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

The Demon Slayer attacks

Kyogai dies with peace knowing just that.

-3rd Person POV-
"Kiyoshi! Teruko!" Tanjiro called out. He reaches the room they are in and slams the door open. "Kiyoshi! Teruko!" He dodges three objects that are thrown at him and asks, "Why are you throwing things?" Kiyoshi apologizes and says, "We're so sorry! The tsuzumi vanished, so we panicked!" Tanjiro says, "I see. Well, I'm glad you're safe." Teruko begins to whimper and cries out loud. Tanjiro walks up to them and says, "You did a good job hanging in there. You, too, Kiyoshi. Come on, let's head outside." He gestures to Kiyoshi onto his back and finishes, "Climb onto my back."
Tanjiro, Kiyoshi and Teruko walk down the hallway in silence. Tanjiro breaks the silence by asking, "Is your leg okay?" Kiyoshi answers, "Yes!" Tanjiro then goes, "You just have to be brave a little longer. I smell Zenitsu and Shoichi. They must be outside. Both of them safe-" Tanjiro was cut off as he caught a scent of blood. "The smell of blood!" He thought as he stopped. Kiyoshi asks, "What's wrong?" Tanjiro answered, "Nothing. Let's hurry!" They begin running to the entrance and he sees the same Demon Slayer from before. Zenitsu looks beat as he protectively holds Nezuko's box. The Demon Slayer keeps delivering kicks while saying, "Take this! Move it! Take this! Draw your sword and fight me! You coward!" Tanjiro gasps softly as he sees what's happening. Basically, on the verge of tears, he hears Zenitsu quietly say, "Tanjiro... I protected it. Because you said... this was more important to you than your life. The thing is..."

-Earlier (Zenitsu's POV)-
"I've always... had really good hearing. Sometimes, I'd know what people had said while I was asleep, and that creeped everyone out. I'm not hearing the sound of the demon. Tanjiro, you defeated that demon, didn't you? I can hear you guys and these strange, loud footsteps.
Shoichi-kun screams, "...itsu! Zenitsu! Zenitsu!" I open my eyes to see both Shoichi-kun and the sky. "Thank goodness! Are you all right?" He asked. I sit up while he continues, "When the room changed, we got thrown outside. We fell from the second-floor window." "Oh... did we now?" I ask while rubbing my head. Shoichi-kin nodded and said, "You protected me, so I'm fine. But..." "I'm glad to hear that. So, tell me, why all the tears?" I look at my hand and see blood. "Now I get it! I fell right into my head, didn't it? Am I gonna... Am I gonna die?" I ask. I groan dramatically and say, "My head is starting to spin." As I finish, I hear a laugh come from inside the mansion. I ask, "What's this? What's this? What's this? What's this? What's this?" The same husky-voiced monster boar yelled, "Comin' through! Comin' through!" It bursts out of the mansion while I cling onto Shoichi-kun, protecting him. "There it is again! The monster boar!" I screamed. It laughed and says, "I'm sensing a demon!" I realize who that is and say, "It's him! I remember his voice! He's the fifth survivor! During Final Selection, he was the first to rush up the mountain, and then, he descended the mountain before anyone else! Mr. Impatient!" The Demon Slayer then looked at the box and laughs, "I've found it!" He ran towards the box while I block him, saying, "Cut it out!" "Who the hell are you? Get out of the way!" He asks. "I'm Zenitsu Agatsuma! I'm with the Demon Slayer Corps like you!" "Uh... Demon Slayer Corps? Then I shouldn't have to tell you! We gotta get rid of that thing! Now, get the hell out of my way!" He spoke. "I'm not moving! This is Tanjiro's-" I spoke. "Don't argue with me! In that case, I'll demolish him and the box together!" He threatened as he nearly cut me with his sword. "I said move it! Why you..." "I won't... I won't let you touch this! It's important to Tanjiro!" I yelled back. "Oh, hey, come on! What are you talking about? There's a demon inside that box! Don't you know? I've known that from the very start!

-Back to the Present (Tanjiro's POV)-
(I'm not writing all that. Mainly because I'm lazy.)
The Demon Slayer continues to kick Zenitsu. While he kicks Zenitsu he says, "After all that bluster, you won't even draw your sword? If you're a fellow Demon Slayer, let's see you fight!" I get a glimpse of my family's gruesome scene from 2 years ago. I start to boil with anger while he continues, "If you're not gonna fight, get the hell out of my way!" Zenitsu continues to take hits from the Demon Slayer while I stand there pushing my anger down. "Move it!" He said as he kicked his face. "Enough!" He says as he draws his blade, ready to stab Zenitsu. "If you won't get out of my way, I'll just have to skewer you along with that box!" He says as he lifts his blade in the sky. I finally yell, "Stop!" The Demon Slayer looks at me in confusion. I lunge at him leaving behind a dust trail. I yell, "Stop this!" As I get closer and closer.

Chapter 27: End.

I cut this chapter short because I got lazy and didn't want to write about Zenitsu's hearing ability.

-A Little Secret-
Tanjiro's hair never grew since the day he was born.
