A Cook, A Doctor, A Ghost and A Ronin.

Secret Weapon?

"To find a man to marry! It's good for a girl to find someone stronger than herself! Someone to protect her! You see? Many boys don't understand." Tanjiro is speechless. For that petty reason, she joined Demon Slayer Corps. It's hard for Tanjiro to accept it. 

"Recently, I had an eye with the Voyagers. All of them are very strong! They are reliable and excels us in combat too!" She stated. 

"Kanroji-sama." A female Kakushi interrupts their conversation. 

"You sword will soon be finished being sharpened. Please, come to the workshop for some final adjustments." The Kakushi notify her of her sword is almost ready and ask her to come to the workshop for the final touch.

"Oh my! Looks like I have to go." It looks like she had to go to the workshop. She planned to leave after this.

"Don't worry! I'll see you off." Tanjiro said that he will see her off later when she's done with the final touches on her sword.

"No, I'll probably leave late at night." Kanroji declined. She's going to leave at midnight and she didn't want to trouble the young boy for doing such thing.

"No...But...Really? Hmm..." Tanjiro is a bit saddened. He thought that he could talk more with her. But it seems that time is envious of them both, and Iguro too.

"Tanjiro...I don't know if we'll ever see each other alive again, but let's try our best to do so." They might died on their line of duty. The profession of being a demon slayer is very risky. Kanroji told Tanjiro to do his best.

"You fought an Upper Rank and survived. That's an incredible experience. What you gain through actual experiences is more valuable than anything. It's comparable to five or ten years of training." Kanroji patted Nezuko on her head. 

"Tanjiro, you're much stronger than you were before. Mitsuri Kanroji is rooting for the Kamado siblings!" Kanroji showed her overwhelming support for the siblings. It's true that Tanjiro is getting stronger, but not without the help of Urokodaki or Law.

"Thank you. But I still have a long way to go! Uzui-san and Sanji-san let us win. I'll try harder and harder to beat Muzan Kibutsuji himself!" Kanorji find Tanjiro's determination charming. She adores it.

"You got permission to stay for a long time, right?" She asked Tanjiro.

"Yeah, basically." She crept closer to Tanjiro and put her face beside Tanjiro's ear.

"I hear this village has a weapon that makes you stronger. Look for it, okay?" She whispered. Tanjiro didn't know how to react. He is too flustered by Kanroji.

"See ya!" Kanroji left the place with the Kakushi guiding her to the workshop, leaving Tanjiro with a serious nosebleed.

The Next Morning

Tanjiro is now traversing the woods, trying to find any clue about what Kanroji had just said. Kanroji wasn't someone that's going to lie to him. So the next morning, Tanjiro wake up early to search for any leads about it.

"I wonder what weapon Kanroji was talking about. Maybe a sword? Maybe it's buried or something! This is exciting! Like I'm on a treasure hunt!" Tanjiro is excited to find the treasure. He hoped he could obtained the so-called "secret weapon"

*Sniff*

"This is a really great place, but the smell of hot spring is strong. Hmm...and not being completely healthy is hampering my nose." The smell of hot spring is overpowering his nose. His good nose might had its own advantages, but it doesn't mean that it didn't come with any flaws.

"And I want to find Haganezuka...huh?" Tanjiro spotted two people chatting not too far from him. What are they doing in these woods? 

"A child? And who's that?" From the figure, Tanjiro knew one of it was a kid. Another one seems to be a swordsman. He looks quite familiar.

"Hmm? If I remember correctly, that's a Hashira. What did Shinobu call him again?" Tanjiro remembered the Hashira back in when he first met all of the Hashira and how Law saved his asses but he forgot his name.

"Ah! I remember! His name is Tokito Muichiro, the Mist Hashira!" Now, Tanjiro remembered the young lad's name. Muichiro wears a dark, slightly turquoise-tinted version of the uniform. 

Muichiro's uniform has longer, looser sleeves that are more reminiscent of those of a kimono than of the standard cuffed uniform. Along with this, the lack of bands of cloth wrapped around his calves gives his uniform an overall loose and sizable appearance.

As Tanjiro crept closer and closer, he could hear that both of them are arguing about something. Tanjiro tries his best to not get spotted and remain hidden as he did not understand what was going on. He watched them from the bushes.

"Get out of here! Whatever happens, I won't give you the key! And I definitely won't tell you how to use it!" The boy wearing hyottoko mask shouted. What's wrong? Are they fighting? What should I do? Eavesdropping is rude. But if they're fighting, I should step in. Tanjiro thought to himself.

*Smack!*

Muichiro didn't answer. Instead, he raised his hand and smack the shit out of the little boy without no remorse. His expression is always calm and cold. Of course, this shocks Tanjiro. The boy fall flat on the ground.

*Thud*

Muichiro then yanked the boy buy his collar and shakes the boy, demanding something from him. But the boy didn't seem to answer at all. Tanjiro had enough of this. He directly stormed both of them.

"Stop! What are you doing?!" Tanjiro rushes in, he can't withstand such acts in front of him and stand still. 

"Let go of him!" Tanjiro grabbed Muichiro's arm that is tugging on the little boy's collar. Muichiro do not have any reaction at all. He then stared at Tanjiro with his expressionless eyes.

"You're really noisy. Who are you?" Muichiro found the red-haired very annoying and obnoxiously loud. He really didn't like anyone that gets in his way.

"What are you doing to that child? Let him go immediately!" Tanjiro tries to pull Muichiro's arm away, but he can't do so. He is stunned by Muichiro's strength. I cannot budge him! How?! His arms are thinner and smaller than me! 

"You let go." Muichiro do not want to waste anymore time handling Tanjiro.

*Wham!*
