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

Hashira Training

"Wait until we defeat Muzan, then I'll give you my honest answer."

- About 45 minutes later -
Tanjiro thought about what he said, "It seems Tsuyuri-san didn't like my answer at all. After I said that, she just walked off with the scent of anger and sadness." But Kanao knew that she would probably never get her answer. Finally, Haganezuka arrives with Tanjiro's new sword. Tanjiro beamed, "Haganezuka-san! Your wounds are healed?! Good!" Haganezuka just stood there while breathing heavily. Tanjiro asks, "No? You aren't all right?!" Haganezuka whipped out Tanjiro's sword and gave it to him. Tanjiro took the sword while saying, "Oh...! A katana! Thanks!" Tanjiro examined the new blade while offering him a seat as well. After a while, Haganezuka stuttered, "B... Bl... Bla... The blade? Let me look." Tanjiro unsheathed the katana and saw the black along with a wavy pattern of white at the blade's edge. Tanjiro said, "Whoa...! Incredible! The black is deeper!" Haganezuka explained, "The steel and quality are good... So the former bearer must have been a strong swordsman." Tanjiro examined the blade further and read, "The kanji for 'slay'..." Haganezuka continued, "The swordsmith who forged this katana... Made it for destroying all demons. He didn't engrave his name or anything else... Just that single character. The ranking system began later... And only the Hashira received swords engraved with 'Akkimessatsu' (A/N: Pretty sure that means 'Demon Slayer' or something among the lines)." Tanjiro asks, "Really? What an incredible weapon. But when I used this during the fight... I didn't see that character on it." Haganezuka was quiet before getting angry and saying, "That's because it had only been polished to the first stage. But you guys took it and used it! It was still a little rusty! I wanted to kill you!" Tanjiro apologized while Haganezuka continues, "Even now that pain hasn't fully healed. That's why I've been weeping! Oh, the pain! It's unbearable! I was interrupted so many times while sharpening it, that I had to start all over again. I'll like you!" Haganezuka grabs Tanjiro's hair whilst yelling, "Listen, Tanjiro! Now you owe me a lifetime supply of Mitarashi Dango (Dumplings)! You got that?" Tanjiro yelled, "Ow! Ow! Ow! You're poking my check! R-Right I got it!" Haganezuka storms off while saying, "Thank you very much!" Tanjiro says, "Get well soon!" Tanjiro sheathed his new katana and thought, "Back to training it is. I need to master this technique before I head into another battle because it's really draining after a while." He powers up again and continues with his training. After a few hundred rushed pushups, Inosuke came to Tanjiro while yelling, "Stronger! Stronger! Stronger! Group strength training starts now! They said something about strong guys gathering for lessons or something!" Tanjiro gets up and asks, "What's that about?" Inosuke folds his arms, and while acting proud, he says, "I don't know!" Tanjiro adopted the pushup position and asked Inosuke if he'd like to join him.

- Couple Hours Later -
"The special training began. It was called Hashira Training. Those ranked lower than Hashira trained with them, one after the other. Hashira usually didn't train anyone but their Tsuguko protégées... Simply because they were too busy. In addition to providing security for large regions, the Hashira had many other responsibilities, including gathering information on demons and training to further improve their own skills. However, after Nezuko conquered the sun... Demon appearances stopped completely. It was like a calm before a storm, but as a result... The Hashira could do their security activities at night and focus on training during the day," said Zenitsu. Tanjiro, who had trouble absorbing most of the information, said, "Really? That's amazing!" Zenitsu's face looked strained while saying, "It's not amazing at all! It's awful! It's hell! Who thought up such a thing?! They should just die!" Tanjiro yells, "Hey! Sparring with someone ranked higher than you is a quick way to improve! When you face a stronger opponent, you absorb it and get stronger yourself!" Zenitsu bit Tanjiro's forehead while saying, "If you like the idea so much then you and I are no longer friends as of right now! It's okay for you! You're really strong it's almost a breeze for you! We have to go train now! Let's go!" Tanjiro was being dragged by Zenitsu and thought, "But what happened to not being friends anymore?" Tanjiro was immediately pecked in the head by his crow. Tanjiro covered his head in pain while Zenitsu watched with wide eyes. Tanjiro asks, "What did you do that for? That's mean!" The crow caws, "A letter from the Master! Read it right away!" Tanjiro asks, "A letter? For me?! He went through all that trouble? Wow...! I wonder what it is?"

