I'm sorry this took so long everyone I had a weekend writer's block. I hope you enjoy anyway.
Kakashi looked around at everyone in the pub. Some were staring at him and others were avoiding his gaze. Kakashi expected this but was discouraged anyway. This moment was much too similar to the before when he was younger and trying to get away from the White Fang's failure. He inwardly shuddered at the memory of his father and shoved the memory into the back of his mind, where most of his past tended to be. He had to keep his cool composure, especially now in this different world. He knew very well how important first impressions were and wanted to at least seem respectable. Kakashi stood and looked around more, trying to find the next representative. He scanned the room until his eyes stopped on a rather large person. He was an enormous giant standing in the doorway and slouching a little so his head wouldn't hit the ceiling. Kakashi tried to look read his face but most of it was covered in wild and shaggy black hair. Shinning black eyes stared curiously back at his own dull black eyes. Kakashi held the eye contact until the giant looked down and muttered something. He shuffled over to Kakashi and Minerva; waving his hand in a friendly greeting.
" Professor, I see yeh brought ar' guest wit yeah, my name's Rubeus Hagrid, Keeper of Keys and grounds and Care o' Magical Creatures teacher a' 'ogwarts." He stuck out his giant hand and grabbed Kakashi's arm. He shook it furiously while beaming down at Kakashi's shocked face.
"H-how do you do Hagrid-san; you can call me Wolf" Kakashi said while tearing his arm away from Hagrid's grip. He returned his face into the bored and blank stare that he usually wore and crossed his arms. He gazed questionably at Hagrid's pink umbrella; not even paying attention to Hagrid's rambling about how nice the weather was today. Kakashi returned to the conversation when Harry Potter was mentioned. He supposedly blew up his aunt like a balloon from anger and left his aunt and uncle's home on a Knight Bus. Kakashi rolled his eyes; none of it made any sense to him but he could tell that Harry was as much of a spoiled brat as he originally thought.
"Excuse me McGonagall-san but I believe Hagrid-san needs to take me somewhere." Kakashi said with mock courtesy.
"O yeah I almost forgot! Are yeh ready ter go Wolf? Kakashi nodded and Hagrid then proceeded to search his many pockets pulling out random things like a teacup, a mousetrap, and jumbo dog treats. He finally found what he was looking for and pulled out a piece of parchment that looked like a shopping list. Hagrid said his goodbyes to Minerva and shuffled toward the back door of the pub. He waved to Kakashi signaling Kakashi to follow him. They proceeded out the door and stopped in front of a brick wall. Hagrid stepped forward and begin to tap the bricks in a pattern with his pink umbrella. Kakashi stared in amazement as the bricks began to move on their own and created a doorway to a street lined with shops.
"What is this place Hagrid-san?" Kakashi asked. Hagrid just laughed and replied, "This is Diagon Alley Wolf. This is where most wizards get all of their supplies. It's the perfect place to get all of your new school supplies."
"I don't anymore supplies. I brought my all that I need from home." Kakashi added. He glared at Hagrid and crossed his arms, stating that was not going to budge. He was practically pulled into one of the stores by Hagrid. He started to protest again but was pushed up to the register. Hagrid rang the bell for him and an old strange looking man came out of a back room.
"It's good to see you Hagrid. Who have you got with you today, another star in the making perhaps?" The old man shook Hagrid's enormous hand and circled Kakashi sizing him up. After he finished he asked, "This one's a bit older than usual Hagrid. Never the less we will find the perfect wand for you boy. What's your name son?"
"Wolf." Kakashi stated. He was starting to get annoyed by the man and just wanted this 'shopping trip' to be over with.
"That's quite a strange name you have Wolf. I'll be right back with the first wand." The old man hurried excitedly to the back wall that was lined with small boxes. He pulled out a small olive green box and gently pulled out an embroidered stick out of the box. He placed the stick in Kakashi's hand took a step back.
"Try this one, willow 11 and ½ inches, dragon heartstring. Go ahead Wolf wave it and see if the wand picks you." The old man urged. Feeling stupid, Kakashi waved the stick and nothing happened. Kakashi decided to take a risk and pooled a little of his chakra into the stick. It started vibrating in his hand and grew expectantly hot. Kakashi dropped it fearing it would burn his hand and the wand exploded. The old man muttered something about the wrong wand and ventured back to get another box.
"Try this one, Birch 11 inches, unicorn hair." The old man handed Kakashi another stick and he poured chakra in the new 'wand'. The books and papers in the room flew around until the old man grabbed the wand from Kakashi's hand and put it back in the box. Wand after wand was rejected by Kakashi but the old man's face grew more and more excited as each wand was rejected. He climbed to the top of the wall of wands and grabbed a bright red box that was extremely dusty.
"Try this one Wolf; it's one of my rarest and most powerful wands." He handed Kakashi the wand and watched in excitement. Kakashi poured more chakra into the wand expecting there to be another explosion. Instead, the wand grew pleasantly warm and emitted jets of green and gold light. Kakashi had finally found his wand. Hagrid and the old man clapped their hands for Kakashi's success.
"I knew it would work! Vine wood, 10 and ¼ inches, Hippogriff talon!" The old man seemed very excited now.
"Excuse me, but why are hippogriff talons rare and powerful?" Kakashi couldn't help but ask.
"The hippogriff talon wand is rare because you can only get a talon from a dead hippogriff and it's powerful because the wand is like a hippogriff. It is normally a touchy wand that demands respect and in turn is very good at protecting spells for its master. The wand also reflects its master. That means that you are a person that wants to be respected and should be respected. That will be 20 sickles Hagrid."
Hagrid happily paid the man as he led Kakashi out of the store. Kakashi clutched this new wand. It wanted Kakashi to protect everyone too. He sighed knowing that his wand was just another thing that he would end up disappointing.
I decided to go with a hippogriff wand core just because it sounded more like Kakashi's personality, and the vine wood is the celtic wood for Kakashi's birthday(September 15) I believe J.K. Rowling used the celtic woods for Harry, Ron, and Hermoine's wands too.
