Every new student in Shinō academy was considered untrained and eventually after their first year that they are considered as a Practitioner.
Every one of the Zankensoki was divided into 4levels depending on their mastery. These were Practitioner, expert, Master and an unknown rank that was just to say that the person was above a Master. This was a title that mostly is used for someone like Yamamoto who can't just be called a master in Zankensoki and thus calling him a Grandmaster won't be too much.

{Zanjutsu training hall}
Currently the entire class as well as instructor Hokutō was godsmacked at the sight in front of them. Even Onobara who was their to observe his students's behaviour in class was Completely baffled by what was happening.
'Oh this reaction is much better than what I was hoping for'. Thought Mugai as he held Yashahime in her true form as a purple sheathed Zanpakutō. (An: again Zoro's Enma).
[I am now within you as well as the sword].
"That's impossible!". Hokutō yelled as he looked at the completely awakened Zanpakutō in Mugai's hands. In all his life he hadn't seen such a phenomenon occur ever.
"Student Mugai, do you know the name of your blade". Onobara asked in awe.
"Yup I can release her anytime". Mugai responded.
"Very well it seems it really is a completed Zanpakutō, Congratulations on being the first person to awaken a Zanpakutō in less than a minute after getting an Asauchi". Onobara said as he was still dazed.
The entire class erupted into noise as many students started to talk amongst themselves.
"A Zanpakutō, he has a Zanpakutō does that mean he is a Shinigami now".
"The guy isn't just some Bishonen but also talented. What the hell?".
"That guy he is fucking epic". Renji said to Kira.
"Ya it's been months since I had mine and it hasn't even showed signs of any change". Kira replied.
Meanwhile Mugai walked towards Hitsugaya and Momo who were looking at him.
"Ni-san how did you do it?". Tōshiro asked him.
"Just pour your Reiatsu like pa and pa, pha pha and pow it's a sword". Mugai explained as everyone who was listening deadpanned.
"I am just joking. The trick is just don't have any hesitation. It's because you think that the sword is something else that you fail. Just remember the blade is You!". Saying so Mugai walked out of the hall and no one stopped him.

Gengorō was currently in the principal's office as he reported the happenings to Sasakibe Chojirō who was astounded to say the least.
"And where is student Mugai right now". Chojirō asked as he wanted to report this to his captain and school's founder Yamamoto.
"Well after he left the Zanjutsu hall he didn't show up untill the Chemistry lecture after lunch, when asked where he was?, he simply said that he was in the library and then attended all the classes after that however he then returned to the library again after talking to me". Onobara said.
--------
Mugai understood a couple of things on his first day at the Academy which was that most things that where taught in the class such as Physics, chemistry and Biology where something he already knew. Medicine and calligraphy on the other hand, he had no idea about any of it. He also knew how to read and write Japanese and English somehow and was also able to speak both.
He was currently at the library looking at the basics of kido, he had already read the Theory of kido and just by reading once he could memorize it completely. The library had upto kido number 40 in both Hado and Bakudo however very little knowledge was available about Kaido. It seems that one needs to join the 4th division to learn Kaido after all. Although according to the librarian one could learn upto number 60 in hado and Bakudo If they have a special instructor that they request using the accelarated program of the special class. Being in class 1 had a lot of such perks.
After reading the theory of kido and using his Reiatsu to create a little bit of each element on his hand like a ball of fire, wind, lightning, water etc he went back to the row of books and took the basics in medicine and started to read it. He had already decided to spent a day in the library and learn as much as he could about all the non-combat subjects.
---------
[2 days later].
Mugai came out of the Library and went straight to the dorm as he slept. He was used to being extremely hungry and thirsty to the point of starvation so food wasn't a problem for him.
After sleeping for what looked like a day Mugai woke up and went towards the bathroom. Took a shower and brushed his teeth and went to the cafeteria of the school to get something to eat. Then he went to meet Onobara gengorō to talk about the accelarated program.

Currently Yamamoto was talking somethings with Ukitake and Shunsui. Nanao and Kaien where also present with them listening to their conversation when Chojirō Sasakibe ran in.
"Eijisai-dono!.. I have to inform you of something!".
"Don't rush Chojirō, calm down and answer what happened?". Yamamoto reprimanded him.
"I am sorry Eijisai-dono However it's important, it's about student Mugai!".
Hearing this Yamamoto opened his one eye. Everyone in Seiretei who was a seated officer knew about Mugai by now. The kid who awakened his Zanpakutō after just touching it.
"Hm what did the brat do now!" Yamamoto asked and Ukitake was also interested.
"He has applied for the accelarated program test for Zanjutsu, Hakuda and Hoho all at once..the reason i reported it is because he hasn't attended any of those classes".
Yamamoto upon hearing this opened one of his eyes and looked at everyone.
"When is the exam Sasakibe-san". Shunsui asked.
"It's within 30 minutes". Chojirō answered.
"Well then let's go see Ukitakē, Are you coming Yama-ji?, you guys should also come Nanao, Kaien". Shunsui said as he got ready to go.
The six of them then Shunpoed towards the academy and got their in minutes as they entered they saw Soi-fon standing their as she greeted them.
"Captian commander?. What brings you here?". Soi-fon asked in a polite tone.
"We came to see the kid just like you". Shunsui answered.
"I am not here to see him, I just came because apperently someone from the Fon family who is in my Unit is going up against the Him".
"Hm but I thought the Secret force was only to be commanded by The Commander of the force, but the way you are saying it means that he the member acted on his own regard". Ukitake asked.
"He was probably bought out by some noble family trying to cripple the kid most likely..And judging by the fact that they bought out a Fon family member means that they are pretty up their.". Shunsui said.
Yamamoto gripped his cane a Little tighter. He wasn't a big fan of the nobles doing Dirty business to his Shinigami especially using the Gotei 13 forces.
"Hoho this is quite the Gallery, Even the Captain Commander is here, I guess i wasn't Wrong in coming here?". An elderly man with slate gray eyes, a gray mustache, and long gray hair wearing the standard captain uniform along with a white scarf commented. He was Kuchiki Ginrei.
"Oh Captain Ginrei?, Are you here to Watch the Exam as well?". Ukitake asked.
"Hm in a way, my grandson is the special instructior for the 6th year's Accelerated program hence he was appointed to Test the Kid in Zanjutsu". Ginrei explained and Most people were taken aback excluding Yamamoto.
"Isn't that Hurdle a bit High for the kid?". Shunsui asked.
"That is if he makes it out of the Hakuda part first". Soi fon commented.
"It seems that Chojirō has setup our Seats let's go". Yamamoto commanded and Everyone Followed.
(An: Currently Byakuya is just a member of the Squad 6, also his father aka Sojun is already dead).
