After the current first-year class they taught was over the next one is coming in and this was the class were team RWBY and NPR are, and Jaune was able to easily spot and he saw them take a sit with each other and Sun and Neptune seems to be with them but are being ignored especially Neptune due to his advances towards Weiss.
"Alright class, today we are going to be training in handicapped situation, but first who would like to volunteering to have a tournament styled sparring before we get started with todays lesson." Glynda asked.
Sun raised his hands, wanting to volunteer and pick Jaune as his opponent as a sort of payback for scaring him about getting expelled, unfortunately, Sun still did not know that Jaune was a Professor and not a student so, he is going to get his ass kicked six ways to Sunday.
"And you are… ah, Mr Wukong from Haven." Glynda said not knowing who he was until she looked at her scroll which showed Sun's information.
"So, who would you like to challenge." Glynda asked Sun.
"Him." Sun said pointing at Jaune. This got a laugh from everyone since they know that he was going to get his ass thoroughly kicked if Glynda accepted his request.
"Mr Wukong, Jaune is-" Glynda was going to inform Sun that Jaune was not a student but was stopped by Jaune.
"I don't mind fighting him, Ms. Goodwitch." Jaune said to Glynda which she easily caught on when he called her Goodwitch rather than by her name, she realised that Sun did not know that Jaune was a teacher and was challenging him without properly looking at his timetable that has both her name and Jaune's listed as teachers.
"Alright, Mr Wukong head on to the lockers and retrieve your weapons." Glynda said.
After Sun went to the lockers Neptune heard some of the students still laughing at Sun.
"Oh, this is going to be so funny." Student 1 said.
"I know right, it's like the start of the first semester when a lot of the students challenge Professor Arc to a spar thinking that they can easily beat him." Student 2 said.
"I am so going to record this, and upload it to dust tube." Student 3 said.
Neptune was shocked when he heard some students call Jaune a Professor, now he was very nervous for Sun since he was not going to be fighting a student by a teacher.
"Well, shit. Sun is going to get his ass kicked badly." Neptune said to himself.
"So, Neptune. How well do you think Sun is going to do, now that you know Jaune is a Professor?" Yang asked Neptune while smirking.
"Not good, not good at all." Neptune said sweating bullets.
"Trust as when we say this, not even with all RWBY, NPR, and CFVY combined, we still could barely touch him, every time we think we got him, he would suddenly dodge as if he can predict the future." Pyrrha said. Now Neptune is really worried about his partner when the invincible girl is saying that a few teams combine can't even touch him.
"Well you don't have to worry too much since, Jaune barely get serious, when people challenge him to a spar in class, the worst he did was completely shatter a person's aura in a single hit." Weiss told Neptune.
'A single hit! He shattered someone's aura in a single fucking hit! And that's him holding back.' Neptune thought.
While Neptune was thinking to himself Sun came back from the lockers and was ready to spar, he even gave Neptune a thumbs up, which Neptune just gulped at. Sun headed to the arena and so did Jaune.
"Are you ready." Glynda asked both Jaune and Sun and gave her a nod.
"3…2…1, start." Glynda signalled. Sun was looking for opening's but Jaune just looked at Ruby and spoke to her.
"Ruby, I have taught you and trained you for a few months now, so, now I will show you a technique that is perfect for you since you are a speedster and speed is your forte, but I saw a massive down side to your semblance, it maybe speed base but your maximum speed is two hundred and fifty miles per hour, so I will show you my accel turn, what I'm about to show you is its slowest variant and then in the future I will teach you its upgraded version." Jaune told Ruby and she got excited to learn a new technique and its speed based no less.
When Sun saw that Jaune was not taking him seriously he rushed towards him converting his staff to a dual nunchaku. But when he was about to real Jaune he suddenly disappeared, to everyone that was what it looked like, but to Ruby and the others they saw him blurred behind Sun.
"This is accel turn, Ruby. Next I will show you Tempest turn." Jaune said.
Jaune used tempest turn which made it looked like he made a clone, but to someone like Blake who can make clones, she knows this is not the case. Jaune hit Sun on the head, both his arms, his back and his leg at the same time. Tempest turn is not a very fast movement since it concentrates on making after images.
"Next, I want to show you what it looks like, when I combine both Accel Turn and Tempest Turn." Jaune said.
Reaching a speed of three hundred eighty miles per hour Jaune made multiple after images that attacked Sun in multiple directions at the same time, he never stood a chance when Jaune combined both moves since not only were there a lot of afterimages, it was also all moving at three hundred eighty miles per hour. Of course, Jaune did not hit Sun very hard since if he did then Sun's aura would already have shattered in the first hit.
Ruby and everyone else was amazed at the technique, even Glynda since she has never seen anyone without a speed semblance move that fast. Ruby was very excited to learn both techniques since she knew that her semblance had some limitation, but now she is imagining using her semblance with that technique, she could cause so much carnage in the battlefield, Ruby even nearly loudly chuckled evilly.
After the fight, Glynda approached Sun.
