Chương 38: Chapter 11: Toying with Demons.

Zenitsu had carved the runes for SECTUMSEMPRA on the blades of the Hashira, he warned them that the wounds from these blades will never heal, nor will the bleeding stop. Cautioning them to be absolutely careful with their blades because a scratch will make a fatal wound for a human.

The sound Hashira had trailed two upper moon demons in a red-light district. The Sinobu, Rengoku, Giyu and Zenitsu followed Uzui to the red-light district and for Zenitsu it was not difficult to find the demons as their hearts sound different compared to the humans, making them stick out like a sore thumb.

Daki was easily discovered by the evening and Giyu was the one to approach her first, she knew that her cover as Oiran was botched. Daki revealed herself as a demon, priding herself as the upper moon six, Giyu being the no nonsense guy as usual went with his best shot.

"MIZU NO KOKYU~ JUICHI NO KATA—MAIGI" <BREATH OF WATER~ ELEVENTH FORM- CALM.>

The raging water came to a still and Giyu walked towards her in one swift motion and lopped her head off. Zenitsu seeing how easy it was, squinted his eyes and spoke his doubt aloud.

"Was this supposed to be so easy?" Zenitsu asked and raised the flag successfully.

A wild Gyutaro appeared from Daki's body that was throwing a tantrum for being called weak and rambled about her brother and how strong he was with a lot of other bullshit.

Gyuatro did a spectacular job with his entry and Zenitsu made a point to applaud the performance which was replicated by all the Hashira, much to Gyutaro's annoyance. Gyutaro knew that the ones surrounding him were the strongest Demons Slayers, his sister has really fucked up this time around, landing him is a predicament of this scale was nothing to scoff at.

Zenitsu decided to applaud Gyuatro's cool entry and the other Hashira followed him on the matter, much to Gyuatro's annoyance. Zenitsu chuckled and taunted Gyutaro further, "hey, if you were not a demon we could even start with a drama troupe with you playing the cool villain. Such a pity~"

Shinobu had caught on to Zenitsu's intentions and played along, "well, if he decides to be good, you can keep him. I'm quite sure Oyakata-sama would not mind you keeping a weak demon to play with your given performance record."

Uzui caught on and with a shit eating grin plastered on his face he continued, "well, if your drama troupe flops, give him to me. I can make a nice watch dog for my new home."

Zenitsu looked at Gyutaro with a pondering expression, "Uzui-san, choose something else, even if you make him a guard dog, can he even bite properly?"

Uzui chuckled, "HAHAHAHA, don't worry Zenitsu, even if it can't bite, it sure has a talent in barking and showboating. He will be the most flamboyant guard dog."

Gyutaro was feeling rage, pure unsullied rage and indignation. His face turned red and he almost jumped the sound Hashira to bite him. He lowered his head and grumbled, "HOW DARE YOU?" incoherently.

"Well, you have two plans and there is one of him. Just ask him who he wants to follow, consent is a must, always remember that Zenitsu, okay?" Shinobu hammered the last nail in the coffin, Gyutaro jumped at her, rage was clouding his mind and the next instant, he was hacked into pieces before he could even touch a single hair on Shinobu.

Slashing the two heads of Gyutaro and Daki, the demons were killed once and for all.

"Damn this has to be the most flamboyant demon hunt I have ever done." Uzui chuckled.

"Well, I never would have guessed that Zenitsu-chan can be so cunning." Shinobu smiled.

"I have to do justice to the Slytherin name I once bore" Zenitsu chuckled, the others felt confused about the words of Zenitsu.

"Every time we fought demons we were always out numbered and killed, this time ganging up on a demon to hack it apart was way too satisfying. I don't think I can go back to the previous methods, they are not flamboyant enough." Uzui said sheathing his blades.

"Not to forget about the lost formula to make crimson blades that was re-discovered by Zenitsu in the Swordsmith village, this would have been a lot more troublesome otherwise." Rengoku spoke with an approving nod.

"Did you collect the blood?" Giyu spoke for the first time, asking Zenitsu about the blood he was supposed to collect to make a cure for Nezuko.

Zenitsu took out two glass vials with blood from his robes and flashed them under the moonlight before keeping them back.

"So sneaky~ Zenitsu, do you want to be a shinobi? It will do you a lot of benefits." Uzui offered.

"Sure, I would really like to learn about hidden weapons and poisons. Shinobu-san has been stingy about teaching me poisons after the day I teased her about Giyu-san. But, will you really teach me?" Zenitsu asked, smiling widely.

A blade flashed past where Zenitsu's head was a second ago, "Damn, are you really going to kill me just for the little bit of teasing, isn't that too much Shinobu-san?" Zenitsu sweat-dropped.

"Ara~ I just thought there was an annoying fly and slashed it, how did it turn out to be you, Zenitsu-chan?" Shinobu said with a deadpanned expression.

For the first time the other Hashiras thought, that Giyu and Shinobu being together might not be a bad thing. But no one spoke a word, just silently admired Zenitsu for his idiocy.

Zenitsu followed Uzui, who introduced him to his three wives. They were very happy to see their beloved Tengen-sama finally accepting a disciple, for them Zenitsu was a little brother they doted on and teased around.

They taught Zenitsu a lot of things like espionage, infiltration and assassination. The training also had covered a lot on about how to disguise himself and to behave properly to make the disguise perfect.

Zenitsu being an observant person boosted the capacity of his mirror neurons and that let him absorb whatever he was taught like a sponge. During the training, Uzui had found that Zenitsu might appear normal but despite having a sharp brain, his moral compass was in shambles.

He tried to fix it and slowly it worked, but if he were to put it on a scale of one to ten, he would sigh to say that he found his moral scale to be on stage one and he pushed it upwards to stage three after he slowly integrated with the mannerisms he had to master to learn disguise and infiltration.

His training in poison and hidden weapons was completed without a hitch and seeing him performing so and I quote "flamboyantly", Uzui taught Zenitsu the secret footwork art, the SILENT STEPS.

Months passed and his training was coming to an end. Uzui and his wives already considered Zenitsu as a little brother.

Uzui's wives even taught him about grooming, cooking and sewing along with teaching him a lot of their personal recipes and tips and tricks on how to play musical instruments and sing better. With Zenitsu's hearing, the music was a piece of cake for him.

The only lament Uzui had was that Zenitsu was absolutely clueless about the love between a man and a woman, despite Zenitsu having a brutally low score in his EQ department, Uzui left the charming and honey trapping out of the things he taught Zenitsu.
