years, Yuya has already cut down uncountable amount of academia soldiers but did not waver because he already promised himself and Ruri that he will cut his way to a peaceful world. This slows down the process of academia to conquer areas, but still not able to completely stop them from doing so.

This time, the professor finally has gone out of patient and personally deploy his troops to crush the lancers, while heading to towards their headquarters, they need to cross through a valley called okehazama near satisfaction town. Due to heavy rainfall and it's too dangerous to proceed, the professor and his massive obelisk forces rest beside the valley to wait for the rain to stop.

Conversation 1

This news is instantly delivered to Reiji by Tsukikage who was scouting the area.

Tsukikage: Reiji-sama urgent news, The academia is currently heading here with Leo Akaba himself leading but due to heavy rainfall, they are currently resting below the valley of okehazama.

This instantly surprised Reiji as he thinks it's a good chance to end this once and for all. He then call out all the lancers officers and start a meeting. With everybody gathers, he starts to discuss the plan.

Reiji: As Tsukikage scouted, Leo Akaba is currently resting under this valley in okehazama, and it's a good chance for us to ambush him from here to here

As he discussed and shows the lancers the map of okehazama while plotting where should they proceed to ambush Leo Akaba.

Reiji: This shall end him once and for all. While the rest of the officers distract the academia, Yuya, Serena, Shingo, Tsukikage and myself will march with small units to ambush Leo Akaba through that valley. Now you will have 1 hour to prepare yourselves before going out to war, dismissed.

All officers: Yes sir!

Conversation 2

After dismissed, Yuya and the other officers head back to each of their rooms to prepare for the march. Yuya immediately heads back to his room, get a wedding ring and head to Ruri's room. As Yuya enters Ruri's room, Ruri greets him but with a worrying look.

Ruri: Yuya…. You are going to march out aren't you...?

Yuya who noticed this, he holds Ruri's hand and give her a smile.

Yuya: Yes, this time we shall succeed, we shall destroy take the professor's head.

Ruri: But…

As Ruri looked at Yuya with a very worrying look that looks like she's going to cry, Yuya then take out a ring from his pocket.

Yuya: Ruri, I will win this war, I swear. I will bring peace to this land. So would you marry me when I come back?

Ruri then got really surprised but end up from worrying to smiling and nodded.

Ruri: Yes..! Of course..!

Yuya then smiled and slides the ring to her ring finger. They looked at each other romantically as they start to kiss then make out. After a while it is time for the lancers to march. As Yuya and Ruri finished making out, Yuya hugged Ruri lightly and then kissed her forehead and bid her goodbye.

Yuya: I'll be back. By that time, please welcome me with a smile.

Ruri: Yes…!

Ruri then smiled at Yuya and bid him goodbye too while wishing deeply for his safety and victory.

Currently, the lancers have prepared to march, as they reconfirmed the plan and head to each's planned destination. Now in okehazama, Gongenzaka, Yaiba, Masumi with the lds armies are currently acting as decoy, distracting most of the obelisk forces by engaging them in war while Reiji, Yuya, Serena, Shingo and Tsukikage leads a small amount of elite forces around the valley and plan to ambush the professor from above.

Conversation 1

Within hours, they arrived the ambush point where professor is resting and when Tsukikage becomes the decoy, they instantly jumps out from the cliff to ambush the professor. Currently the professor who is very loosely guarded due to most of the forces near him is drawn to Tsukikage got surprised by the ambush. The ambush was a success.

Leo Akaba: An ambush?! WHAT?!

As he panicked, the small remaining forces comes out and tries to protect the professor but was instantly killed by Shingo, Serena and their duel monsters. Now the unguarded professor has nowhere to run as Yuya steps closer to him

Yuya: Leo Akaba, I shall have your head! Here I come!

Leo: W-wait! Noooo!

Yuya: Reiji…. Here…

Reiji: well done Yuya….

Reiji then holds the professor's head and show it off the screen as to prove that Leo Akaba has been slain.

This makes the rest of the academia troops led by professor to immediately surrender. After a few weeks in okehazama, the lancers have finally emerged victorious and safely return to the synchro dimension.

Sora: thanks, from now I'll serve you.

While Dennis is currently tied up in front of Reiji, Dennis shows a very unhappy face.

Dennis: I have no interest on what are you going to do in the future, just kill me already!

Reiji then takes out his sword the seventh heaven and cut his ropes down instead.

Dennis: Ah!

Reiji: I forgive you. Your future is in my hands.
