What if Tanjiro was a Pure Saiyan? (DB X KNY)

The Beginning of The End

"Namu... Amida Butsu!"

- Gyomei's Memory (narrated by him) -

"The first time we met... Ubuyashiki-sama was 14 and I was 18. It was hard to believe from his bearing and behaviour that he was four years younger than me. The words he said to me when released me were, 'I know that you fought to protect people. You are not a murderer.' He always... knew what people wanted to hear... at that moment. His solemnity never changed from the first time we met until his death."

Gyomei sat beside Kaguya, who was in bad shape. Kaguya told Gyomei, "Within five days... Muzan will come. Use me... as bait... and kill him." Gyomei asked, "Why do you think he'll come?" Kaguya chuckled and said, "Instinct... That's all. Not... reason."

"In addition to that special voice, the Ubuyashiki clan had an incredible instinct. It was also called recognition. The ability to see the future. In this way, they became wealthy and avoided crisis many times."

Kaguya weakly said, "The other... children... will not agree... to use... me... as bait. I can only ask... you... Gyomei." Gyomei thought about it for a bit but then he began to tear up. He also said, "Very well. If that is your wish, Master." Kaguya said, "Thank you. Please... from now on... do not let... my dear... children die."

- With the coming battle (no narration) -
Gyomei's spiked flail crushes Muzan's head. It grew back as fast as it was crushed and Gyomei thought, "I knew it!! Just as Ubuyashiki-sama foresaw... Muzan... he... Even if you sever his neck... he doesn't die!!" Gyomei then remembered Kaguya's words,

"I suspect that the only thing that can destroy Muzan... is sunlight. If he doesn't die when you cut his head, the fight is going to go on until sunrise."

Gyomei thought, "And the speed of his physical regeneration... Judging by the sound... It far surpasses any demon I have faced so far. Even after Master and his allies... blasted and weakened him, Muzan still has this much strength. Until dawn breaks... we must restrain this monster in a place where the sunlight will shine." Muzan reached his hand out to Gyomei and used,

"Black Blood Brambles!"

Attacks that looked like barbwire came out of Muzan's hand and went after Gyomei. Gyomei then used,

"Stone Breathing-"

Gyomei was cut off by a huge explosion I'm between him and Muzan. Gyomei noticed that most of Muzan's attacks were stopped and he senses that it was Tanjiro who did that. A yellow light then occurred and pushed the dust away. Tanjiro yells, "Muzan! I will kill you right here and right now!" Muzan smiles and says, "Why don't you try me, Tanjiro Kamado!" But before Tanjiro could attack Muzan, he felt the other Hashira's presence. He then heard Sanemi yell, "Was it you?! What did you do to Ubuyashiki-sama?!!" Gyomei thought, "The Hashira gather! Ubuyashiki-sama commands... splendidly." Mitsuri and Iguro appear from the treeline and both yell, "Master!" Gyomei begins to inform everyone, "It's Muzan!! Muzan Kibutsuji!! Even if we cut off his head, he won't die!!" After Gyomei finished, Kyojuro, along with Giyu and Shinobu, all appeared and had the look in shock. Everyone had the same thoughts but still kept up with their charge at Muzan. Everyone begins to use their respective techniques,

"Mist Breathing, Fourth Form!"

"Flame Breathing, First Form!"

"Insect Breathing, Butterfly Dance!"

"Serpent Breathing, First Form!"

"Love Breathing, Fifth Form!"

"Water Breathing, Third Form!"

"Wind Breathing, Seventh Form!"

"Hinokami Kagura, Sunflower Thrust!"

Muzan then smiles as shoji doors open up underneath everyone. Everyone falls in as Muzan yells, "Do you think you have me cornered? You're all going to hell!! Tonight, I am going to kill every last one... of you filthy Demon Slayer!" Tanjiro yells, "You're the one going to hell, Muzan! Once I find you, I'll never ever let you escape from my sight! And then I will take you down!" Muzan says, "Then do it if you can! Tanjiro!" Tanjiro floats and thought to himself, "Giyu! Where is Giyu?" Tanjiro then saw Giyu and Kyojuro and landed beside themm. Before Tanjiro could greet the two, a demon appears behind him but Tanjiro slashed the demon's neck. Numerous other demons bashed a door down and charged at the two. The three got a firm grasp of how many demons there were and all used,

"Water Breathing, Sixth Form: Whirlpool!"

"Water Breathing, Third Form: Flowing Dance!"

"Flame Breathing, First Form: Unknowing Fire!"

The three then cut every single demon down while Tanjiro thought, "Giyu is incredible... From my slight movement, he grasped what technique I was going to use... and then he used one himself, moving to make sure we didn't cut each other. It's freaky!" Giyu had a slightly bored face. Tanjiro thought, "What's that look on his face?" Giyu did a 180 and said, "Let's go." Tanjiro said, "All right!"

Chapter 117: End.
