(Timeskip to the city of Asakusa)

Now we see the same black and red hedgehog wearing armour walking through the town while everybody was looking at him and muttering to each other.

Citizen 1: It's the blur

Citizen 2: But he's look different

Citizen 3: Why he's wearing armour and a sword?

Then he hearing them muttering about a blue blur in this city.

Black hedgehog:*thought* Hmm, so they know about Y/n, looks like I got find him

Then he dashed in a yellow blur making everyone surprised about this.

Citizen 4:*surprised* HE ANOTHER BLUR

Citizen 5:*surprised* I CAN BELIEVE IT

Meanwhile he was dashing through the city in a blur and he was thinking about Y/n.

Black hedgehog:*thought* I wonder how he looks like now? I better find him

(Timeskip)

We now see Hibari and Y/n coming to Kiriya classroom when they got there they see Asuka, Katsuragi, Yagyu, and Ikagura there.

Yagyu: Hey Hibari

Katsuragi: Hey there Hibari

Then out of nowhere a smoke bomb came and explode making everybody coughing and it revealed was Kiriya in the class.

Kiriya: Good morning everyone

All: Good morning Kiriya-sensei

Kiriya: I have something to announce

Y/n: What is it?

Asuka: I wonder what could it be?

Kiriya: There are some Yoma readings in the city of Asakusa

Kiriya: Want y'all to split into two because there are six of y'all, Asuka and Hibari I want y'all to go to the downtown of Asakusa, Yagyu and Katsuragi I want y'all to go to the uptown of Asakusa, and Y/n and Ikagura I want y'all to go to the center of town

All: Yes sensei

The girls then pull their scrolls between their breast and Y/n then pull his scroll out of one of his quills.

All: SHINOBI TRANSFORMATION!

(Timeskip with Hibari and Asuka)

Now we see Asuka and Hibari in their Shinobi form jumping on buildings to buildings looking for the yoma and Hibari then ask Asuka something.

Hibari: Um, Asuka?

Asuka: Yes Hibari?

Hibari: Do you like Y/n?

And Asuka started to blush and she said while stuttering.

Asuka:*blushing* W-what d-do y-you mean?

Hibari: When Katsuragi say that to me and Yagyu did you have 'fun' with Y/n and you and Y/n started to blush, so what that means?

Then she was starting to get redder than Y/n's shoes and her scarf together and she was about to said something but there's was strange noise.

???:*ROARS!*

Asuka: Hibari, it's a yoma

Hibari: Let's go

Then they followed the yoma's roar.

(Timeskip with Yagyu and Katsuragi)

Now we see Yagyu and Katsuragi jumping on buildings to buildings looking for the yoma in uptown of Asakusa and Katsuragi ask Yagyu.

Katsuragi: Hey Yagyu

Yagyu: Yes Katsuragi

Katsuragi:*seductive look on her face* Did you have sex with him?

Then Yagyu stop at a building with blush on her face and she smack Katsuragi head.

Yagyu:*blushing* WHAT ARE YOU TALKING ABOUT?!

Katsuragi: What?

Yagyu: NO, I NEVER DO THAT TO HIM!

Katsuragi: I do and but why?

Yagyu: Because when we were hanging out Y/n ask me that I always protect her like a sister and I said yes to him, I ask him that do he have siblings but he said no and he told that someone who name is Longclaw is like a mother to him but he have to leave because some people want his powers and he started to cry and I gave him a hug him to make him feel better and I told him to remember what he to me during we met him

Katsuragi: What he said?

Then they heard a roar coming from uptown of Asakusa.

???2:*ROAR!*

Yagyu: Katsuragi, it's yoma

Katsuragi: Let's go after it then

(Timeskip with Ikagura and Y/n)

Now we see Y/n and Ikagura jumping from building to building and then Ikagura have a blush and she stop on the last building and Y/n stop too and ask her.

Y/n: Are you ok Ikagura?

Ikagura:*blushing* Yeah, but can I ask you a question?

Y/n: Sure what is it?

Ikagura: After this mission can we hang out together?

Y/n: Sure, I'll glad to, but can I ask you a question too?

Ikagura: What is it?

Y/n: Does Katsuragi always like that?

Ikagura: Like what?

Y/n: When she hugs, she always put me close to her chest and saying things that make face red

Ikagura: Don't worry Y/n, she always like that but when you know her better, she'll treat like a big sister to you

Then she felt Y/n hugging him making her blush.

Y/n: Thank you Ikagura

Ikagura then hug him back.

Ikagura: No problem, Y/n

Then they heard a voice and a growl out of nowhere.

