The Rebirth In Bleach
Day One Part: 1

Although they did not show it, Itsuki and Gin both sighed in relief seeing Rangiku return to his usual self. The two of them walked over to the chair that Rangiku saved amidst the gazes of others. There are 13 seats in each row with 4 in the side column and 5 in the middle. Rangiku was in the front row in the middle column.

"Hey Itsuki, Gin met my new roommate. His name is Isazaka Yuroe"

"It's nice to meet you, Minamoto-san, Ichimaru-sa..."

He bit his tongue. His voice was small and calm, if Itsuki and Gin were not sitting nearby then they probably wouldn't have heard it. She was a petite young lady wearing the typical uniform of the academy. 

His black hair was styled with a bun and bangs covering his right eye blocked the view. His remaining brown eyes continued to dart as if searching for a hole to hide from the previous mistake. Tears threatened to come out of his eyes as Rangiku tried to comfort him.

"It's nice to meet you, Isazaka-san" Gin replied with a casual expression and Itsuki nodded in return.

Feeling no ill will from the two, he looked calm but still looked as if he was trying to hide himself. The group of four continued talking to each other as the class grew larger until the room was mostly full. No one was sitting on the chair next to Itsuki because of the aura he was emitting. Many girls tried but gave up on feeling the drop in temperature and the dangerous gaze that Rangiku gave them. 

Gin simply acted as usual and paid no heed. Yuroe was quite surprised by Rangiku's change as she felt Rangiku was someone who was relaxed and approachable.

At 7:00 and the room calmed down. The same burly teacher appeared and came and stood in front of the podium. His voice echoed throughout the room

"Welcome to Shin'o Academy and congratulations on making it into Class 1. My name is Gengoro Onabara and I am the principal for the first year, 1st grade"

A short pause followed, as he looked around,

"You'll all be trained to be great Shinigami here. We only have one command 'Don't seek beauty in battle.

Do not seek virtue in death. Don't make the mistake of only considering your own life. If you want to protect the one you have to protect.Slicing the enemy you have to defeat from behind.' … … … …”

Speeches about rules and regulations were followed before he came to the task at hand.

"Now. General Knowledge. This module will discuss the things a Shinigami should know.

While it will not improve your fighting abilities, knowledge itself can be used as a weapon. You will also discuss tactics, what to do with certainty.the situation, what things can be done and what you should avoid in Seireitei."

The next class is the application of Reiatsu.

Reiatsu is the physical pressure created by a person's reiryoku (spiritual energy) when released. So all this time, Itsuki had not improved his Reiatsu but his Reiryoku while his Reiatsu increased his results.

The difference between spiritual pressure and spiritual energy is simple: Reiryoku is the amount of energy stored within their body or soul, whereas Reiatsu is the pressure exerted by a person's Reiryoku.

In other words, Reiryoku is potential while Reiatsu is energy used and can be felt by other spiritually aware beings. In general, those with high Reiryoku levels will often have the highest Reiatsu levels as well.

A skilled fighter can overcome someone who has a larger Reiryoku by having a larger Reiatsu. This was achieved by having greater control over their own spirit energy.

Reiatsu has many colors and shapes in which they are depicted and each depends on its user. It can be used either defensively, psychologically or offensively. Defensive because a person with a larger amount of reiatsu can effectively harden their skin, adding an extra layer of protection. This causes a person with low reiatsu to be unable to cut.

Psychologically, there are four ways you can use it: fear, stun, paralysis, and phantom pain.

High-level Reiatsu can cause those with lower strength to be hit by stun just by being in the presence of one of them.

Paralysis - When someone with a high reiatsu focuses on an opponent with a low reiatsu, they can knock them out by focusing their reiatsu on them

Ghost pain - A person with a higher reiatsu can make the opponent feel as if they are being attacked even though nothing has happened to them.

So, overall, a Shinigami's fight depends heavily on the amount of reiatsu the creature has.

Next comes rest. The group of four decided to get to know each other better. Yuroe is from Seireitei and is the daughter of a pair of Shinigami who work for the Gotei 13. They were just low rank Shinigami who did not even know their zanpakuto name. Because of his personality he had no friends and Rangiku was the first.

After the break was over they went to the Hakudo training hall. The teacher was there.

Hakudo is basically a hand-to-hand battle. Onmitsukido (Special Forces) is the most trained in this regard. Being one of the four basic Shinigami fighting styles, it is divided into five stages: Untrained, Practitioners, Fighters, Expert Hakudo Fighters and Hakudo Master Fighters.

Untrained - Users have not learned it or have just started it.

Practitioners - Ordinary users of this art who can face an average armed opponent. Those at this level are among the officers who sit and do not sit on the Gotei 13.

Combatant - The average user of this art can face an average armed opponent and make a decent effort against those whose size is many times over. Those at this level are among the officers who sit and do not sit on the Gotei 13.

Hakudo Combatant Experts - These art experts can face average armed opponents and those who are many times over in size easily. Those at this level were among the officers seated on the Gotei 13.

Master Hakudo Combatant - These art experts can face heavily armed opponents and those whose size multiplies easily, and, as mentioned earlier, are able to deal with heavily armed opponents, Onmitsukido is the most trained Shinigami in Hakudo. The captain of the 2nd Division and their 3rd seat, or head of the Detention Unit, was most often the master.

Hoho is a defensive fighting style that deals with footwork, it is one of the four basic Shinigami combat skills.

Hoho is an important skill for most Shinigami, which combines speed and agility. Hoho skill levels can be improved and improved through its concentration, training, and mastery. The leading practitioners of this technique are those assigned to Onmitsukido. Shunpo (Flash Step) is the greatest expression of the Hoho technique; however there are variations even within Shunpo, which can only be used by Hoho master practitioners.

Shunpo is a movement technique that allows the user to move faster than the eye can follow. The focal point that determines the basis of this technique is speed. Since speed is a major factor of this technique, this method is best characterized by how fast one can move from point A to point B in the least number of steps.

Shunpo can be categorized into four stages:

Untrained - Those who are in this category, have no skills for Hoho and vice versa, rely on walking to get where they want to be, and instead, rely on walking to get where they want to be, or have been extensively trained to increase their natural speed to a level that allows them to move very fast, even though it is clearly below normal speed. Shunpos.

Practitioner Shunpo – Practitioners of this technique can maintain fast movements for a short time, by seemingly only taking a few steps to bridge the usually long distance. Those who are practitioners usually use their knowledge of Hoho while engaging in combat.

Shunpo – Expert This technique is very fast, and can maintain high speed movement for a long time. Although not as fast as the master, they can follow quite effectively. Some degree holders are faster than others, but, nevertheless, the application of their techniques is highly advanced.

Master Shunpo – Master Shunpo is able to maintain high speed movements for a long time while using the fewest steps to achieve those movements.

Once the introduction is complete, the teacher then proceeds to complete some exercises that show the recruits some examples of Hoho
