Disclaimer: I do not own Bleach or Freezing, they are the creation of Tite Kubo, Lim Dall-young, and Kim Kwang-Hyun respectively. This is a simple fanfiction made in the hopes that it will jolt up bored minds :D.

This chapter will be more of a description, after all I am taking it from the canon in bleach so until we reach where my story begins I hope that you will bear with the "Isshin:" and "Ichigo:" and other characters from canon being put in front of the lines, afterword when my part starts it will more readable so please bear whit me until then. Well then, let's started GERONIMO!

Shinigami- Zangetsu

Shinigami - Zangetsu Hollow

Shinigami- inner thoughts and flashbacks

…Didn't you hear me?! We said we would protect Karakura!

It's no use…there's no way we can do that…

You don't know that!

Yes, I do! You felt it, didn't you!? There's no way we can beat a freak with reiatsu like that!

I see. You understand his reiatsu, don't you…?

…Huh?

I'm going…aren't you coming?

-Looks away…..-

Will you sit there and cry that you couldn't protect anyone!?...Think about what it means that Aizen is heading for Karakura in Soul Society. If you don't go, it means everyone you wanted to protect and everyone else in Karakura as well, will die by his hand.

… the Senkaimon.

…I don't need you to tell me.

Beyond the Senkaimon inside the Dangai

Wait! Ichigo!

What!? Aren't we in a hurry!?

It's odd. I can't sense the janitor….

The janitor isn't that the reiatsu train thing, right?

…Yeah. It's not something a Shinigami can fight…but from the traces of reiatsu around, Aizen must have done something to it…

…Is it a bad thing it's gone?

It's not good to leave it like this…but…right now it is to our advantage. The Dangai is called the precipice world. It is cut off from Soul Society and from Earth, from both time and space. So the janitor is here to make sure no one stays too long. But without it here, I can teach you.

…Teach me? Teach me what?

The final Getsuga Tenshou. Here, I can teach it to you…

What do you mean…?

The "precipice world" is a place in which severed space is piled on top of one another, surrounded by raging streams of time.

Oh…kay…? I see…

It doesn't matter if you understand or not. The point is that the density of time within this place is extremely high when compared to the outside. To put it in numbers, I'd say 2000 time denser! When one year passes in the outside world, 2000 years pass here.

…Eh…?!

A long time ago, it was not only a passage to the material world, but also a penal colony. That's why the kouryuu current and koutotsu exist. Those caught up by the current become unable to leave this world, and lose their lives. If they're caught by koutotsu, they'll be thrown out to a greatly different point in time from when they entered the precipice world. However koutotsu isn't here anymore, which means this is the perfect change to buy some time. The precipice world is 2000 times denser time-wise compare to the outside world, meaning, 2000 hours of training in here will only equate to 1 hour out there. Soul Society has no way of sealing koutotsu, but there is a way to stop the kouryuu current. They call this "kaikyou kotei"(realm boundary fixation). Normally lower-echelon Shinigami come in by dozens and use a special method to pour in their reiatsu and fixate the current, but I can do it by myself. I'm going to suppress the kouryuu current until my reiatsu runs out. I'd estimate we have about 2000 hours until that happens; in layman's terms, just under 3 months. During that time, you're going to call it out.

Call it out…?

That's right. Call it out… from you sword, Zangetsu. The true form of the "final Getsuga Tenshou!" … They call that form "Jinzen"(blade Zen). It's something that's been worked out over thousands of years since the formation of Soul Society all for the sake of speaking with one's sword. Ichigo, all of the techniques you've mastered until now should all be ones you received by forcing them out. … Understand? In order for you to advance from this point, you need to journey through those thousands of years that you've yet to touch… now go Ichigo!

(Ok from here on I will start adding my own elements in the story!)

While entering his inner world Ichigo was surprised to find he was submerged in water, instinct kicks in as he tries to swim to the surface when he is suddenly pulled back and thrown into the surface of a building, followed by this, however, comes a calm and melancholic voice"... Calm yourself. How unsightly, you should be able to breathe."

Surprisingly in the place of old man Zangetsu, he finds a young man wearing a pitch black robe, with his head slightly tilted to the side questioning"...Well?"

