Recap.

Yahaba closed his hand eyes and a bunch of arrows came at them.

Y/n: Wind Breathing, First Form: Dust Whirlwind Cutter.

Y/n made his sky blue whirlwind which consumed the arrows.

Y/n: Now, use the Sixth Form, Tanjiro.

Tanjiro understood and he used Whirlpool to consume the arrows and Y/n's whirlwind which made the whirlpool go faster.

Y/n: Now, use the footwork of the Third Form.

Tanjiro used his footwork to completely change the arrows course.

Tanjiro: Twisting Whirlpool, Flowing Water!

Yahaba used more arrows which got caught up in Tanjiro's Whirlpool whirlwind.

Tanjiro: My sword is heavy!

Y/n: Use that weight to cut that son of a bitch's head off.

Tanjiro: Second Form, Improved: Lateral Water Wheel!

Tanjiro slashed Yahaba's neck vertically and cut his head off.

Tanjiro fell after he successfully killed Yahaba.

Tanjiro: We did it, Y/n. You knew the Whirlpool wouldn't be as strong without it being underwater, but you used your whirlwind to speed it up and this demon's attack added power.

Yahaba's head fell in front of Tanjiro.

Yahaba: You damn brats! How could you do this to me?!

Y/n: If you were smart, you wouldn't have came here. There's no way you or your partner are members of the Twelve Kizuki. Not when your both this weak.

Yahaba: I just needed to bring him your head and you, that's all it would've taken to finally win his approval! I'll never forgive either of you for what you've done! I'll make sure you both pay for what you've done to me! My face is filthy because of you two shoving it into the dirt!

Y/n: I wish I slashed your jaw before Tanjiro cut your head off.

Yahaba: I swear I'll kill your friend and leave you in bad enough condition that Susamaru will easily be able to bring you back to him.

He showed his eyes, the one that was looking at Tanjiro had arrows in all directions and the one looking at Y/n was had up and down arrows. Yahaba closed his eyes and sent Tanjiro flying back and Y/n was sent flying.

Y/n: At worse, all this will do is break both of my legs. Shouldn't be too bad.

Y/n flew down hard and as he predicted, both his legs broke.

Y/n: Well, this is a bitch.

He saw Tanjiro use Water Breathing moves to stop his body from getting crushed.

Yahaba: You haven't suffered enough. I'm not done, not just yet. Your pain will be excruciating.

Tanjiro was still desperately trying to survive.

Y/n: Okay, this where I step in.

Y/n's legs healed and he started to walk towards Yahaba's head.

Yahaba: Still not enough. Not ye-

Y/n stepped on his head and it finished disintegrating.

Y/n: Oh, be quite.

Tanjiro fell down.

Y/n: Tanjiro, you okay?

Tanjiro: I'm fine, but I cracked my rib and broke my leg. We need to help the others.

Y/n walked over to Tanjiro and placed Tanjiro's arm around him.

Tanjiro: You don't have to do this, Y/n. I'm the oldest son!

Y/n: If you crawl, you won't make it.

Back with the fight against Susamaru.

She started to use her temari to draw up a dust cloud which covered her as she threw her temari at Yushiro who easily dodged them.

Yushiro: What a fool! Avoiding a bunch of linear attacks like these is child's play! Finding you will be easy, too!

He turned invisible and went in, but Susamaru used the dust to track Yushiro and she threw a temari at him which Nezuko deflected with her regenerated foot.

Susamaru: Now's when the real fun starts.

Yushiro: Don't do that! You can't be reckless just because you're immortal!

Nezuko just stared at him.

Yushiro: What is it?

Nezuko patted his head.

Yushiro: What are you doing?! Watch out!

Susamaru threw a temari but...

???: Claws-Purifying Wind.

The temari got split in half from a slash that came from Y/n.

Y/n: Nezuko, take Tanjiro inside. He's hurt.

Nezuko nodded and took Tanjiro inside.

Yushiro: You're fashionably late.

Tamayo: I take it you defeated the arrow demon.

Y/n: Yeah. Do me a favor.

He took off his mask and gave it to her.

Y/n: I really like this mask, keep it safe for me.

Tamayo: Okay.

Y/n: Thank you. Now, to get serious.

Susamaru: This will be fun!

Y/n: Make a note of this now, you six armed bitch. I know you aren't a member the Twelve Kizuki.

Susamaru: What makes you say that?!

Y/n: When I was about to cut your head off, I got a good look at your eyes.

Susamaru: So?

Y/n: So, if you really were one of the Twelve Kizuki, your rank would be engraved in your eyeball. You however don't.

