As the walls of the Black Coffin surround me and the gravity increases exponentially by the second, I spread out my Aura and learn as much as I can about this Kido spell.
The sheer pressure of my Aura causes cracks to form all across the Coffin's walls.
Once I'm done, I retract my aura and I shatter the walls with a casual swipe of my arm.
I immediately run, causing me to disappear and then reappear in front of the Captain of the Kido Corps. I latch my hand over his face and lift him off the ground as I go through his memories and learn the finer intricacies of Kido, along with more in depth knowledge on the other ZanKenSoKi techniques.
The hand to hand combat, in the higher levels, is mostly oriented around using excessive physical strength more efficiently, which is very useful to me.
I also learn more about Shunpo (flash step), which is an extremely cool and useful technique that allows its user to move faster than the eye can see, making it appear like teleportation, which I have incidentally already done numerous times through sheer overwhelming speed.
But now that I have this technique, I can even do it to someone who has the same physical limits as myself, which is pretty awesome.
And finally, I also learn some decent Zanjutsu techniques. Even though this guy was terrible with a sword and really only had some talent for hand to hand combat and an incredible aptitude for Kido.
If I want to learn more, I guess I'll just have to observe some Captains during a fight and then subdue them to view their memories.
While watching the final memories I was interested in, I fail to notice the Captain's hand raised and pointed at my face point-blank.
I only notice when a decent amount of Spiritual Energy gathers in front of my face and it ignites into an explosive Kido spell.
I remain entirely unharmed, but quickly notice the Captain's terrible condition.
"Idiot." I mumble under my breath before I raise my index finger and point it at the Captain's chest.
I then use a healing light to heal him while his subordinates assume the worst and attack me from all directions.
I quickly release a tiny bit of my Reiatsu (Spiritual Force), in a concentrated blast around me, pushing the Shinigami back.
As the Captain is now slowly healing from his injuries, I make sure he won't wake until he's healed to avoid an incredible amount of pain and lay him down on the ground.
Done with the Shinigami, I walk inside the Academy and make a beeline straight for the library, where I immediately spread a very thin layer of Aura to cover every book and scroll as I devour them all, obtaining the knowledge contained within.
I then walk to the principal's office, where the empty Asauchi are being kept in a safe, until the new students arrive in a few weeks.
I easily break open the safe and take out a few generic looking katanas.
I use my divinity of the Forge to take one of them apart and reduce it to its base components.
All that remains is a piece of metal infused with Spiritual Energy and an empty spirit. Empty, in the sense that it has no physical form, experiences and no personality traits whatsoever, almost like a newborn.
So, only when a Shinigami wields their newly obtained Asauchi, does the Spirit begin to take shape, learn and experience. Over time, it then takes on certain traits of its master and develops a few of its own, forming a full-fledged Zanpakuto Spirit.
'Hmmm, but what about Ichigo? In his case... aargh! Let's forget about that. If I go down that particular rabbit hole, I'd be explaining and rationalizing everything I know to myself for months, before I come to the simple conclusion that Ichigo just doesn't make any sense.'
Done examining the empty Spirit, I then focus on the metal infused with Spiritual Energy. I quickly figure out that it's mostly essential to infuse the metal with Reiryoku during the forging process, but it also grants its creator, Oetsu Nimaiya, the ability to always know exactly where it is and what it's being used for.
I then have Genesis devour two of them while I do the same.
I Immediately gain all information about Zanpakuto. Their limits, their nigh unlimited potential, the methods to create amd maintain them and more.
I then have Genesis create a slab of Aegis, which I infuse with my Reiryoku. I then create an empty spirit and have Genesis make me my own Asauchi.
After a few minutes, Genesis retreats back to me as I make it form into a white version of the Shinigami outfit, like Zangetsu wears.
Left in front of me on the desk is a black Xiphos sword. A Greek, double-edged, single-handed short sword. The blade itself is only about 40 centimeters long, which was the preferred size for Spartans.
I grab the sword handle and immediately channel some Reiatsu into the blade, which quickly forms a connection and establishes me as its owner.
'I'm not going to rush this. I should just have a fight or two with the Asauchi, before I ask it for its name and unleash its Shikai.' I think to myself as I walk out of the Academy, where I notice a few familiar faces from the Anime.
Zaraki Kenpachi, the violent, battle hungry Captain of the 11th Division and his Lieutenant, the cute little Yachiru Kusajishi.
Then there's Captain Toshiro Hitsugaya of the 10th Division. The youngest Captain in the history of the Seireitei, with his Lieutenant, Rangiku Matsumoto.
