3RD PERSON POV

*SLICE*

Y/N: 'These grimm are so weak. But my skills have gotten much sharper after fighting them for 3 days straight.'

Using clones to help out in the other world, he ran into an alternate version of Remnant and decided to train himself. Though he wouldn't improve in strength significantly, his skills with his big blade can be immensely improved and there was definitely progress felt.

Y/N: Nice. Very nice. Very-

*CRACK*

Y/N suddenly disappears, holding his big blade to the neck of a bunny hair girl who yelps.

Velvet: WAIT! I'M NOT AN ENEMY!

Y/N: 'Velvet?' Oh.....sorry.

Coco: Hey! What are you doing to my partner?!

Y/N: Apologies. I was merely training in these woods for 3 days.

Coco: Training? This forest is crawling with grimm. The headmaster has caught sight of a one armed swordsman around here, and wants us to bring you back. It's not safe- wait 3 days?

Y/N: No sleep, no rest, just kill and train.

Coco: You need sleep.

Later

Y/N: *SNORE*

His hand held his weapon close to the torso area. The two males were looking ahead, and the two huntresses stared at him as they see his scarred eye and his missing arm.

Velvet: *worry* Three days alone with grimm?

Y/N: *grunt* Like I said, it's training.

He wakes up, sighing as he sheathes his blade.

Coco: *whistle* Nice blade old man.

Y/N: I'm 18.

Velvet: E-EH?!

Y/N: Yeah I look old. But no it's my natural look. How old do I look?

Velvet: Like in your 30s.

Coco: Must've went through a-

*GRAB*

She lets out a surprised gasp as Y/N's blade slams to the floor and she struggles to lift it up.

Coco: HOW HEAVY IS THIS BLADE?!

Yatsuhashi: Let me try-

He struggles to even move the blade, shocking everyone on board as Fox joins in along with Coco and they barely manage to raise it an inch.

*GRAB*

Y/N: The blade's heavy.

Velvet: It looks rather bulky. Too bulky for a blade.

Y/N: According to the blacksmith I acquired it from, it was too big to be called a sword. Too big, too thick, too heavy, and too rough. It's like a big hunk of metal.

Coco: *impressed* And you carry that thing even with one arm huh?

Y/N: I normally fight with a much smaller blade.....but ever since I lost my arm recently I've been training to develop a knack for fighting with it.

Coco: Does it have any special features?

Y/N: Besides the weight and absurd durability? It's just a sword.

Coco: Hmm.....you could use a secondary weapon.

Y/N: Yeah. Maybe, but I'd stick with what I have as of now.

*WHOOSH*

Ruby: You came back- Woah that's a big blade!

Yang: And an old-

Weiss: Mature gentleman~

Y/N's face fell as the bullhead opens, and he was surrounded by students though two of them made him want to rip them apart.

Y/N: You good?

Yang: *smirk* Oh? What is that I'm hearing Weiss?~

Y/N's teeth grinded, seeing the two bitches-

Y/N: 'No it's not them. It's an alternate version. Don't be mad.'

Weiss: N-Nothing! *tch* Hmph.

Ozma: Ah. I see you're quite the unique warrior.

Y/N: I can say the same about you Ozma. You fucking ASS!

Ozma froze, a growl coming from Y/N's throat as his bloodlust skyrockets upon the sight of him.

Ozma: I am not who you think I am.

Y/N: How am I sure you aren't?

Ozma: Let's talk at my office.

He ushers Y/N through the academy grounds and up to his office where they both sat down alone.

Y/N: I'm not of this world.

Ozma: I have never met you before, so I'm inclined to believe that along with your.....frightening magical energy.

Y/N: Yes.

Ozma: What do you think of me-

Y/N: A fucking sack of shit. You manipulate everyone around you for your own goals. If someone's a danger or seems too dangerous, you'd have them killed. You never cared about the people, and only viewed them as pawns. YOU ARE A-

KILL

In his moment of bloodlust, he had his hand around Ozma's throat though pulled back as he grits his teeth.

Y/N: DAMNIT!

Y/N: I apologize......it's really unpleasant memories.

Ozma: I figured.

Ozma waits for the stranger to calm down, sensing Y/N's resentment and anger for him as he nods his head.

