Bleach System Within Bleach

??? : "Tengoku Gyakusatsu-Sha (Heavenly Devourer)"

BOOM!!!!!! All the soul realm started shaking scaring the hell out of Sora.....

The shaking went on and on for about 20 minutes and when it stopped the Soul Realm returned to its original colour of Sora's soul a mixture of 5 colours....

As Sora was looking at the changes before his eyes an old man appeared in front of him looking at him with deep purple eyes....

??? : "You can call me Gyaku...."

Sora: "I'm Xiaolan Sora..."

Gyaku: "I know i saw it.... more like i read it..."

Sora: "How....??"

Gyaku: "I'm a devourer i can eat everything from dreams to nightmares, knowledge everything.. Humans, bones, blood literally everything....."

Sora: "Gulp.... then since you saw my memories how do you define your Shikai and Bankai???"

Gyaku: "I'm having trouble to that as well, based on what i learned Shikai is a first stage released of your soul's powers with your sword soul which was born with you when you were born..."

Gyaku: "I also know that originally you are not this world inhabitant.... but both of us were born in your previous world... it would have been bad luck for me if i had to be passed to the next human..."

Gyaku: "But since you were brought here i was dragged along.... better for me i guess since i awakened...."

Sora: "That still doesn't help..."

Gyaku: "I know i'm thinking...."

Gyaku was looking at Sora for a way to filter his abilities as Shikai and Bankai... he kept watching him and eventually after a long time it hit him.... he's wearing black attire..... and i saw in his memories that Ichigo his other Zanpakuto Soul when he was using Bankai his clothes changed....

Gyaku smiled since he found the perfect fit of powers in the form of Shikai....

Gyaku: "Kid i found it..... you Shikai would be the other Kid's Bankai clothes, but before you reject let me finish..."

Gyaku saw sour eyes as he heard about only clothes.....

Gyaku: "Those clothes in Shikai will be blazed in dark flames devouring anything it touches restoring your Reiatsu up to a certain limit...."

Sora had sparkling eyes he figured out a combination of Barragan released attire and Yhwach of when he first appeared in Ichigo... it was as if his clothes burned....

Gyaku: "You got it Close enough..... this will leave you your hands-free for you're other Soul..... and furthermore since we both live in here as Zanpakuto Souls we will not affect each other...."

Sora wanted to try it right now so he sat down and closed his eyes in meditation....

He felt his mind becoming one with this space and after a few hours... he opened them again... Gyaku was surprised to see that his eyes had the Primordial Chaos Of Elements in them spinning as a vortex in his eyes...

Sora: "Eat And Drink, Devour And Swallow - Tengoku Gyakusatsu-Sha"

BOOOOOM!!!!!! Sora's outfit was burst and shredded to pieces while purple cloud engulfed him.. within 1-2 seconds the cloud was cleared...

Revealing Sora with an Ichigo's 1st Bankai attire clad in pitch black flames... the flames didn't burn him instead it made him relaxed....

Sora Could feel that he had unlimited power as these flames didn't use physical energy but directly his reserves in Reiatsu lessening the burden on his body when he was trying to raise his Reiatsu beyond his limit self-injuring himself...
