Bleach System Within Bleach

Inside a hospital in Seireitei 2 figures could be seen talking to each other.....

??? : "Nia you should focus and refine more you're Reiatsu as it always overloads when you used your Kido...."

Nia: "Yes Captain Unohana....."

Unohana: "During those 4 months we learned that you're Kido can reflect almost all types and can help in the medic department...."

Nia: "YES!!!"

Unohana: "The only drawback is you're putting way too much Reiatsu in it and you can't even control that amount..."

Unohana: "Since you can't control is that it fails after 2-3 reflects..."

Nia: "YES!!!"

It was Unohana and Nia who was training under her.... As Unohana was watching her she felt a gaze looking at her.... when she turned her head towards the empty white wall, she was stunned and then was angry as the only thing she saw was a hand with a middle finger raised....

She then turned to look at Nia who was focused on her Kido... trying to input and raised her Reiatsu.. she sighed and told her...

Unohana: "That's enough for today... we'll continue tomorrow rest for now...."

Nia: "Really!!!!"

Unohana: "Yes go!!"

Nia was happy she that she got a bit of time as she went towards the door to leave, Sora placed his leg in such a way that made her trip and smashed her face in the Door.....

Unohana was speechless she was thinking does he have a grudge or something???... Nia was holding her face as she had tears from the pain and didn't know how the hell she fell... and even worse in front of her Captain...

As she left the room with tears in her eyes and a red face..... Unohana sighed again and spoke to the void.....

Unohana: "Was that really necessary???"

??? : "Of course she kicked my face when i saved her.. therefore i'll make her pay 100 times over!!! so far it's 2 times so 98 more....."

Unohana: "What do you need Sora??"

Sora: "To make you stronger... Are you interested??? First Kenpachi??"

Unohana eyes shined with fighting and killing intent, her eyes were completely opened and in her mouth a smile was formed....

Sora: "Really ungraceful..... No woman appeal at all...."

Unohana: "Say that again you brat.... i'm older than you...."

Sora: "You should be glad i said a woman and not hag... furthermore i'm way older than you haven't you learned the news???"

Unohana: "You are Weak..."

Sora: "Then let's see it... are you up in your peak old hag...."

Unohana: "Ku Ku Ku..... then let's head to the lowest level of the Central Great Underground Prison... where no reiatsu can flow out.. and none will bother us....."

As they said that they disappeared from there and headed towards the Underground... it was a dark place with barely any light but somehow you could still see who you were up against....

Head Commander who felt these movements he was shocked...

Yamamoto: "Is Yachiru going to return to those times???"

Apart from him 5 more had realized that something is going on.. something eerie in the air was lurking....

Zaraki: "Xmmm this feeling..... it's familiar..."

Shunsui: "Is she going to fight someone??? or train??"

Ukitake: "Probably train and get back to her peak...."

Chojiro: "................."

Aizen: "Xmmm That's someone i don't recognize was someone hiding in Soul Society this whole time???

All 4 Captains and the Vice Captain were scattered across Soul Society with their own thoughts, but inside the Underground... a deadly battle was about to begin....
