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

Upper Moon 3

Tanjiro closely looked at the demon and widened his eyes.

-3rd Person POV-
The demon was an Upper Moon demon.

Upper Moon 3

Tanjiro gasped and thought, "Upper... Three? What's he doing here and now?" The Upper Demon looked at Kyojuro and then at Tanjiro. It destroyed the ground as it launched at Tanjiro first. Tanjiro kicked the Demon's hand while Kyojuro used,

Flame Breathing, Second Form... Rising Scorching Sun!

He cut the Demon's arm off while it backflipped to where he was before. The Demon regenerated his arm and said, "That's a fine sword." Both Kyojuro and Tanjiro thought, "He sure can regenerate fast. This heavy and overwhelming demon aura... So, this is an Upper Rank." Kyojuro said, "I don't understand why you'd go after this boy first." The Demon said, "He could get in the way of the chitchat... of you and me." Kyojuro replied, "What would you and I have to talk about? And besides, this boy fights with me regardless. I'm meeting you for the first time, but I already dislike you." "Is that right? Well, I loathe weak humans, too. The sight of a weakling makes my skin crawl," said the Demon. Kyojuro said, "Then, it looks like our senses of value are completely different." The Demon announces, "All right, then I have a brilliant proposal for you. Why don't you become a demon, too?" Kyojuro declines while the Demon said, "I can tell both you're strength at a glance. You're both Hashira, aren't you? Your fighting spirits have been honed to the hilt. They are close to the realm of the highest." Both Kyojuro and Tanjiro had the same fighting spirits the Demon thought Tanjiro was also a Hashira. Tanjiro thought, "What is he talking about? I'm no Hashira. And what is a fighting spirit?" Kyojuro says, "I'm the Flame Hashira, Rengoku Kyojuro. And this is my Tsuguko, Kamado Tanjiro." The Demon says, "I'm Akaza. Kyojuro... Tanjiro... Let me tell you why you can't enter the realm of the highest. Because you're human. Because you're going to grow old. Because you're going to die. Become a demon, you two. Do that, and you both can train for a hundred, for two hundred years. You can become stronger." Tanjiro thought, "Of all the demons that I've met until now, he has the strongest scent of Kibutsuji! I'm going to fight with Rengoku-san!" Kyojuro explained, "Both growing old and dying are part of the beauty of being an ephemeral creature like a human. The fact that we grow old and die is what makes human life so unbearably precious and noble. 'Strength' isn't a word used to describe just the body. This boy isn't weak! don't insult him. I'll repeat it as many times as it takes. You and I have different senses of value. No matter what the reason, I will not become a demon!" Akaza says, "I see." He flexed his hand and slammed his foot into the ground and formed a giant blue snowflake under him. He uses,

Technique Development... Destructive Death... Compass Needle!

Tanjiro felt his power rise as he started to sweat in fear. They both got ready while Akaza said, "If you refuse to become a demon, I'll just have to kill you both." He lunged at the two as Kyojuro blocked and dodged Akaza's attacks. After a while of battling, Tanjiro saw a small opening and took it. He sliced Akaza's leg and tried to cut his abdomen. Akaza dodged and kicked Tanjiro's sword. Kyojuro and Akaza continued their battle as Akaza said, "There were never any Flames among the Hashira I've killed until now. And no one ever took me up on my offer, either." Tanjiro jumped into the air and used,

Water Breathing, First Form... Water Surface Slash!

Tanjiro and Kyojuro cut Akaza's arms while he regrew them. He focused on Tanjiro and began to throw punches at him. Tanjiro blocked most and was hit in the leg as Kyojuro came from behind and cut Akaza's arm. Tanjiro swept his leg and kicked him high in the air. While in the air, Akaza used,