Hashira training
Begins with gruelling basic physical fitness workouts with Tengen. Followed by lessons with Mitsuri Kanroji in hellish flexibility and Muichiro Tokito in high-speed movement. Next comes swordsmanship with the Serpent Hashira... then lessons intraining mental spirits and confidence with Kyojuro Rengoku and learning to make infinite strikes with the Wind Hashira and finally strength training with the Stone Hashira. Sparring with Corps members one after another for hours on end should further improve the Hashiras' strength as well. If this raises the heart rate and body temperature, making it possible to manifest the mark, that would also be ideal. Those who have the mark train to maintain their mark condition. And immediately sharing what's been learned among all the Corps members raises the overall strength of the Corps itself... In preparation for the coming fight. Except for one man.

- At Giyu's Estate -
Giyu sat inside his estate whole Tanjiro says, "Excuse me... Tomioka-san? Hello there...! Pardon me...! Giyu! It's me... Tanjiro Kamado! Hello...? Well... I'm coming in!" Giyu thought, "Coming in...? No! He must mean he's leaving. I must have misheard." The door slid open with Tanjiro's smiling face popping in. Tanjiro enters and greets the lonely Water Hashira. Tanjiro then talked about how they trained at each Hashira location. Tanjiro then sat right in front of Giyu while saying, "Anyway, that's how we're all training!" Giyu said and thought, "I know." "He's so close!" Tanjiro says, "Oh! You knew? Good! Right now, I'm at Kanroji-san's but her flexibility training is a little hard. But will you give me lessons?" Giyu then declined which causes Tanjiro to ask, "Why not? You smell a little angry... What are you mad about?" Giyu explains, "I'm angry that you didn't fully master Water Breathing. You were supposed to become the Water Hashira." Tanjiro rubs his neck while saying, "I'm sorry about that. But I talked to Urokodaki-san. He said that it isn't unusual to change the breathing you use or to give birth to a new style. And that Water Breathing techniques are especially close to the basics, so they give rise to many new styles." Giyu said, "Don't say that. There's currently no water Hashira! Someone must fill that role as soon as possible." Tanjiro was confused and asked, "There's no water Hashira? What about you, Giyu?" Giyu says, "I'm not the water Hashira." He stood up and walked away while saying, "Now go." Tanjiro thought about the letter Kaguya gave him.

- Kaguya Ubuyashiki's Letter -
"Tanjiro... How are your injuries? Unfortunately, I'm unable to move. I want to speak with Giyu... But... I don't think I can. This is an incredibly important time. We must all come together and do our best. Would you please talk to Giyu? He always turns his back and goes alone. Help him face forward. Will you be persistent when you talk to him?"

- Back With Tanjiro -
Tanjiro then yelled, "I will!"
After that, Tanjiro followed and hung around with Giyu all night and day while talking all the time. Tanjiro talked nonstop. Giyu was perplexed. Would this go on for the rest of his life? If he spoke to Tanjiro, then would the boy leave him alone?

- Four Days Later -
Giyu finally gave in. Giyu then said, "I haven't passed Final Selection." Tanjiro asks, "Huh? Final Selection? At the mountain with wisteria flowers?" Giyu then explained, "That's right. That year... There was a boy like me who had lost his family to demons. His name was Sabito. He had flesh-coloured hair. We took Final Selection together." Tanjiro instantly remembered the two people who trained with him during his time training with Sakonji. Giyu then continues, "We were both thirteen years old. The same age and alone, we quickly bonded. Sabito had a strong sense of justice. He was also the one to die in Final Selection that year. He killed all the demons on that mountain almost single-handedly... And get everyone passed but him. I was injured by the first demon that attacked and I fell into a daze. Sabito came to my aid. He entrusted me to another boy... And left in the direction of voices calling for help. The next thing I knew, Final Selection was over. I had somehow survived the seven days of Final Selection and passed, but... Can you really say that someone who hadn't defeated a demon and had to be saved by someone else actually 'passed'? I'm not worthy of becoming the water Hashira. I can't stand shoulder to shoulder with the other Hashira. I'm different from them. I don't deserve a place in the Demon Slayer Corps." Giyu turned heel and said, "Have a Hashira give you lessons. That would be best. I won't manifest the mark... Although Sabito might have. Don't bother with me anymore. It's a waste of your time."

Chapter 109: End.

- A Little Secret -
Tanjiro will train with his ultimate technique to master it. He knows he will gain no benefits from it but will still try if he wants to use it without draining his energy.