Susamaru: Aren't you the smart one? No matter. I'll still bring you to him. Then maybe he will make me a Twelve Kizuki and I just might also get a mark!

Y/n: Mark?

Tamayo: This is the first I've heard of it.

Susamaru: That's because his top researcher came after you left, Fugitive. This demon gives a special mark to demons he thinks are worthy of its power! His name is, B/n L/n.

Y/n's eyes widened when he heard that name.

Susamaru: Enough stalling, let the game continue!

She threw a temari at Y/n who didn't even react and his left arm got blown off for Nezuko to come back and see.

Nezuko: Hmmm!

Susamaru: Come on, at least fight back.

Y/n still wasn't responding.

Susamaru: What's wrong? Are you scared of B/n? Did he do something to you? Whatever it was, you probably deserved it!

She started laughing and Y/n started speaking in a weird language (up to you what it sounds like.)

Y/n: (Translation: Piece of crap.)

Susamaru: What was that?

Y/n's arm regenerated in a single second to Susamaru's shock.

Y/n: (Translation: Know your place.)

A tornado formed around him to everyone's shock and when it cleared, Y/n looked different. Both his eyes became yellow, his skin and hair turned white, two gaint white wings grew from his back and he grew a beak from his forehead.

Susamaru: (Thinking: When did he start looking like that? Wait, never mind that. He's so much stronger!)

Y/n: (Translation: I'll pay you back for this pain.) With cutting wind!

A gaint wind vortex appeared behind him.

Tamayo: We need to get to the basement, now!

They all rushed inside and Y/n finished charging his attack.

Y/n: Blood Demon Art: Cutting Wind Vortex!

He launched the wind at Susamaru who tried to counter with her temari, but they were cut into pieces and when it hit Susamaru, her body started to get chopped into pieces. As Susamaru heavily fell to the ground and screamed in agony, Y/n walked to her.

Y/n: (Translation: What's wrong? Weren't you really talkative? I guess your words are silenced by your screams. Why don't you use your temari to defend yourself? That is, if you can even move.)

He started to cackle savagely and the vortex eventually stopped along with Y/n returning to his original form.

Y/n: That was fun.

He looked at Susamaru who was now a chopped up piece of flesh.

Y/n: Even though you survived, there's no way you'll be able to regenerate before the sunrises.

He walked inside and eventually got to the basement where everyone was waiting for him.

Tanjiro: Y/n.

Y/n: Tanjiro-

He tripped and fell to his knees.

Tanjiro: Are you okay?

Y/n: My cells hurt.

Nezuko hugged his head but he was in too much pain to even care.

Yushiro: What the hell was that?

Tamayo: How did you get such power in such a short amount of time.

Y/n: I don't know, I've never done that until now.

Nezuko let go of Y/n and hugged Tamayo to Yushiro's annoyance.

Yushiro: What are you doing?! Step away from Lady Tamayo! That's so rude!

Y/n: Shut up. I might be in an ocean of pain, but I can still kick your ass, you fathead suck up.

Tamayo: It's okay, Yushiro. I don't mind at all.

Yushiro: Right.

Y/n: Way to prove my point.

Nezuko patted Yushiro's head for him to be annoyed.

Tamayo: It's a bit strange. She's been acting like this ever since she woke up. I wonder if she's all right.

Tanjiro: There's nothing to worry about. She's just fine.

Y/n: Yeah, this is just classic Nezuko.

Tanjiro: If I were to make a guess, I say she thinks of you both as family.

Tamayo: Us as family? But wait, I thought the spell Nezuko was under only made her see humans as family. And Yushiro and I are demons.

Tanjiro: Not to Nezuko. You two are as human to anyone to her. She wanted to protect you. You know, I didn't like the idea of that spell at first, but she seems to still have a will of her own so-

Tamayo broke into tears.

Tanjiro: I'm so sorry! Nezuko, stop it, get away from her! You're being very rude!

Y/n: Will you shut it, Tanjiro? Those are happy tears on Tamayo's face.

Tamayo hugged Nezuko back.

Tamayo: Thank you. Thank you so much, Nezuko.

Y/n got a vision of a beautiful woman with long black hair, but her upper face wasn't visible.

Y/n: (Thinking: Who was that?)

Tamayo: Yushiro and I will be leaving this region. We're too close to Kibutsuji now. It's far too risky to stay here, we need a new place to hide. Besides, I think I've hidden my identity, but after treating so many humans, I'm sure some of them figured out I'm a demon. Children and the elderly are especially perceptive. So, Tanjiro and Y/n.

