Sesshomaru: So this is it. 

He grabbed the sword. 

Sesshomaru: Tessaiga, the sword that can destroy 100 demons in one seeing. 

Jaken: I hear that it is forged from your Father's fang! That is to say, the one who holds it in his hands will inherit your father's spiritual power. 

Sesshomaru tried to pull it out, but he burnt himself. 

Sesshomru: Hmm ... there's a seal on it. 

(Y/N): HEY ASSHOLE! 

Inuyasha: WE GOT A SCORE TO SETTLE! 

Sesshomaru: Inuyasha, have you and your friends come here to dig up your own grave? Or is it possible you're here for the Tessaiga? 

(Y/N): That busted-up katana is your Dad's sword? Geez. 

Myouga: HEY! That's Lord Toga's sword you're insulting! 

(Y/N): Inside of this giant ass corpse no less. 

Yang: It would be a massive disap- 

Kagome: NO! NO! DON'T FINISH THAT! 

Yang: Oh poo. Kagome, you just don't have a sense of humor. 

Myouga then noticed the injury on Sesshomaru's hand. 

Myouga: It looks like Sesshomaru hurt himself trying to draw Tessaiga! 

(Y/N): If that's the case, then Inuyasha is the one who is the rightful owner of it! 

Blake: It actually makes sense! If the path to the tomb was entrusted to Inuyasha, then obviously Toga wanted him to have it! 

Inuyasha: I'm not interested in some worn-out old sword! All I want is to settle the score with you, Sesshomaru! 

(Y/N): Geez! Inuyasha, just grab the sword already! If you pulled it out like that, it would totally piss him off! You know, a half-demon ousting a full-blooded demon like him? 

Inuyasha: Oh yeah, that makes sense! 

Weiss: You didn't think that far ahead?! YOU IDIOT! 

Inuyasha: That doesn't prove anything! 

Sesshomaru: I bet you can't even do it. 

Inuyasha: Heh, this is payback time! 

Inuyasha began to pull away and it looked like it was moving! 

But then it stopped. 

Everyone: Huh? 

Inuyasha: ARE YOU SERIOUS?! 

Sesshomaru: Enough of this. It looks like it wasn't meant for you after all. Now perish. TOXIC FLOWER CLAW! 

As he prepared to attack Inuyasha, you redirected the attack! 

(Y/N): Not on your lifetime, asshole! 

Sesshomaru: Damn you! 

Jaken: HANG ON LORD SESHOMARU! I WILL ASSIST Y- 

Ruby: OH NO YOU DON'T! 

Ruby kicked Jaken right into a pile of skulls! 

Jaken: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH! 

He rolled around like a bowling ball and hit a wall hard. 

Jaken: Agh. BURN! I'LL- 

Then Weiss froze him. 

Weiss: ICE MAKE: ICE TIME CAPSULE! 

Jaken: NO! NO! NOOOOOOOOO! 

(Y/N): INUYASHA! 

You pulled out the Tessaiga. 

Inuyasha: WHAT?! HOW DID- 

Sesshomaru: Impossible! How did you pull it out so easily? 

(Y/N): Maybe it recognizes what a hero is and well, I guess Inuyasha was able to move it a bit because he improved. That or maybe your father thought you were a whiny bitch and had no hope of ever succeeding in- 

Sesshomaru: Poison Flower Claw. 

He attacked you, but nothing happened. 

Sehshomaru: What?! 

(Y/N): Yeah, poison doesn't work on me. So- CATCH! 

You threw it to Inuyasha! 

(Y/N): Okay! Let's take this guy down together! 

Inuyasha: You know, I usually don't like having help from others, but in this case, LET'S TAKE THIS FUCKER DOWN! 

Sesshomaru: How daring of you to say that. 

Sesshomaru's eyes glowed red. 

Sesshomaru: Do you really think a human and a half-demon can defeat a full-blooded demon like me?!

He then transformed! 

(Y/N): So, that's your true form? LAME! 