"Jaune Arc is the victor of the match; Next time please chose your opponent wisely next time Mr Wukong as it is not a wise idea to challenge a Combat Professor." Glynda told Sun. Sun was now wide-eyed she just called Jaune a professor, he just challenged a professor.
'Oh man, now my team is going to make fun of me for challenging a professor and getting my ass kicked, I could not even track his movements, let alone try and touch him once.' Sun thought.
The class continued, they had a training session on the handicapped situation, such as when they have barely any aura or they are protecting a cargo, or that they have an injured in their group, they did many different handicapped situations, after the lesson Jaune headed to his base to have some lunch since he does not like cafeteria food and he knew that teams RWBY and NPR will soon follow, so he got started and made lunch for everyone. He also made lunch for Glynda and he went and gave it to her when he finished making it, and he did it before team RWBY and NPR arrived.
When RWBY and NPR arrived, they bombarded him with questions about the accel turn and tempest turn. Jaune explained to them that he will teach all of them to be able to do what he did but they must first condition their body to withstand that kind of speeds before even trying to use the technique or else they will be badly injured, he also told them he is willing to teach the technique to Ruby early was the fact because her semblance makes her body already condition to go at fast speeds.
After lunch, everyone went back to there class which was Grimm studies and Jaune was going to his lecture room teach those who want to take his class. But after classes, he heads back to his base to train RWBY and NPR.
Unlike in the original, by now team RWBY should be preparing to investigate the White fang meeting but instead, they are all with him training except for Ruby who said that she met a friend and is bringing her over which he said is fine she met her again after the first meeting when Weiss bumped into her at the docks, and according to Ruby she was a bit weird but is eager to make friends and is super friendly. From the way, Ruby talked about her friend he already knew that it was Penny.
'I guess, since Penny was not involved in the docks incident Ironwood did not restrict her movement, and she is now headed here with Ruby.' Jaune thought.
It did not take long before Ruby arrived with Penny, she looked just like the show, but if one was to slightly observe her more they will see that her eyes are censors and the fact that she is not even breathing.
"Hey guys, I brought Penny with me since I met her after I went to the cafeteria for some snacks." Ruby said.
"Salutations, I am Penny Polendina." Penny said in a very peppy voice.
"So, do we introduce ourselves again or do you remember us." Nora asked.
"No introduction necessary, I remember every single one of you, except for you, I have never seen you before." Penny told RWBY and NPR the first part before turning to Jaune and saying the next part.
"Names, Jaune Arc." Jaune said.
"Salutations, my name is Penny Polendina." Penny said once more.
"You already said that." Jaune told her.
"So…I did." She said.
"So, Penny, where are you from." Jaune asked.
"I am from Atlas. I am here to participate in the upcoming Vytal tournament." Penny said.
"Well, you are welcome to train with us, if you want." Jaune told her.
"That would be wonderful. Penny said.
"Well, alright then." Jaune said and everyone started with their warm-up.
After their warm-up they separated to groups, depending on what they are supposed to be training in, right now team CFVY is not training with them since they were sent for a mission to Lower Cairn. Pyrrha was training her swordsmanship, Yang was training to control her semblance, Weiss is also concentrating in her summoning to try and speed it up, she is also training to increase her strength, Nora was training to control her aura more to be more efficient so that she is not using too much at ones. Blake was training to increase her strength more since she is fast and nimble enough, Ren was increasing his stamina and endurance, and lastly Ruby was training with Jaune trying to learn how to use Accel turn and Tempest Turn.
Meanwhile, Penny was just watching them train, she was amazed at how Jaune is splitting his time training each one, making sure to help them when they ask or when he sees them doing something wrong. And then lastly, she saw Jaune teaching Ruby two techniques she has never seen before and she could not comprehend how they work, but from what she can see, Ruby was able to learn a bit of it, she was a bit jealous with the way both teams interacted, they seemed like a big family, Penny felt jealousy but she did not know what it means.
The more she watched the more jealous she got since back in Atlas she could not make any friends since, the General was always telling her about her destiny and her purpose how her time will come, but all she wanted was to make friends since she was already here so why not try to make friends with them. So, she went towards the group.
"Can I join with you guys." Penny asked Jaune.
"Sure, why not. Come on, right now I am teaching Ruby a speed-based technique, but to use the technique it requires the person's body to be strong enough to with stand immense amount for force which Ruby is capable of due to her semblance." Jaune said, he did not mind telling Penny about it since to use it, one must know how to circulate aura around the body, reinforce it enough and time the release of the gathered aura perfectly if the steps are not done properly, they risk getting them crippled for life, it is not a technique that anybody can just learn, even if they were able to imitate the procedure to do it, they still need a body that can withstand it which is near impossible, team RWBY and NPR are only able to learn it in the future is since they took the pills that bring out their bodies full potential.
"If you want Penny, I can teach you some martial arts techniques." Jaune said.
"That would be wonderful." Penny replied.
So, the next couple of hours they trained in the things they need to improve while Jaune taught Penny some martial arts like Judo and Jiu-Jitsu, she was happily interacting with him and the rest of the group, her jealousy in the beginning disappear and she genuinely smiles with them.