Ozma: However, I can assure you I'm not this kind of Ozma. I could sense the animosity from you directed to team RWBY.

Y/N: Yang and Weiss.........those fucking pricks-

Ozma waited as the ground shook beneath them and Y/N takes a breather.

Ozma: What's your goal here? What are you doing here?

Y/N: I was planning to train my skills and such for 5 days straight before YOU brought me here.

Ozma: Hmmm.........

He was in deep thought as Y/N explained his reasons, and asked some questions before giving a response.

Ozma: Maybe you want to be a combat teacher?

Y/N:.........

Ozma: It's a way to be stronger. You may not get stronger physically, but it could be a way to broaden your perspectives and sharpen your skills.

Y/N:......

Ozma: I won't force you to be a teacher-

Y/N: Hold that thought.

The Next Day

Pyrrha: H-Huh?!

Y/N: You will be fighting me one on one.

Y/N held his blade over his shoulder, bending down as team JNPR, RWBY, and CVFY watches in anticipation.

Y/N: NOW!

*BOOM*

Pyrrha blocks Y/N's sword though her body shook as she was sent skidding back.

Pyrrha: 'M-My arms are shaking!'

*CLANG*

They both swung at each other many times, many cheering for Pyrrha though the teams were surprised that despite the cumbersome weapon, Y/N was outmaneuvering the champion at every turn. Every blow was deflected, parried or countered. Every kick and punch were evaded.

*WHOOSH*

Y/N senses his blade shift from the champion's semblance before swinging it in a diagonal arc, catching her by surprise as she crashed into the pillar behind her.

Y/N: Oh......Ah shit.

Pyrrha: Wha-

*THUD*

The top half of her spear and shield dropped to the floor, a large cut appearing on her torso as she drops her weapons.

Glynda: Y/N! I thought I was told you were going to go easy!

Y/N: Uh.........sorry.

Pyrrha: It's ok. I can get my weapons fixed easily.

Coco:.......Please don't chop my weapon in half.

Y/N did so anyway which earned a lot of cries from people, especially the red head who clutched her brown scythe.

Ruby: MY BABY! YOU'RE IN TWO PIECES!

Y/N: Ok. Let me tell you....

Y/N: That you all fucking suck. Ruby, you're so useless without your weapon. Yang, you're so short tempered all you can do is throw your fists around like a doofus. Weiss, without your glyphs and dust you're like a sword fish without its snout flat chest. Blake, in a direct confrontation you pussy out and run away. Jaune I don't even know why you're this abysmally bad at fighting. Get rid of the shield and then there's potential. Ren, even a middle schooler has better stamina then you. Nora, every time you fight it's like smash smash smash. Except you're being a dumbass. Pyrrha, you're ok. But this isn't a tournament match. Threat it like a life or death situation. Treat me LIKE A THREAT, and not an opponent. And your semblance sucks if you rely too much on it anyway. Can't use the blade if I can flex on you with one arm.

Glynda: I THOUGHT I SAID GO EASY ON THE FIRST YEARS!

Y/N: They said a second year can't possibly face all of them at once. And Coco, your weapon may be good at range, but in short range it's jackshit. Your partners gotta step up. And you bunny.

Y/N: Don't rely on dust or semblances ok?

*RUFFLE*

He ruffles Velvet's rabbit ears as she squeaks.

Coco: *smirk* Well well well how the tables have-

Eri/Noah: PAPA!

*THUD*

The two toddlers flew like a heat seeking missile, smacking Y/N hard enough to make him crash into the other side of the room.

Everyone: PAPA?!

Y/N: *chuckle* Cmon now I'm in the middle of teaching.

Weiss: *dying* It.....hurts.....I don't......have a flat chest.

Y/N: 'Sucks to be you bitch.'

ALRIGHT WE'LL BE TEACHING THESE BRATS

BUT WE GOTTA KILL SALEM'S FACTION ALRIGHT? WITH THE DEATH OF THE GOD OF LIGNT AND DARKNESS IT AIN'T GONNA BE HARD AT ALL

Eri: *yawn* Mama is going shopping with Ei.

Daichi: ???

Ruby: IT'S SO ADORABLE!!!!

The students hoarded around the kids and Y/N sighs before turning away.

Y/N: 'Ok maybe this isn't the best idea.'
