After Azazel, who was overjoyed because of both the cheesesticks and his newfound knowledge, left the store, it went quiet for a while. Not the bad kind of quiet, but rather a comfortable quiet with the sound of rustling books in the background. It was a very relaxing moment. A moment Rei used, to check what ability he gained from this times guest.
'Turns out I received experience... Neat! Who wouldn't want the experiences of a powerfull being with an age of several thousand years?'
As soon as the experiences were assimilated, Rei felt way more... well, experienced, than before. (A/N: Well, Duh! I just didn't know how else to describe it.) He suddenly knew all about war and peace times, strategies, diplomacy etc. It was... strange, to say the least. Not the bad kind of strange, mind you.
When he was done checking his newly gained experiences, Rei opened his eyes again and went back behind the counter. And just after he came to a stop, the door opened once again.
Inside came a tall white man with blond, dishaveled hair, wearing getas a yukata with an open, black overcoat and a green and white striped hat, holding a wooden cane. He seemed to be relaxed and easy-going, but thanks to Rei's sensibility gained by cultivating and the experiences gained from Azazel, he quite easily recognized the mans eyes. Those were the eyes of someone, who is carefull and preparing for an ambush.
Once Rei saw this man, he immediately knew, just who he was. Urahara Kisuke, former commander of the twelfth squad of soul society's Gotei 13, now renegade Shinigami and owner of Urahara Shop. One of, if not the brightest mind and best researcher concerning soul-related matters in his entire world, a true genius, though a bit deranged sometimes.
"Welcome to the Akashik Cafè, Urahara Kisuke-san. It is a pleasure to meet you. My name is Rei Suzuki, the owner and only clerk in this shop."
"Mhmm... So, where and what exactly is this place? 'Cause I cant seem to locate my position."
While saying this, he became a bit more serious.
"Of course you can't. If you could, you'd have to be One of the strongest Primordials there are, or a Concept. But to answer your question, we are currently outside of all verses and dimensions, in an entirely different dimension, containing only my shop and connecting it to all the different verses, timelines, worlds and dimensions."
"Outside of all that, huh. Well, I certainly am unable to detect that kind of place. By the way, what are those Primordials or Concepts you're talking about? And why am I here? What kind of shop is this? General Rundown please!"
"Very well. Primordials are the second strongest kind of existences, which are almost omnipotent and pretty much completely immortal. Concepts are the personifications of, you guessed it, concepts. Like Life, Death or certain Emotions. It can even be something like time, space or the void. And before you ask, yes I will now give you the rough classifications.
First there are Mortals, basically your worlds normal humans and animals. No special powers, no super strength, nothing.
Second are Supernaturals. These are basically all beings with special powers, be they learned, inherited or received. They generally have at most the power to destroy a city or two.
Third are Immortals, where supernaturals become strong enought to lose the concepts of age and lifespan, not becoming all that stronger. Instead, they learn to find themselves and accept it, becoming one with themselves, gaining complete control over their entire being.
Fourth are Demigods and Demigoddesses. They are way stronger than other immortals, to the degree, where they can reshape the land with a simple spar. Since they begin building their divinity, gained mostly by the worship or faith of other beings, in this phase, although unconciously, they begin transforming their body into energy, making it near indestructible because of constant regeneration and conversion into energy. This causes them to overcome their limiters without bringing harm to themselves.
Fifth are low rank gods and goddesses, which consist completely out of energy and have built their own divinity. They are more inclined to act according to their divinity and become truly immortal towards anything of lower rank than themselves, as divine energy is needed to destroy a god or goddess completely, with no chance of regenerating. In return all beings who gained their divinity through faith, which are 99.9% of divine beings, are dependant on said faith, boosting or limiting their strength. Their strength and abilities, sometimes even their appearance, differ according to their divinity, though most of them like to take on humanoid forms. This goes for all beings with divinity. Low rank divine beings cannot leave their world to, or interact with, different worlds and dimensions, not to mention universes.
Sixth are mid rank divine beings, who are basically just strengthened low rank divine beings with the ability to travel to and interact with other worlds, thought still not other dimensions or universes.
Seventh are high rank divine beings. Same thing as mid ranks, just more powerfull and with the extra ability to interfere with dimensions.
Eigth are the peak ranks and highest a mortal can reach without possessing the bloodline of a primordial or the permission and blessing of the highest ranked being. Tey are, again, more powerfull that high ranks and can interfere with universes. At this stage they become intependant from faith of believers.
Above them, on the ninth rank, are Primordials and Concepts. They are, as said, almost completely immortal and omnipotent, also gaining complete dominion over their chosen field. They also gain the ability to traverse different multiverses. The only way to become one of them, is through being born as one or becoming one by the highest existences powers.
And lastly, at the highest rank, we have The Original. The very first being to come into existence. Omnipotent, Omniscient, and pretty much Omnipresent. Though it can choose whether it wants to be all that or not. The origin of all of existence.
But, back to your other questions, this is a multiversal Bookcafè, directly connected to the Akashik Records. You were able to come her, because you have a thirst or need for knowledge and are not an inherently bad person. In here you can potentially learn everything you wish for, though I had to place some restrictions. For example, you won't receive any eldritch texts, as those would make anyone below the divine ranks go insane immediately. You also won't receive any world or soul destroying knowledge. And by soul I don't mean your shinigami form kind of soul, but your pure soul, no power, knowledge or personality. When you guys kill something in soulform, you just send it to the reincarnation cycle to become a blank slate, no matter what you do with what you call the soulbody. None other than mid rank divine beings and above can interact with or even see the true souls of beings after all."
"That... was a lot of new information to take in..."
