24 - PAPER AIRPLANES.

It had been several weeks since the trial, Muichiro was on a mission, while Y/N was not. He hadn't seen Tanjito, Zenitsu or Inosuke ever since the first time he visited them at the Butterfly estate, so he decided to see how they're recovering. At first, the young pillar didn't really care about making friends out of these Mizunoto- he already had everything he needed in his life, so the odd trio weren't something he thought of including in it. He did come to realise, though, that these people were actually fun to be around, so he made a mental note to get closer to them. He had been made a bit uncomfortable by Zenitsu very bluntly flirting with him, especially when he was already into someone, but he came to understand that the blonde isn't a bad guy; just a bit desperate. Y/N also remembered of the mental note he made to ask Inosuke to teach him the spacial awareness thing his breathing technique had. He would definitely have to sharpen his senses to achieve that, but it was possible if he were to try hard enough, he could achieve it. He was already capable of sensing other people's/demon's presences and incoming attacks or projectiles, so it should be somewhat easy. He also had to ask Tanjiro about the new breathing technique he used during his fight with the Kizuki and he wanted to apologise for not being able to protect his sister. The odd trio had definitely peaked Y/N's interest, if it weren't for the 3 telling him their ranks, he would've assumed they were ranked Kanoto or something.

Wearing his regular uniform and a pair of zori sandals, Y/N exited the Mist estate. He saw Muichiro out cloudgazing, so he decided to leave younger boy be, leaving the Mist estate territory and running the way to the Butterfly estate. It felt odd running with light shoes, but it was relaxing to feel his feet lighter as he sped through the air. He was also glad he didn't bring any weapons, because it made his body even more relaxed and fast, so he reached the Butterfly mansion in just a few minutes, not even breaking a sweat. It was convenient that the uniforms were so breathable, otherwise the slayers of all ranks would be sweating like pigs 24/7. When he arrived at the gardens of the mansion, he was met with a few workers that were doing the laundry. When he asked about the trio he'd met, the workers told him to go to the training grounds, since they were in rehabilitation training. The moment he entered the familiar room, memories filled his brain and replayed themselves for him, but he put them all to the side to greet the boys who were very clearly struggling with their own training. "Ohayo." He called out, his tone a bit unimpressed with the state of the Mizunoto. Everyone turned around to look at the Cloud pillar. Tanjiro and Zenitsu smiled, Kanao was always smiling, Inosuke's expression was invisible to the eye, since he wore a mask, the butterfly triplets squealed and Aoi waved. "I'm here to help you with training. Nao-chan, Kanzaki-san, the three girls over there, you can take a break." He said, stepping closer to the boys. "We're going to do something a little different." Y/N then proceeded to smirk mischievously, which made at least 2 of the other boys drop their smiles.

"So all we have to do is land a hit on you? That doesn't sound too bad.." Zenitsu commented, but he heard a laugh from beside, coming from Tanjiro, which made him furrow his eyebrows. "What's so funny to you?!" The blonde asked, clearly offended. "It's just that.. There's no way we could ever punch him." The burgundy explained, earning a nod of confirmation from Y/N. "Yeah, I'm kind of here to humiliate you for being slow, to be honest." The pillar admitted, getting up, before Inosuke could protest or boast about his greatness. "Who wants to go first?" The (h/c)ette asked, Tanjiro raised his hand, as if he were in some sort of class. "I'd like to. I've already seen you in action, but I want to put myself to up for a test!" He said, smiling in determination. "Alright. The other two, go sit in a corner or something. Kanzaki, give him 10 minutes to punch me. I will only be dodging." Y/N informed, putting his hands in the pockets of his uniform and backing up from his peer. Tanjiro took a stance, ready to pounce the pillar, but as soon as he marched forward, Y/N disappeared from his sight. Looking around, the other boy was behind him, completely unfazed. The burgundy boy sweat-dropped and marched forward again. This time, Y/N only dodged his kicks and punches with minimal effort, but without disappearing completely. This went on until the 10 minutes had passed. The Mizunoto dropped to his knees and panted when Aoi said the time was up. "Good job, for not getting too sloppy near the end." The Hashira said, patting his friend's head. "Nao-chan, please carry him to some corner while I do this with the next." He said and Kanao did as he asked. "So, who's next?" Y/N asked with a very menacing smile.