???: Wow, how touching

They then turn to see a teen boy with fair skinned with dark blue eyes, black hair which covers most of his forehead do to his long bangs, and even going further, as to cover some of his eye, and going down to his nose. It also goes well down to his ears, nearly covering them up as well, He wears a dark blue vest or shirt underneath his long white coat, and both tops are also constantly unzipped, he wears white pants as bottoms, and black shoes, and he holding an kusarigama with some monster wearing bronze armour and holding swords and a red monster holding a club. And they have a mysterious aura around them.

                                     (A/n: Ten of them)

And Ikagura know who that person is.

Ikagura: Murasame?

Murasame: Hello there little sister

Y/n: Who?

Ikagura: Y/n, this is my brother Murasame

Murasame: And you're must the blue blur, it's time to get rid of you

Y/n: What?

Ikagura: You can't do this

Murasame: Yes I can and I kill you with him

Ikagura: Who's making you doing this?

Then Ikagura's phone started to ringing and she then picked it up and it was Asuka.

Ikagura: What's happen Asuka?

Asuka(on the phone): I don't we were just fighting the yoma then out of nowhere, there was some monster with knight armour on

Ikagura: What about Katsuragi and Yagyu?

Asuka(on the phone): I don't know they haven't call me*static* m-me a-and H-hibari n-need s-some hel-

Ikagura: Hello, hello

Y/n then started to shaking in fear while Murasame have an evil smirk on his face.

Murasame: Just a shame, look at the blue blur and you scared just pathetic, SOLDIER-ONE ATTACK!

Then the soldier-one started to charge at them and Ikagura said to Y/n while he still quivering in fear.

Ikagura: Y/n, keep it together

Y/n:*scared* B-but I'm scared that my friends are getting hurt

Ikagura: Don't be scared, I know our friends can stop those monster and also I'm here with you

Y/n: Really?

Ikagura: Yes and now let's beat these monster

Y/n: Right

Y/n then pulled out Caliburn and got in his position to fight.

(Y/n and Ikagura vs Solider-One, ready? GO)

Y/n's arm then glowed electric blue and eyes change from emerald green to electric blue and he have his arm in a ball throw position.

Y/n: HIDDEN NINPO: LIGHTING LAUNCH!

He then launch a bolt of lightning at the two soldier-one making them electrify and making them explode and Ikagura was surprised on how he did that.

Ikagura:*surprised* How did you that?

Y/n: I was focusing on my left to do it

Ikagura: Well,that's cool

Murasame: No matter, GET THEM!

Then more Soldier-one comes to Y/n and Ikagura then she said to him.

Ikagura: Can you handle these monster alone?

Y/n: I can, go and stop your brother and that yoma

Then she nodded at Y/n and ran to Murasame and all the Soldier-one surround him.

Y/n: Alright, let's get this thing started

Then he got into his running position while he got his sword out.

Y/n: HIDDEN NINPŌ: SLASHING PINBALL!

He then dashed at the first Solider-One and slash at it the he bounce off of it and then at the second Solider-One and slash at it and repeatedly at all of them and at the last one, he then released an EMP wave at them making them explode.

(Y/n wins)

Y/n: Alright, now it's time to help Ikagura

Then the red yoma then smash her club at the ground making Y/n fall down.

Y/n: Hey thought you going to with him? Gotta change of mind?

Then the red yoma then smash her club down at Y/n and he dodge it and he was thinking while he was dodging.

Y/n:*thought* I wonder how Ikagura doing?

(Ikagura vs Murasame, ready? GO!)

Meanwhile Ikagura and Murasame are now in a fight and Ikagura said to him.

Ikagura: This isn't you, please stop this

Murasame: This is me and I'm defeating you

Then he swung his kusarigama at her but she blocked with her sword then he said with anger.

Murasame:*anger* I'M ONLY ONE WHO SHOULD OF HAVE THE HEIR NOT YOU!

Ikagura: Please stop this

Then his kusarigama glowed dark purple and yellow aura around and he swung it around while his became white.

Murasame: HIDDEN NINPŌ: KING ARTHUR STYLE: FINAL DEATH!

Then he slashed his kusarigama at Ikagura but she was trying to block but got slashed making her clothes rip apart and flying at the vent crawl.

(Ikagura lose)

Meanwhile with Y/n and the red oni, he was dodging of her attack but then there was a dark purple aura around her and she dashed towards to Y/n and grab him by the neck and slammed him down making the center of Asakusa shake.

Meanwhile at a different building, we now see the black hedgehog wearing armour closing his but he felt a shake from somewhere making open his eyes and he saw the same building where Ikagura and Y/n see fighting and he said with a smirk under his helmet.

Black hedgehog: Looks like I found you

He then jumped from building to building.

Now back at the battlefield, we see Y/n bruised up and his shinobi form is rip apart and Murasame walked up to Y/n and he grab one of his quills and pick him and looked at him.

Murasame: Tsk, tsk, tsk, just look at you, can't even defeat an yoma just pathetic

Then he drop Y/n and he was about strike Y/n but he heard a attack coming at him and he saw Ikagura.

