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

The Cost Of Conquering The Sun

"Good Morning!"

- Tamayo's Letter -
"Tanjiro-san... You provided me with blood from the Twelve Kizuki. Thank you for aiding in my research. The boy that Muzan has turned into a demon in Asakusa has returned to normal. This is thanks to Nezuko-san's blood. He's free from Muzan's control and can live on with just a small amount of blood. The transformation I'm Nezuko-san's blood surprises me. Over this short period, the composition of her blood has repeatedly changed. For some time I have been thinking about why Nezuko-san hasn't returned to her old self and remains in that childish state instead. It could be that something else is taking precedence for her. Something more important than reclaiming herself. Tanjiro-san, this is just a theory, but I think Nezuko-san may soon be able to withstand sunlight."

- Back With Tanjiro -
Tanjiro, who was held up in fear of him dropping to the ground, reached his hands out to Nezuko. Tanjiro says, "Nezuko...! I'm so glad! Are you all right? Are you... human again?" Nezuko answers by tilting her head to the side with a smile while saying, "I... I'm happy. I... I'm fine. I am... Happy!" Tanjiro thought, "She's talking... but her eyes and hands are the same! She still hasn't returned to her human form!" One of the villagers said, "Thank you both for what you did for us! It would have been tragic if Nezuko-Cham had died!" Tanjiro interjects, "No... It really is... great that you didn't get turned to dust!" Tanjiro then pulls Nezuko into a hug and cries out loud. He also said, "I'm so happy! So happy! So happy that you're all right!" Nezuko hugs him back while saying, "Me too!" Genya watches the whole thing from afar with a smile. Genya said, "That's great... Tanjiro... And Nezuko!" Tanjiro finally relaxed and fell to the ground with a smile while thinking, "I'm so glad..."

- With Mitsuri's Battle -
Mitsuri fell to the ground a finally gave up. The Dragon heads chased her as she screams, "Gyahhhh! I can't take it anymore! I'm sorry but this is killing me!" Before the dragon head could eat her, it began to crumble to dust. She was confused and looked toward Zouhakoten's location and also saw him crumbling. She then screams out, "Whew! I'm saved! Tanjiro-kun and the others must've cut the head off from the main body!"

- Elsewhere -
A boy stood in front of a book rack with books fallen to his feet. A lady, along with a maid, entered the room. The lady asks, "Oh dear! What's wrong, Toshikuni? You made quite the mess!" The boy put his hand on his face while saying, "There's finally one who has overcome the sun! Good work, Hantengu!" The lady says, "Well, at least you're having fun! Are you talking about a book you-" She was cut off from having her head struck clean off from her shoulders. Her body fell to the ground and the maid was confused. She asks, "Huh? Ma'am? What happened to your head? What... Huh...?" Toshikuni, who is revealed to be Muzan, had said, "I no longer need to search for the blue spider lily! Mwahaha! It took so long but this is it! This is why... For a thousand years... I've been creating demons, even when I didn't want to!" The maid looks at Muzan in fear while he begins to morph into a new form. He also said, "It's a rare condition that never even appeared in the Twelve Kizuki! The chosen Demon!" Muzan then morphed into his normal body, the original Muzan. The maid was beyond scared as Muzan said, "I can conquer the sun too... If I ingest that girl!" The maid begins to run toward the door while screaming, "Aaah! Murderer! Monster! Monster! Master!" Muzan flicked his arm up and destroyed the entirety of the maid's upper body.

- Storytime -
The one who turned Muzan Kibutsuji into a demon was a physician in the Heian Period. Muzan was going to die before he turned 20. The physician worked hard to give him a little longer to live... But even so, Muzan flew into a rage over his worsening condition... And killed him. However, he discovered that the doctor's medicine was having an effect... Because a change occurred at the moment of the murder. Muzan gained incredible strength... But there was a problem. He could no longer walk under the sun... and he somehow knew he would perish if he was struck by light. Muzan craved human flesh... And didn't mind solving that my eating people. But the humiliation of having activities curtailed during the day infuriated him. He desired a body that would not die in the sun. He examined the physician's medicinal formula, but it was still in the testing stage. Muzan did not know how to make the medicine known as Blue Spider Lily. It seemed to require an actual Blue Spider Lily flower... but he didn't know where it grew nor how to cultivate it. That information had died with the doctor he killed.  No matter where he searched in Japan, it was nowhere to be found. Muzan became obsessed with his research for the Blue Spider Lily that granted immortality... and the ability to withstand the rays of the sun.

- With Muzan -
Muzan thought, "Now that Nezuko has conquered the sun... I foresee a massive battle... With her at its centre."

- With Tanjiro and The Others -
Muichiro asks, "Are you all right, Tanjiro?" Tanjiro says, "Yeah, I'm all right. I'm just glad you're okay. And thanks for the sword, Tokito-kun." Muichiro smiles and says, "Thank you too. Thanks to you, I was able to get back something important." Tanjiro said, "Huh? No... I didn't do anything." Muichiro then asks, "But how is Nezuko?" Tanjiro answers with a laugh and says, "Well, about that..." Mitsuri's yells were heard down in the forest. Then it became more clear what she was saying. She said, "Hey, everybody! Hey! Guys!" She then went and hugged everyone while yelling, "Yaha! We did it! We won! Isn't that awesome?! We all won together! And we're alive! I'm so glad!" Nezuko also said, "Yes! Me too!"

Chapter 106: End.

- A Little Secret -
