My big problem with Bankai is actually how to name it. If it was just finding a name for his Shikai then that's fine, because I already have a nice release chant and name; but the name I have cannot be upgraded. Like Zangetsu into Tensa Zangetsu and so on.

As for my story being placed in other branches, I indeed thought about sending MC into Asgard for a few chapters, but as there's limited amount of information about that realm, I have some doubts if I can manage it properly.

Also, about his new ability Innovate Clear. It was suggested to me by a friend, and after reading it a bit on a wiki I decided to implement it. But I've never been too much into DxD, and I'm not all that familiar with it. So if there are any differences between the original sacred gear, and the power of my MC, I apologize.

Thank you for reading and enjoy.

Innovate clear. A perfect dimension located within the soul of a user, granting him absolute control over what is basically his own world. Even going so far as to create his own sentient life forms is not out of the question. But as this world is a completely different reality, things originating within, cannot be brought outside. Which is a pity, but ever since Kamui sensed the existence of this realm, he never treated it as a tool for battle. For him it will always remain absolutely perfect growth assistance.

When it comes to battle power, he already has Tenseigan and his own Soul Reaper abilities. His problem was not lack of fighting methods but improvement of the already existing ones. And in his eyes Innovate Clear was exactly the best way to go about it.

However as with earlier Tenseigan, despite already awakening this ability, he still doesn't have much use for it.

The seed of the Green Tree of Innovation just sprouted, and it will take a copious amount of time and even bigger amounts of Reishi to create the desired world around it.

For the time being it will remain as a little more than a decoration.

Sighing, at that fact Kamui decided to cut off the stream of Reiryoku into the bottomless hole that is his ability, instead directing it towards his Zanpakuto.

Despite it only being seven weeks since he received his blade, it already started to show some signs of individualism. First of all, the length of the blade increased, while the width lowered. Formerly plain circular Tsuba, started folding into itself, instead forming a more ornamental looking picture of a coiling dragon. Previously wooden, Tsuka started to harden and gave out the impression of smooth, yet oddly soft metal. Even the sheath of the sword started to change. It darkened and silver motifs began to appear along the length.

All in all it seemed that his Zanpakuto is a gaudy one.

While Kamui always preferred a bit of a simpler style, he found himself oddly enjoying these extravagant changes.

"Was I always lying to myself before? Maybe I always was a bit of a vain person and my Zanpakuto is trying to tell me about it?"

Coming to this profound and ultimately useless enlightenment, Kamui lowered his blade onto his hand and cut it lightly open allowing few streaks of his blood to come out and mar his sword.

It was another weird thing about his Zanpakuto. Or rather all Zanpakutos, not just his own. They are almost impossible to stain.

They repelled any dirt, and always stayed clean. All methods of cleaning the blade and a sheathe, that all Soul Reapers are required to learn, are mostly ceremonial. It's a little more than a way of showing respect and bonding with the spirit within.

But there's one exception. Blood. Or more specifically the blood of it's wielder. While the swords don't repel blood on it's own the blood also cannot stain the blade. But when the blood of the wielder makes contact with the blade, the reaction is different. Red liquid is outright Absorbed by the sword. Slowly, with relish.

When at the beginning it really creeped Kamui out; right now he stared at the process with outright fondness, feeling an ever increasing connection with the entity within.

Just as the last drop of blood disappeared, the door of the room opened, allowing its other occupant to enter.

Gin seeing the position his roommate is in, didn't interrupt him, instead going to his own bed. He assumed a similar position as Kamui, cross-legged, sword across the lap with his eyes closed. After a while of regulating his breathing, he raised his visibly shorter than usual blade and slashed it across his palm.

Just as any aspiring soul reaper at this academy, at just about this time.

"Finish! Shirato Kamui, 177 seconds."

Cursing in his mind, but not showing any outward signs of his distress, Kamui returned to his seat. It just proved the power of Gin's intuition that he realized his emotional state despite his, already legendary on the campus, poker face.

"You're slipping Kamui-kun."

"Shut up, Gin-chan, I'm not in a mood."

"What could have caused this?" He tilted his head, the insufferable smirk on his face widening. "Could it be, the bruise on your shoulder causing you more problems than you let on?"

It didn't. At least not until Gin mentioned it, causing him to flare with anger. He was a bit distracted during their regular sparring in the zanjutsu class, allowing Gin to strike a particularly heavy blow with his bamboo sword against Kamui's shoulder. And while physical pain was easy to ignore, the emotional pain that Gin scored a hit not because of his own skill, but because of Kamui's mistake, stung quite a bit.

It didn't seem like Gin knew the cause for his distress however. Well, how could he. It's not like he was aware of the reincarnator status of Kamui. Therefore he also wasn't aware that Kamui perfectly knew of the Aizen's true identity.

If he had even an inkling of that, Kamui would probably be already gone.

What proceeded was Gin attempting the exercise, and while he was considerably slower than Kamui, he improved his record by two seconds, which only upset his roommate even further.

As such when they left the class, other students gave them more space than usual, as despite Kamui's poker face his bad mood was palpable.

Actually it was partially an act. While Kamui was indeed quite upset, he figured that he should make his displeasure obvious. That would serve as a sort of an excuse in the case his behaviour was somehow different than usual around Aizen.

Even himself, with his usual 'what the hell' attitude, felt slightly nervous at the prospect of meeting the mastermind behind so many of Bleach' most resounding events. Oh. And also a future transcendent being. Can't forget that.

Surprisingly, unlike most optional classes, calligraphy, or rather as they would call it here Shodo, had its separate dedicated hall.