Ikagura: HIDDEN NINPO: HIEN HÖSEN: MODE ONE!

She then dashed at Murasame with her sword and Y/n said to her while he was down.

Y/n:*weakly* Please don't do this

Murasame: You're still up looks like I have to finish then

Then he gripped his kusarigama while he have an dark purple aura around him and said finishing attack.

Murasame: HIDDEN NINPO: KING ARTHUR STYLE: FINISHING SLASH!

He then swung his kusarigama at Ikagura with dark purple aura around it and slash at her making her clothes gone and flew into the vent crawl. When Y/n saw it his eyes have tears in them when Murasame walk up to Ikagura and she said to him.

Ikagura:*weakly* Please don't do this, you're my brother

Murasame: And you're not my sister then, say goodbye

When Murasame about to end Ikagura, Y/n then felt something snapped inside making his fur dark blue and aura around.

Y/n: Don't do this Murasame

Then Murasame turn to see Y/n with his fur turned dark blue and have smirk on his face.

Murasame: So, you still up already? Red oni finish him

Then the red oni charged towards Y/n but he then have a evil smile and said.

Y/n: No, I'll finish you

Then he disappear out of nowhere and reappear in front of the red oni and slashed her into half with his hands that made Ikagura and Murasame surprised about this and when the red oni got cut in half, it explode making them covering their face and when the smoke cleared up they Y/n but he looked different. Now his fur is dark blue with dark blue eyes, wearing his torn up shinobi form.

                (That's as a kid and wearing your torn up shinobi form)

Ikagura:*weakly* Y-y/n?

Murasame: You think you can stop me in that form?

Y/n didn't say anything but he gesture him to come at him and that made Murasame angry.

Murasame:*anger* ALRIGHT THEN LET'S GO

(Dark Y/n vs Murasame, ready? GO!)

Murasame then swung his kusarigama at Y/n but he grabbed it with one hand and pulled him to Y/n and punch him in the guts making Murasame spit out blood and flew into another building. Then Y/n jump to the same building where Murasame is and shot a dark blue lighting bolt at him but he blocked it with his kusarigama.

Murasame: Is that you're best shot?

Then Y/n disappear out of nowhere and reappear in front of Murasame and uppercut him into the air and did a axe kick to the ground making it have a cater.

Meanwhile, we see the black hedgehog wearing armour at a building away from Y/n and Murasame and he saw them fighting.

Black hedgehog: Hmmp, I better stop Y/n before he destroy that city

Then he sensed another energy but it feels like it's fading.

Black hedgehog: And I better find that energy reading before he/she die

Then he teleport to location where the fading energy is.

Back at battlefield, we see Murasame in the cater laying down and Y/n floating above and he said to Murasame with a large dark blue lighting bolt in his hand and everybody in the center of town was this.

Dark Y/n: Die

Before he could do final hit, he heard Ikagura.

Ikagura: Y/n stop

He then turn to see Ikagura and the black hedgehog and he said after he drop the lighting bolt.

Dark Y/n: Ikagura?

Ikagura: Please don't do this Y/n, this isn't you

Then Y/n looked at Ikagura in the eyes and they tears in them making Y/n feel sad and he then got out of the form and pass out.

(Match tied)

Ikagura comes to Y/n and Murasame both knocked out and she felt sad about her and Murasame battle when he said 'I'm not your sister'.

Black hedgehog: Is there something wrong?

Then she turn to see the black hedgehog wearing armour standing there beside her.

Ikagura: It's just that when Murasame and I were fighting he said that he's not my brother

He then looked at the knock out Murasame and he sensed a evil energy on him but it faded away and he remember the evil energy.

Black hedgehog: You know, he was control by someone

Ikagura: Really?

Black hedgehog: Yes and we need to get them to somewhere to heal

Ikagura: I think I know where

Black hedgehog: Where?

Ikagura: It's the Hanzo Academy

Black hedgehog: Let me teleport us there

Then she picked up Y/n and the black hedgehog hold Murasame and held a emerald and said.

Black hedgehog: CHAOS CONTROL!

Then they teleport to Hanzo Academy.

(Timeskip)

In the Hanzo Academy infirmary, we see Ikagura and Black hedgehog waiting on Y/n and Murasame to heal up and Ikagura heard Asuka.

Asuka: IKAGURA!

Then she turned to see Asuka and the rest of the Hanzo Girls and she said to them.

Ikagura: Are y'all ok?

Hibari: We're fine thanks to him

Yagyu: Yeah, couldn't done it with him

Black hedgehog: No problem, it's at least you take care of  Y/n

Katsuragi: What do you mean?

Black hedgehog: I'll tell y'all when they wake up

Hibari: What do you mean 'they'?

Ikagura: He mean my brother here as well

All: WHAT?!

Asuka: Why is he here?

