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

Kaigaku

"I no longer think of you as my senior."

- With Giyu and Kyojuro -
The two were nearing Tanjiro's location with Kyojuro yelling, "Stay sharp, Tomioka! Whatever this place is, it seems to move around while trying to separate us!" The two then heard, "Kaaaw! Deceased!! Kocho Shinobu is dead!! She fought with an Upper-Rank Kizuki and died!!" Both were shocked at the news but Kyojuro thought, "The crow... What's with that paper on its neck? The message came unusually fast."

- Elsewhere -
A black-haired boy, along with two white-haired girls sat inside an estate while drawing maps of Muzan's infinity fortress. The black-haired boy said, "Shinobu is dead. The other Hashira are still alive. Is Shinobu the only one to confront an Upper-Rank Kizuki?" A white-haired girl said, "No." The boy asks, "Have the crows that borrowed Yushiro's eyes reached half of them yet?" The other white-haired girl said, "Not yet." That boy was named Kiriya Ubuyashiki. His eight and is the current lord of house Ubuyashiki. He is the eldest son of the Ubuyashiki family. Despite losing their father, mother and two older sisters...he does not mourn. In these circumstances, he does not even have time to shed tears. It is the same for his two younger sisters. The one to his left is named Kuina and the one to his right is Kanata. His older sisters' names were Hinaki and Nichika. Like their mother, neither ever left their father's side. Their father was strict. He would not live long, so he had to quickly raise his children into adulthood. Their similarly strict mother was kind but she is also gone. So Kiriya must take his father's place and become a father to the child warriors of the Demon Slayer Corps. Kiriya said, "We have little information. Order the crows to spread as many of the eyes as possible." Kanata said, "Understood." He points to a location on his map and said, "Muzan's location hasn't changed. At present, everyone is far away. Lead them north. The ones confronting the Kizuki are... I see... Tanjiro and Kanao but Rengoku and Tomioka have yet to catch up to them." Kanata adds, "Agatsuma has now encountered Upper-Rank Six."

- With Zenitsu -
Kaigaku said, "You haven't changed. You're still a shabby...little runt. Have you become a Hashira? Huh? Hey, Zenitsu. Can you use anything besides the first form?" Zenitsu tilts his head and said, "You seem thrilled to have reached the very bottom of the Upper Ranks through merely filling in blank positions." Kaigaku laughs, "Oh... You can talk back now, huh?" Zenitsu asks, "Why did you become a demon?" Kaigaku says, "You..." Zenitsu cuts him off by saying, "Why should someone poised to acquire Thunder Breathing become a demon? Ojii-san (Grandpa) killed himself...because you became a demon!!! Ojii-san...died all alone! There was no second! When you commit seppuku, someone has to cut off your head...or you suffer in agony before you die! Jii-chan could have made it quick by cutting his throat, but he didn't! Because the fielder of Thunder Breathing...had produced a demon!!" Kaigaku yells, "I don't care! So what? Are you saying I should be sad? That I should repent? I don't care about anyone who doesn't value me! At every moment...I always...serve those who know my value! If the old man is dead, fine! I did everything I could, but he wouldn't make me his successor! The old bastard said he would make me a joint successor with scum like you. He may have been a former Hashira, but I have no use for a senile old man!" Zenitsu starts to laugh at Kaigaku but then says, "Ojii-san wasn't senile. If I'm scum, then you're trash! I feel sorry for Ojii-san because he had such pathetic successors... I can only do the first form and you can do everything else except that!" Kaigaku reaches for his sword on his back and yells, "Don't lump me in with you!!!" Kaigaku uses,

"Thunder Breathing, Fourth Form: Distant Thunder!"

Blackish and yellowish electricity engulfed the area around Kaigaku while Zenitsu calmly reaches for his blade. He then dashes forward behind Kaigaku, who tried to slash Zenitsu. Zenitsu looks behind him and coldly says, "You're too slow... You scum." Kaigaku's neck spurted blood out with him reaching to cover it. He thought, "He cut me!! He's fast!! He moves like a completely different person!!"