Tanjiro/Y/n: Yes?

Tamayo: To protect Nezuko, would you like us to take her with us when we go.

Yushiro Tanjiro and Y/n were taken aback.

Tamayo: Obviously, I can't promise her safety, but I believe she'll face less danger than she will in battle.

Tanjiro: (Thinking: She might be right. With them. Wherever they end up, Nezuko would be safer.)

Y/n: (Thinking: I want Nezuko to be safe, but I don't want her to leave us.)

Nezuko took both their hands and they both smiled in response.

Tanjiro: Miss Tamayo, thank you for your concern. But... Nezuko's staying with us. Nothings gonna break me and her apart.

Y/n: Plus, I trust Tanjiro better to protect her since I have known him longer than I've known you.

Tanjiro: And I trust Y/n to help.

Tamayo: Yes, I understand. Well, I wish you good fortune then.

Yushiro: All right, we will be leaving as soon as we cover our tracks. You should get moving as well.

Tanjiro: You're right. And good luck. Thank you for everything you've done for us. Let's go.

Y/n: I think I might need help.

Nezuko helped Y/n up the stairs.

Yushiro: Tanjiro!

Tanjiro looked at Yushiro.

Yushiro: Your little sister, I guess she is a beauty.

Tamayo: Oh, before you go.

She gave Tanjiro Y/n's mask.

Tamayo: Give this back to Y/n, he said it was special to him.

Tanjiro: Thank you.

Later.

Tanjiro and Y/n were on the move again and getting pestered by their birds.

Crow: South-southeast! South-southeast! South-southeast! The next place you two need to go is south-southeast!

Hawk: Would you shut up, douchbag?!

Y/n: Yeah, we heard you the first sixteen times.

???: Please!

They looked ahead and saw Zenitsu who was now wearing his yellow white triangle haori over a Demon Slayer Corps uniform bowing to a young girl.

Zenitsu: Please! Please! Please! Merry me! You know, I could die any day now! Marry me so I don't die alone! Merry me, I'm begging you! Please!

Tanjiro: Wh-What is he doing? What on earth?

Meanwhile.

Back in Asakusa.

A tall man with white hair with a really small ponytail, a forehead protector, red eyes a no sleeve Demon Slayer uniform, showing of his huge muscles, and two big swords on his back looking at Asakusa from a high place.

Tall guy: Nothing.

He jumped down to a guy with flame hair, big yellow eyes, and white haori with flames engraved on the bottom of it and a Demon Slayer uniform who was eating udon at Toyo's cart.

Tall guy: Are you sure this where he was? From what I taught him, he should now better than to go to some mediocre town.

Flame guy: I'm positive. (Eats some udon.) Tastey!

Tall guy: Are you seriously eating at a time like this, Rengoku?

Rengoku: I couldn't pass up such an amazing bowl of Sanuki udon, Uzui.

Toyo: Oh, it seems you have similar taste to another udon lover.

Uzui: Uh-huh. Did you by chance see what he looked like?

Toyo: He had short H/c hair, pale skin, a white haori with the word wind on it, a white bird mask and he wore clothes just like yours. Why? You know him or something.

Uzui: No. Come on, Rengoku.

Rengoku finished the udon.

Rengoku: Tastey!

They walked off.

Uzui: At least we have a lead. When I find that kid, I'll paint the path I meet him on with his own blood. In a flashei way, of course.

Rengoku: Uzui, I am also crossed with Y/n, but master said to bring him back alive.

Uzui: I know. Let's just hope master sees a good punishment for him.

Preview.

Tanjiro: South-southeast! South-southeast! I mean, we just finished fighting. Can't we get some rest?!

Y/n: If you want to cure Nezuko, you need to toughen up, Tanjiro.

Tanjiro: I guess it was a pretty good impression. And we saw a side of Y/n even he didn't know was there.

Y/n: I'm glad you at least enjoyed seeing it. It did put quite the toll on me.

Tanjiro: Now, it's time for another Taisho-era secret! The Kasugai Crows that deliver our messages all have names. I heard that my crows name is Matsuemon Tennoji.

Y/n: And my is named Hatake.

Nezuko muffled something.

Y/n: You want me to do an impression of Hatake? Okay. (Impression: I'll claw at you if you miss the next Chapter!)

Tanjiro: That's right, we haven't stopped fighting since the start.

Y/n: You should have seen how tireless my former master was, he would kill demons even before he found out about the Corps.

Tanjiro: Next, Chapter 11, "Tsuzmi Mansion"! Guess we better get back to work.

Y/n: Let's go.

To Be Continued.