Ikagura: Because me and Y/n were finding the yoma and he came out of nowhere with monster holding sword and a yoma

Black hedgehog: But he was corrupted by an mysterious a aura around him

Ikagura: Y/n was fighting the monster but then a yoma was in his way to help me and I was fighting Murasame but he use an attack that I never heard of and the yoma defeat Y/n

Black hedgehog: Making me heard it from the another building

Yagyu: Why were you at the another building?

Black hedgehog: Because I was looking for him

Asuka: Why?

Black hedgehog: Because he have a sacred weapon that can defeat evil

Katsuragi: A sacred weapon?

Ikagura: What do you mean?

Black hedgehog: I'll tell you when he wakes up

Meanwhile in the infirmary, Y/n and Murasame are now unconscious on the infirmary bed then Y/n's hand started to move and Y/n was started to wake up.

Y/n: Ugh, what happened?

Then he looked around and he was in the infirmary.

Y/n: I must be i back in the Hanzo Academy

???: Wait did you just said Hanzo Academy?

He then turned to see Murasame wake up and started to scream.

Y/n: AHHHHHHHH!

Now back at our if the infirmary, the Hanzo Girls and the black hedgehog were now waiting on Y/n and Murasame then they heard Y/n screamed.

Y/n: AHHHHHHHH!

Hibari: It's Y/n

Ikagura then see Murasame wake up too.

Ikagura: Murasame

She then comes to Murasame and have him a hug and she let go then he ask them.

Murasame: What happened?

Black hedgehog: You were corrupted by an evil spirit

Y/n: Who are you?

Hibari: I'm asking the same question too

Black hedgehog: Well, I'll tell y'all

Then he take off his helmet and revealed his crimson red eyes and then the girls were surprised.

All: YOU'RE A HEDGEHOG!?

Shadow: Yes, my name is Shadow but my codename is Lancelot

Y/n: Shadow? Why is that familiar?

Shadow: Because Y/n, I know you're father

Y/n then went to Shadow and said while he jumping up and down.

Y/n: Where is he? Where is he? Where is he? Where is he?

Then Shadow out his hand on Y/n shoulder and make him to calm down and put him in the ground then they heard Kiriya voice.

Kiriya: Who are you?

They then turn to see Kiriya standing at the infirmary door and the Hanzo Girls and Y/n said together.

Hanzo Girls and Y/n: KIRIYA-SENSEI!

They then bowed to Kiriya and he said to them.

Kiriya: There's no need to bow

Then they stop bowing and Kiriya looked at Murasame and he have an nervous smile on his face and said while he waving.

Murasame:*nervously* H-hey Kiriya

Ikagura: Kiriya-sensei, we can explain

Kiriya: There's no need to explain

All: What?

Kiriya: I saw it on the news and including you too Y/n but different

Hibari: What do you mean?

Shadow: I think I know what it means

Yagyu: Then tell us

Shadow: That form you saw Ikagura was his dark form

Ikagura: Dark form?

Asuka: What's that mean?

Shadow: Dark form is form only can be use when the user have all the intense anger and rage

Then when they heard that Hibari started to shiver in fear and Ikagura then ask Shadow.

Ikagura: How that happened?

Shadow: It only happen if he get angry or have rage

Y/n: Uhh, Shadow?

Shadow: Yes, Y/n

Y/n: I think I know what happened

Shadow: Then tell us

Y/n: After my battle against with the yoma, Murasame picked me up and call me pathetic then Ikagura try to attack but he then blocked the attack and swung his weapon at her making her almost pass and before he could finish her off something inside of  snapped and that's how I got into that form

Shadow: Hmm, it must be you're relationship with Ikagura that the anger inside you wouldn't let her get killed

Murasame: So, what about me?

Shadow: As I said, you were corrupted by an evil spirit

Then Kiriya looked at the window and see it's almost night.

Kiriya: It's almost night, y'all need to go including you, Murasame

All: Yes sensei

And they left the infirmary except for Shadow.

Kiriya: Shadow, was it?

Then the word Caliburn echo in his head and he remember something.

Shadow: You mean Excalibur

Kiriya: Yes, I'll need your help with Y/n to train him to use that sword correctly

Before he left Kiriya said to him.

Kiriya: Before you leave Shadow

He then gave Shadow an dorm room and then said to him.

Kiriya: Here you go, your own dorm room

Shadow: Thanks

Then Shadow left the infirmary room.

(Timeskip)

Now Y/n is sitting on Ikagura's bed waiting on her to get done taking a shower while doing that he was having flashback.

Flashback starts

Now we see Shadow and a different hedgehog but he looked like Y/n but he doesn't have blue fur on his arms but have peach arm and belly wearing red sneakers with white straps and gold buckle, gloves, and a wearing a gauntlet and holding Caliburn.

Shadow: So, what we going to do?
