The Strongest Slayer: A KNY Fanfiction

Chapter 14: The Red Light District

Takeo, Inosuke, Zenitsu, and Tanjiro all arrived at the butterfly mansion to watch what looked like Tengen Uzui, the sound Hashira of the demon slayer corps with two large swords on his back, kidnapping the butterfly trio and Aoi with Kanao vainly attempting to pull on them. "What's going on here?" Tanjiro asked. "Look, brats. Stay out of my way," Tengen spoke harshly, only for a kunai to plant itself in front of him. "Little brother, why are you doing this?" A familiar voice spoke. "Y-Y/n! Sorry about that! Haha..." Tengen stuttered, staring at the older. "These four aren't even strong enough to be considered slayers... so what in the actual FUCK are you doing?" Y/n asked harshly. "P-Please j-just go..." Tengen stuttered. Y/n chuckled and jumped down, ruffling Tengen's hair. "Don't worry little bro. See you around," Y/n spoke before vanishing, leaving shadows to cling where Y/n once stood. "WOAH! THAT WAS SO COOL!" Inosuke yelled, making Uzui 'tch' in annoyance. "Yeah right... always Y/n getting the attention," Uzui muttered. Takeo grinned. "Y/n taught me how to do some stuff, too!" He exclaimed. "Anyway, let's just get to it. Uzui, let us help you with whatever you needed those girls for," Tanjiro cut in. "Okay, brats! I need help with a mission in the redlight district!" Uzui exclaimed.

With Takeo

Takeo stared at his hands. 'So I have demonic superpowers according to Qrow... and apparently, he has them too... but when can I show anyone?' Takeo wondered to himself, his eyes flashing to the same thing they had turned into when he saved Inosuke from the large demon at mount Natagumo before turning back to their original magenta. Apparently, Y/n's was some form of light energy release, making for a formidable opponent and his was also powerful based on when he sparred with Qrow. Qrow was tricky, having mastered his ability to turn into a crow, making him a difficult opponent to fight. He thought back on all of it, wondering how his friends would treat him. 

Takeo's thoughts no longer being dominant and it going back to Tanjiro

Takeo looked up to see the group moving out. He followed them and they followed along a path until they reached a "Wisteria house." After getting inside and Uzui telling the staff what to do, he began explaining the plan. "Okay. Tallest brat. You travel with me. We'll be looking around and observing for a demon. You three, infiltrate," Tengen told them before going over a more detailed version of the plan.

Two Days Later

After two days, the group learned of the demon's existence when Zenitsu explained how the Oiran, or highest-ranking lady of the house he was assigned to, almost knocked him out with one hit if it weren't for training with Rengoku when suddenly, Tanjiro picked up a smell. "FOLLOW ME!" Tanjiro yelled, making the group turn to him in confusion. Uzui watched as the group ran, though he was impressed by Takeo's running, as it held the traits most ninjas used, involving silence and the readiness to avoid an attack or spring into action, as due to the faint repositioning of his knees. Uzui made note of this development as the group made it to some demon girl about to eat the Oiran that Takeo recognized. "KOINATSU-OIRAN!" Takeo yelled. Tanjiro took in a deep breath. "Total Concentration water breathing, first form improved, dashing water surface slash!" Tanjiro yelled, dashing swiftly and cutting the obi that was eating Koinatsu, flicking his blade of blood before turning. "Hinokami Kagura, solar heat haze," Tanjiro muttered as he turned, his blade flickering and slicing the demon's arm. "AHH!" The demon cried before glaring at Tanjiro, allowing him to see the words indicating the demon's rank as upper moon six. 

"Flame breathing, first form, unforgiving flames," Tanjiro muttered, dashing forward again. It was similar to first form improved, yet the slice was slightly different. The demon, however, managed to raise it's arm. "Hey, you're Warabihime!" Zenitsu exclaimed, making the demon glare. "Ah... the new girl. Though it appears you're a boy," the demon spoke, her tone cool and venomous with no form of remorse or positivity in it. Zenitsu gripped the handle of his blade. It was time to show the group what he learned. "Thunder breathing, second form, Rice Spirit," Zenitsu muttered. After gaining help from Tanjiro to slow his perception, he learned how to do the other forms due to his ability to react properly to his speed. The demon growled and jumped back, her chest slashed. "OOH! OOH! LET ME GO! BEAST BREATHING, FIFTH FANG, CRAZY CUTTING!" Inosuke yelled. Takeo then moved in with his scythe. "My turn. Reaper breathing, first, form, Solitude," Takeo muttered. Reaper breathing was a special form of breathing he uses when in scythe form, with that breathing having seven forms. The first form was a simple slash that went for the eyes and left the user stunned into blindness for a short amount of time. Takeo landed the hit and the demon growled. "GYUTARO HELP ME!" The girl yelled.

A large buff demon with an ugly ass face and two sickles dropped down in front of the group, his sickles made from bone. Tanjiro dashed in, deflecting one of the sickle-blades off of the edge of his katana before grabbing the hilt and swinging under the arm of the large demon named Gyutaro. Tanjiro then twisted and went for the neck, only to get hit in the side, sending him flying. "TANJIRO!" Takeo yelled before racing his scythe, blocking a hit from the obi girl. "Zenitsu! Inosuke! You two get the girl! I'll help out against this mantis!" Takeo yelled before engaging into battle, his scythe fairing well against the sickles. The entire staff portion was made of incredibly pure steel not different from that of the steel that makes the stone Hashira's large ball and ax on a chain. He blocked a hit from the sickle using the base of the scythe before whirling and jabbing the back end inward as Uzui appeared above, slashing down with the explosive power of his blades. Takeo then jumped back and closes his eyes. A rush of emotions hit him as he focused on the strange power that flowed inside of him. His eyes flickered to deep crimson with flecks of gold, though this time purplish lightning flickered along the edges of his eyes, sparking around his eyes as his eyes began glowing. "Let's do this."
