I think I'm finally getting over my writer's block ^-^ Hurray. Still, I was comtemplating last night as I was falling asleep what should happen to the Hetalians :D So then, I fell asleep and forgot T.T then remembered...then forgot...then I finally remembered and could type it down, though it might not be that good of a chapter -.-

England POV

England was only unconcious for a few seconds. When he came to, he noticed everyone was younger. Good. The spell did it's job correctly. "Veh, Germany, look, I'm a little country again!" Italy exclaimed with joy...as usual. " Ja, I see that," Germany replied. "Get away from-a my younger brother, you damn potato bastard," Romano said. "I haven't been this young in four thousand year," China said. (I'm too lazy to look up how old China is so I'm just guessing...-.-) "ohonhonhon, Italy is so cute," France laughed pervertedly. "DUDE, I'm young and I'm STILL a HERO!" America boasted. That noisy wanker. "Alright, alright. That's enough. I hope we can still buy our supplies without an 'adult'," England mused,"That was why I wanted us to go as adults and not children. I suppose it can't be helped. Let's go," England unlocked the door and stepped out, followed by the other counties. They had almost made it to the back door before America noticed all the attention that one black haired boy was getting.
"Hey, why is HE getting all the attention?" America asked loudly. This caught everyone's attention. "Alfred," England warned.
"I'M the hero, so why doesn't anyone want to shake MY hand, like they are doing to him?" God, America is stubborn. "Alfred, Let's go. We need to get our supplies TODAY, you know," 'Why am I even trying to convince him? He's a stubborn brat who never listens,' "I mean come on. He's just a little kid. He can't be a hero!" (yes yes ik. Refer to paragraph one lines 3 and 4) "Idiot. Have you forgotten you're a kid as well?" England grabbed the back of Alfred's shirt and hauled him outside. There, they were surrounded by brick walls and everyone only just barely fit inside the small space. "You wanker! What were you thinking? That's the boy we have to become FRIENDS with, not enemies!" England sighed. He looked up at the brick wall in front of him. "Oh no! I forgot we don't have wands yet! What are we going to do now?"
Just then, a VERY large man sqeezed into the tight space with the black haired boy behind him.
"Yah need help?" he asked on a gruff voice. Everyone nodded. "Alfred, apologize to that boy," England said sternly. "Oh, but why?" he whined. God he is such a child. "Just do it, Alfred!" Alfred turned to the boy, "I'm sorry," he said quickly, then turned away. "For-?" England pressed. "For...insulting you?" England nodded. America's pride may have just been hurt, but he need to learn some manners. When England turned around, the large man had somehow made the brick wall disappear.
"So are you all foreign?" The boy asked China, who nodded. "Aren't there magic schools in your countries?" "We are doing a cultural exchange this year, the headmaster of Hogwarts asked each country to send a representative first year to attend Hogwarts for a year or so. We all just happen to know each other, right, Arthur-san?" Japan explained. (I am not going to write in Japan's accent, it is too confusing for sounds awesome though. Also I'm not sure if I used the right honorifics.)"Right,"England agreed. "We will see you later," England dragged the Hetalians to a nearby store after saying good-bye to the boy. The store was Ollivander's, which was packed with rectangular boxes and random wands strewn everywhere. "Erm...hello?" England called. Suddenly, a latter appeared and a man-presumably Ollivander- with shocking white hair appeared on top of it. "Ah, customers. Sure is busy today. Who are we going to start with?" Before England could open his mouth, America stepped up,"ME! 'Cause I'm the HERO!" Ollivander snapped his fingers and a measuring tape started measuring (DUH!) Alfred while Ollivander searched his shelf. He pulled out a thin white box and gave it to Alfred (The taped stopped measuring), who opened the box and pulled out a thin, brown wand. "13 inches, Oak, eagle feather core, give it a wave," Alfred waved it and his flag appeared in sparks, eventually disappearing. This happened to all of them, though some had to try a few more times than others.
Alfred:13 inches,sycamore, bald eagle feather core

Arthur: 11 inches, oak, lion heartstring core

Matthew: 8 inches, maple, beaver hair core

Feliciano: 12 inches, elm, italian wolf heartstring

Lovino:11 inches, olive, blue bird feather

Ludwig: 15 inches, horse chestnut, black eagle feather

Yao: 10 inches, Gingko, panda heartstring core

Francis: 14 inches, Yew, Galliec rooster tail feather core

Ivan: 12 inches, white birch, russian brown bear heartstring

Kiku: 9 inches, cherry, green pheasant head feather core

Toris: 7 inches, rue, stork feather core

Felix: 15 inches, oak, white-tailed eagle feather core (Ugh that took me forever o.0 what sucks is I was doing national symbols, but then I realized that America and Poland's national animals were similar, and Poland and England and America AND Germany have the same national tree, so I changed America's to Sycamore and Germany's to horse chestnut -.- Also, it seems as if Japan doesn't have a national animal, so I did the closest thing.)

A few hours later, the shopping was done, and everyone was tired. England kept everyone's wands and supplies until September 1 came. After everyone left, England relaxed. Now that he was younger, he could barely see over his huge stash of paperwork. 'Well,' England said to himself,' better get to work,'.

YAY this one was a bit longer. Only because of the wand descriptions Next chapter will be "King's Cross Station and The Train Ride"