Sesshomaru roared out in rage and tried to hit you, but you dodged easily and- 

(Y/N): SANTORYU: HINOKAMI KAGURA: FAKE RAINBOW TRICHILOCOSM! 

You went through him and delivered a critical wound onto his body! 

Inuyasha: HELL YEAH! NOW EAT SOME OF- 

But the attack bounced off! 

Inuyasha: WHAT?! HOW DID THAT- MYOUGA! 

Myouga: Well Lord Inuyasha, I believe you need to have faith in the sword's spiritual power! Best of luck! 

He hopped off. 

Inuyasha: You got to be kidding me! 

(Y/N): Just do what I'm doing! Simple! 

You dodged another attack, and- 

(Y/N): ITTORYU: FLAME BREATHING: THIRD FORM: LION BLAZING SONG! 

You slashed at one of Sesshomaru's legs, causing him immense pain! 

Girls: YEAH GO (Y/N)! KICK HIS BUTT/ASS! 

Inuyasha: HEY, WHAT ABOUT ME?! 

Ruby: Oh right! Go Inuyasha! Help (Y/N) out! 

Inuyasha: That's not really helping! 

Kagome: Well just believe in your sword! We believe in you! 

Inuyasha: Way to be optimistic. But whatever. I can handle this. 

As he stepped forward, he heard a heartbeat. 

(Y/N): Huh? He seemed to be calm. COME ON INUYASHA! YOU TAKE THE NEXT HIT! 

Inuyasha: Maybe (Y/N) is right. This feels different. So- EAT THIS! 

He managed to cut off Sesshomaru's left arm! 

And then it transformed! 

Tessaiga 

Blake: It transformed?! 

Kagome: That must be Tessaiga's true form! 

(Y/N): NICE! 

Inuyasha: Guess I'm not so useless after all, am I?! 

Sesshomaru roared as- 

(Y/N): LET'S FINISH THIS! 

Inuyasha: RIGHT! 

(Y/N) and Inuyasha: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

You both slashed at Sesshomaru's neck and a massive stream of blood erupted! 

Sesshomaru fleed in pain! 

Jaken had managed to break free from his icy prison at that moment. 

Jaken: LORD SESSHOMARU! WAIT FOR ME! 

He ran off in pursuit of his master! 

Girls: YES! 

(Y/N): WE DID IT! 

Inuyasha: Heh, thanks Father, I guess you really left quite the heirloom. 

You gave him the position of a fist bump. 

Inuyasha: What the? 

(Y/N): Come on, don't leave me hanging, Inuyasha. 

Inuyasha: (sigh) Fine. 

You both fist-bumped. 

Myouga: Yes, well done both of you. Well done. Even I had faith in you all. 

(Y/N): Didn't you hop off? 

Myouga: I didn't want to be in the splash zone obviously. 

(Y/N): Whatever. Come on, let's get back to the village. Everyone hang on. 

Inuyasha and Kagome: Hang on? 

In an instant... 

You used Instant Transmission to get there. 

Kagome and Inuyasha: What the?! How did- 

Team RWBY: Instant Transmission. Very helpful. 

Much later... 

Inuyasha noticed that Tessaiga changed back to its old form. 

Inuyasha: Sheesh, it looks like it changed back. 

(Y/N): Look at Mr. Learning to Care About Humanity. I'm impressed. 

Inuyasha: (blushing) That- Listen here (Y/N), I didn't agree to this because we're friends or anything! I'm going to become a full-fledged demon someday! Why would I waste my time using it to help humans? I mean, yeah Ruby, Weiss, Blake, and Yang are strong and all. But then there's Kagome. All she's good for is for detecting the shards of the Shikon Jewel. But either than that, she's also sloppy at shooting an arrow and- 

(Y/N): Inuyasha. 

Inuyasha: And- She's right behind me, isn't she? 

(Y/N): Yep. 

Kagome: INUYASHA! SIT BOY! 

Inuyasha: Oh crap. AAAAAAAAAAAAAAAAAAAAAAAAAGH! 

(Y/N): Grow up Inuyasha. Grow up.