Although it probably shouldn't be all that surprising. After all, while this particular art for many people appeared boring, it was massively overshadowed by the fact that its lecturer was no other than Lieutenant of squad 5, Sosuke Aizen. Probably the most popular person at the Seireitei.

Thus it was normal that this class enjoyed startling popularity. People were literally crowding in the corridor, trying to catch a glimpse of the lecture, or of the lieutenant himself.

Thankfully, both Kamui and Gin found two seats within the class proper, at a surprisingly well placed location. Maybe it was a sign of respect of the other students towards two supreme geniuses of the first year; or maybe it was prearranged by Gin beforehand. It's probably irrelevant now.

In front of him, has been placed a small desk, with paper and calligraphy tools. It was a bit weird for Kamui to write with a brush, as he was used to the regular pen, and even in soul society modern conveniences like pencils and pens were introduced. Thus it will be his first try writing anything in this traditional way.

Remembering his past experiences with his absolutely atrocious handwriting, and being aware of Gin's smug grin, he gained a headache.

It didn't take long, however, until the man of the hour himself finally entered the lecture hall, causing all the students to stand up and bow respectfully.

"Welcome, Lieutenant Aizen!"

The man in question just smiled amiably, waved his hand slightly in the air, to show that he received the greeting.

"As always, thank you for the warm greeting everyone." It was ridiculous how smooth his voice was. Perfect diction, just loud enough to reach everyone, even those outside in the corridor. Yet he didn't shout, his voice barely above regular conversational level. "It's really endearing seeing such a high attendance, so many young people wishing to learn about the art that is so dear to myself. Especially seeing some new faces, as well."

His gentle gaze swept through the hall, briefly nodding to three people that were here for the first time. Kamui could swear that his eyes lingered on him for a bit longer than necessary.

"I hope everyone remembered to practice during your free time." He sat in seiza in front of his own desk at the elevated podium, after which he smiled once again at the gathering of students.

"The furthering of calligraphy in our own time above all serves self-realization by developing man's creative talents. Calligraphy frees emotions and abilities which are hidden in the depths of personality. It activates the power of the soul." 1

Kamui sighed internally, at the sound of a few female students in the back gasping in admiration, but even he had to admit that the quote sounded impressive.

"Now then. Let's warm up our tools. You must always remember to properly prepare your tools before usage. It's a lesson that will serve you well both in calligraphy as in real life."

By another wave of admiring gasps, Kamui concluded that beside him and Gin, no one caught the meaning of that statement.

But it didn't matter.

Kamui followed the procedures explained by Aizen, while preparing his tools, and somehow when his toothbrush finally touched the surface of a paper he entered an unexpected, unique meditative state.

"… the problem before us is fairly simple —To make good letters and to arrange them well" 2

Entire class, Kamui included, swiped their brushes downward. It was a very fluid, simple move reminiscent of a sword stroke.

"Calligraphy is the most direct form of all artistic expression. Just as each movement of the swordsman is absolute, so every gesture of the calligrapher is essential. It is not the meaning of the character but the writing — the movement of execution and the action itself — that is important." 3

Not breaking from his meditative state Kamui continued writing, with simple graceful movements of his wrist, his sword art gradually bleeding through and influencing his writing in mysterious ways.

"Calligraphy is about the confident gesture, the gracefully living mark made by a human being, which, unthwarted by additional parameters, speaks the universal language of the human spirit." 4

With this, Kamui completed his last stroke. After shaking off the strange state he stared unbelievingly at his paper.

Shirato Kamui.

His signature, that he wrote countless times before, was now something different entirely. Studying the strangely chaotic yet at the same time orderly characters, he felt the sensation he felt only once before. When he first spoke his name out loud, his soul resonated.

Now once again he felt as if he reaffirmed his own existence.

Unnoticed by him, or anyone else at the hall, the moment this resonans faded, massive amounts of reishi gathered, and flowed towards his soul, to the place where Innovative Clear is located.

Not only that but recalling his meditative state, and his sword-like mindset he felt as if he just achieved a small breakthrough in his ability with the blade.

He was still bewildered when Aizen's voice tore him out of his musings.

"You will never see good letters coming from your hand until you have learned to see good letters in your head. Good work depends on clear mental images. Clear images are based on knowledge of the causes of the thing imagined. Knowledge comes from intelligent practice. When practice has given the artist a clear image of what he has to do, he has insight into his art." 5

With another insightful quote, capturing the hearts and minds of his students, Aizen smiled before continuing his lecture.

It took an hour before the surprisingly insightful lesson ended.

Kamui left the lecture hall deep in thought, followed by uncharacteristically quiet Gin.

While holding a framed paper containing his signature, he was sure of one thing.

Screw the flute lessons. He will come back here next week.

Sosuke Aizen walked back from the academy towards Squad 5 barracks. He was recalling a first time seeing a new soul who caught his eye, while reading the recruitment reports.

A holder of spiritual eyes dubbed 'Byakugan'.

In the report it stated that the only ability they held was 360 x-ray vision. While this may have fooled any run out of the mill lieutenant, he knew better.

With the massive reserves of the Reiryoku the young prodigy, Shirato Kamui, at least one third of that was concentrated within his eyes. And by the look of things it was while the boy himself didn't actively use them.

It was too much of a buildup of power for such a plain ability.

Recalling also his exceptional mental and spiritual faculties, as evidenced by him easily entering meditative state during calligraphy practice; and his admittedly well deserved prodigy status, Aizen was sure of one thing.

He just stumbled upon quite an interesting little toy.

For some reason whenever I'm uploading new chapter all the formatting disappears. Whenever I go back to correct it, it's all good until I confirm the correct. Then suddenly it's all messed up again.

As I'm not that familiar with the calligraphy art, in the lecture itself I borrowed a few words from people more capable than myself.