And last, but not least, Sasakibe Chojiro, the Lieutenant of the 1st Division. A loyal follower of the Captain-Commander of the Gotei 13, Genryusai Shigekuni Yamamoto.
"Hoh, look at this. Two Captains and three Lieutenants just for me? Must be christmas." I say as I walk out of the Academy, sword in hand.
I take a closer look at all these 'bigshots' one by one, trying to sense their Reiryoku, using my own.
I quickly deem Rangiku Matsumoto to be no threat whatsoever. I then focus on Chojiro Sasakibe and notice the sheer amount and quality of his Reiryoku is at least triple that of Rangiku.
'How in the hell did Ichigo knock him out with one punch? That's some special kind of bullshit right there.'
I then focus on the last Lieutenant present, Yachiru Kusajishi, the little girl with pink hair who always sticks close to Zaraki Kenpachi.
I notice something off about her as I almost immediately notice the link between her and her Captain. 'She must be Zaraki's true Zanpakuto Spirit.'
'I remember Zaraki choosing to hold himself back, because he found out he was the strongest already when he was younger. He even went so far as to not learn his Zanpakuto's name, so that he could become stronger fighting others.
His Zanpakuto Spirit must have manifested itself in physical form to help him and not be trapped alone inside Zaraki's inner world forever.'
While I'm having my internal monologue, I fail to notice Yachiru squirming uncomfortably as I stare at her. "...E-Ecchi."
"Haha, you're a funny kid. But I'm happily married." I say right before an immense amount of Reiatsu weighs down on me, coming from one of the three strongest men in the Gotei 13, Zaraki Kenpachi.
I start walking towards him, while I wave my left hand to the left and then to the right, telekinetically pushing the other Shinigami away from Zaraki.
I then hold my hand down, palm facing up and as I raise my hand, a large dome barrier surrounds me and Zaraki.
"T-That's not possible! He did it single-handedly! We needed twenty Kido Corps members working together to make and maintain this!" The Kido Corps Lieutenant yells out fearfully as he gets up off the ground.
"Isn't that...?" Captain Hitsugaya starts wondering out loud.
"It's a copy of the barrier that surrounded Seireitei!" The Kido Lieutenant answers.
"Hahaha! You trapped yourself in here with me, why?" Zaraki asks with a savage grin on his face as he continuously releases waves of bloodlust and Reiatsu.
"Nah, you got it all wrong. You're trapped in here with me.
I made a few alterations to this barrier spell. Granted, it's not powerful enough to keep all the Captains out forever, but it should hold long enough for us to enjoy a nice, long, uninterrupted battle.
Oh, and a word of advice? Take off the eye-patch and use both hands. If you don't, I can't guarantee you'll live." I say, right before I unleash a bit of my own Reiatsu, creating the image of a blue, snarling wolf head behind me.
Feeling the pressure, Zaraki's grin turns into a full on smile as he immediately takes off his eye-patch, unleashing his Reiatsu, creating the image of a yellow skull behind him.
*CLANG!*
We both disappear from our positions as we meet in the middle, his Zanpakuto clashing with my Asauchi.
The impact creates an incredible shockwave, rustling up a lot of dust.
As the air clears, I'm still standing in the center of the field, while Zaraki is lying against the barrier with his Zanpakuto cut in two and a large cut across his left shoulder, all the way across his torso down to his hip.
Captain Hitsugaya looks at me intently with scrunched eyebrows while his Lieutenant looks at Zaraki, shocked at his sudden loss. "That was incredible." She says as she then focuses on me.
"I must report this to the Captain-Commander." Chojiro Sasakibe says before he uses a communication type Bakudo Kido spell.
"I told you to use two hands. You really should've listened." I say just as Zaraki loses consciousness.
I walk up to him, get down on one knee and put my hand on his shoulder. I quickly find out he doesn't know anything I didn't already know. I then use a quick pulse of healing light to stop him from dying.
I grab his Zanpakuto by the handle and hold out my other hand, telekinetically summoning the broken piece of the blade. I put it together and use a healing pulse to fix the sword.
I hold on to the sword for a second or two before looking to Yachiru with a knowing smile as I just confirmed my suspicion.
I lower the barrier, allowing Yachiru to approach her Captain. "Take care of him, Nozarashi." I say, throwing the sword to her.
"Thank you. Although it was short, I'm sure Ken-chan enjoyed the fight very much." She says, looking at Zaraki's unconscious face as he's still smiling.
I stand up and look around as a few more Captains have appeared, two of whom I'm especially interested in. Sosuke Aizen, current Captain of the 5th Division and future traitor. And then there's the main man himself, Captain-Commander of the Gotei 13, Genryusai Shigekuni Yamamoto.