"Who the hell are you? The only person that should be here is old man Zangetsu."

"That's quite a way to speak to the person who taught you how to breathe." Moving his right hand the young man shows Tensa Zangetsu.

"It is only natural that you do not know this form, since this is your first time coming here while you are in Bankai."

"Wha...!?"

"Hmm, I see that you are quite surprised by my current form, aren't you Ichigo? Well not that I blame you."

Still slightly unconvinced Ichigo asks "So let me see if I get this right, you are Zangetsu?"

"Wrong Ichigo, what is the name of your Bankai? I am "Tensa Zangetsu".

"So Tensa Zangetsu, what happened here? This place has changed since I last came?" Looking around he could no longer see the one cloud braking sky-piercing buildings, in place was his small hometown.

"What happened you ask? You happened Ichigo, you despaired, and you stopped believing in me. YOU STOPPED MOVING FORWARD ICHIGO!" Pointing around them in anger, "Look at this world! Your world was once full of hope, clusters of tall buildings piercing the sky! And now it's reduced to nothing but your tiny village! The rain that fell on this world has ceased, but now everything is underwater! It is all, Ichigo, because you despaired and stopped walking." In the next moment he appears in front of Ichigo and plunges his hand through his chest. "Gah!"

"…Ichigo. I cannot believe this. Right here and now, I will draw out the source of your despair!" Pulled out of Ichigo's chest was something or beater said someone that he wish he would not see again…his hollow in the form he had when he battle Ulquiorra.

"…Hey, it's been a long time, hasn't it?...Ichigo." "No….it can't be!" The astonished look on Ichigo face said it all.

"What's with that face? Don't you recognize me?" he says while removing his hollow mask and showing the grin underneath it.

"…Y…you…why…? You mean you didn't disappear that time…!?"

"…Have you forgotten? I told you, didn't I? If you truly wish to control my power, you'd better stay alive…until next time I appear…!" a sight escaping him.

"…Damn it…!" Despair griping his heart as he looks forward.

"Sorry to disappoint you king. It's a crying shame, isn't it?"

"What's with that look…? Why the weird mask…?" He asks hopping that what he sees before is not what his instincts are telling him.

"I see." says an unperturbed Zangetsu. "You've never seen this form yourself. This is how you looked when defeated Ulquiorra."

"This…is how I looked?"

"That's right. You fear this form so much. You are so afraid of this form, afraid your own destructive impulses will crush your heart, that you are unable to properly hollowfy."

"….So…? What do you want me to do about it…should I fight him now…!?"

"NO. He is not your opponent this time."

"It is the two of us as one" And so they merge together, becoming what they were at their origin, one and the same.

Now upon fusing, they take on a hybrid appearance: Zangetsu's white Bankai coat, black horn mask remnant, white-colored hair, and left Hollowfied eye, alongside Tensa Zangetsu's appearance and black Bankai sword. Stating they are two parts of a single being, the source of Ichigo's power, they begin fighting him.

"Well then Ichigo, do you finally understand who I am?"

"…Who you are?" What does he mean by that?

And done first chapter down, hope you like it, it is my first creation and English isn't my native language. Now please don't be too harsh one me. And I will need help with a beta reader if someone can help me.

Now some dex. : koutotsu - is the Dangai's equivalent to a street sweeper. The koutotsu appears once every seven days to cleanse the area - killing anyone and everything that makes contact with it - to assure that no one can loiter and take advantage of the time distortion. It looks like the same material that makes up the Precipice World, only molded into the shape of a bullet train, and a golden eye at the upper-center of its body. If the koutotsutouches a Zanpakutō or other spiritual weapon, the user and weapon are trapped, since the koutotsu 's body is flowing with the kouryuu current. The Soul Society has no means of sealing the a being is caught by the koutotsu, they'll be thrown out to a greatly different point in time from when they entered the Precipice World.

Kouryuu - is the current that is constantly flowing through the Dangai, in order to prevent enemies such as Hollows from using it. The current stops souls from moving, and even one foot caught by it makes escape almost impossible. It encompasses the walls, capturing anyone who makes contact with them.
