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

Final Selection Pt. 1

"By now I'd say I'm more than ready for Final Selection."

-Tanjiro's POV-
The night before Final Selection, Mr. Urokodaki prepared my outfit for tomorrow. He reminds me how demons grow with the more food they eat. He also opened a slider, which revealed a mask. He gave the mask to me, and said, "It's called a 'warding mask'. I've charged it with a spell to protect you from harm." "Warding mask..." I asked as I stared at the mask.

-Time Skip to morning-

I started to get dressed in the outfit I'd use for the Final Selection. After getting dressed, I head towards Nezuko's room, only to find her still sleeping. I walked up to her and said, "Nezuko..." I grabbed her hand and put it worsens my head. "I'm coming back here no matter what, all right?"
Mr. Urokodaki told me, "Don't worry about your sister. I'll take good care of her." I say, "All right! Thank you very much!" I run down the path, and wave back, "I'll be going, then, Mr. Urokodaki!" He reciprocated the action. As I got further down the mountain I yelled, "Tell Sabito and Makomo thanks!"

-Urokodaki's POV (Very brief)-
"Huh? Tanjiro... How do you... know the names of those dead children?"

-Time Skip to Final Selection-

-Tanjiro's POV-
I walk under glowing wisteria trees and admire their beauty, "Wow. Look at all these wisteria flowers. Even though they're out of season..." I walk toward a set of stairs and begin to climb them. As I reach the top, I count roughly about 26 people who have attended. The only attendees that caught my eyes were, a girl with a side ponytail being held by a butterfly hairpin, a yellow-haired boy who seems dirty, and a boy with a scar running across his right ear to his left eye. "There are so many." I talk to myself. "Everyone... we thank you for coming here tonight. To the Demon Slayer Corps Final Selection." Two guides spoke in tandem. The white-haired guide spoke, "There are demons imprisoned here on Mt. Fujikasane, captured alive by the Demon Slayer swordsmen, and unable to leave." The black-haired guide spoke, "That is because wisteria, which demons hate so much, blooms even out of season from the boots to halfway up the mountain." The white-haired guide spoke, "However, there is no wisteria from this point on, and so demons abound." The black-haired guide spoke, "You'll need to survive here for seven days to pass the Final Selection." They spoke in tandem, whilst bowing, "And now, be on your way." I am determined to pass this Final Selection.
As I'm running around the mountain, I think, "Survive for seven days... That's all I'm going to think about." I run to a boulder and crouch beside it, "First, I'm going to survive tonight. Once the sun comes up, the demons won't be able to do anything, so I can get some rest then. So, I'll have to head east! I'm gonna make my way to where the sunlight will hit first!" I mentally tell myself. I notice 2 presences heading my way. I sniff the air and stop. I put my hand on my sword, waiting for a battle. "This smell... It's a demon! And their presence is nearby." I hear rustling everywhere I look. A demon jumps from a shrub and tries to punch where I was. I backflip and notice another presence behind my back. I look back to see a second demon. The demon throws a kick but hits my sword as I block it. I wondered, "Should I use water breathing?" The demon behind me charged toward me, but I found out he was charging at the other demon. "Don't even try to grab my prey, man! Get off my turf, dammit!" The first demon screamed. The other demon fired back, "The hell with you! Just beat it!"
"Two of the right at the get-go? If anything, I can easily take them." I say. "That's my prey, you know! The long-haired demon yelled. "Shut up! It's first-come, first-served!" He screamed. The demons jump up and charge toward me. Block the first demons attack and attack the second one. I take off his arms while twisting my body to the other demon. I was too late as it kicked me away. "These demons attack in great coordination. I'll just have to up my speed if I want to beat them," I thought. "It's been ages since I've eaten human flesh!" The long-haired demon screamed. I take a big breath in and used,

Total Concentration! Water Breathing! 4th Form: Striking Tide!

I mentally say as I see the opening thread. I guide my blades to the thread mark and successfully behead the demons. "I did it! I defeated a demon! I finally defeated a demon!" I said in my mind, while in joy. I'm kinda bummed out that these demons didn't pose a challenge. That's what I get for excessive training. I walk up to the demon's corpses, "When I slash demons with the sword Mr. Urokodaki gave me, not even the bones are left behind, huh?" I also said in my mind.

-A brief memory of Tanjiro's-

"A demon's weak spot is its neck! But you can't kill it with a normal sword even if you slash its neck." Mr. Urokodaki told me. "Then, how can I take it down?" I asked. "The swords wielded by the Demon Slayer Corps... are forged with special steel. That's the only way to kill a demon. They're called the 'Nichirin Swords'.

-Present Time-

I insert my sword back into its scabbard. I put my hands together and say, "Rest in peace." I feel a massive presence. I take a whiff of the air, the smell was horrible. "What's this rotten smell?" I gagged. To my left, A boy's scream can be heard. "No one over tile me! I never signed up for this!" I ask, "What's this?" I feel a massive presence coming from where the boy came from. I am both excited and scared of what it might be. I look toward to see a massive demon. "What the hell is that?" I asked myself.

-Back at the boulder-
"Ne, Sabito... do you think Tanjiro can beat that one?" Makomo asks. Sabito responds, "If Tanjiro doesn't mess this up, then I'm pretty sure we know the answer that, don't you?"

-Back with Tanjiro-
The boy continues to run while panting. He trips and says, What's this morphed demon doing here anyway? They didn't tell us!" The large demon has a body of a dead participant in hand, ready to devour it. It raises the body to its mouth and devours it whole. "He got eaten!" I mentally yelled. After devouring the body whole, the demon's body begins to grow in size while its power just shot up. The participant runs away in fear, as the hand demon reaches toward him. Before the demon's arm could reach the boy, my body moved on its own. I used,

Water breathing, Second Form! Water Wheel!

Chapter 8: End.

I hope you enjoyed this chapter. By the time I wrote this, I was really tired so some parts may be a bit wonky.

-A little secret-
When the hand demon devoured the body, Tanjiro kind of got a start on how big it got, and how its power shot up.
