Did I mention I'm also Noragami trash?
The concept of Blighting interest me so I'm going to try to apply that to Hetalia.

He can't breathe. Thousands of voices filled his head. Fear, panic, and anger were all in his mind. The young nation opens his eyes and tries to move his purple hand. He manages to move a pinky but he also screamed in pain.

He wonders if England felt this pain before. He knew that his people were restless but he thought that was normal. It was just who he. Who they as American are, always on the go to find something new. But... why is everyone so hung up on Sl-

No, he can't even say the word. It hurts to say anything. He knows exactly what's his condition is. Even though England was an overall horrible caretaker. He still told him about how to be a healthy nation. Canada, his brother also told him about it many times. In fact years ago they were joking about it.

A nation is connected to their land as well as their people. That's why they represent the ideal person. Alfred is the "dream guy" of all the American in the land. A nation has the same mindset as the people. Every citizen has their own option but everyone has a collected ideas and desire. But if the ideas become corrupted or if the citizens are unable to come up with a solution then the nation would be stung. Normally around this time the people have already solved the problem but if they didn't,

The nation will become corrupted or for a nicer turn Blighted.

Alfred gave up to try and help himself. He closed his eyes and try to forget the pain.

It's been centuries since that incident. America made sure to never get blighted like that again. There is time where he gets stung but the mark disappears after only a day. But since Alfred was unable to get the blight treated the purple stain burned itself onto the nation's skin. When the war ended and the blight started to disappear and be replaced by the marks, Alfred covered himself with bandages quickly telling the other nation that he has gotten hurt in the war. It was a miracle that he manages to keep up with the act for thirty years. With the invention of makeup and other tools, America was able to hide his mistake away from the rest of the world.

It was a day before April first that someone found out. Before going to bed America took a shower removing all of the extra stuff on his skin. He's too tired to put on a shirt, besides no one but Tony is watching his boxer will just do. He spends the whole day doing paperwork and meetings for his boss. When is his vacation day again? 

He walked over to his bed and closed his eyes. Maybe he can get some donuts for breakfast if everything goes well. A few minutes after midnight a strange figure opens the window. The strange figure was on a mission. A funny mission if you ask his boss. His name is France and his best friend Spain had asked him to make this April Fools the best and the funniest one yet. He was done with Europe and Asia as well as his darling Matthew. All he need to do is America and he can help back home. By the time he's back the European would already found his little gift.

He watches America shift to the side, he might as well take the picture now. Even though the other nation was a heavy sleeper, France does not want to risk it. He carefully walked over and turn on the light. France almost dropped his camera in shock. The young boy was covered with blight burn as well as a couple of blights covering the back of his neck. How could he not notice this before?

Forgetting about his project, France went into the bathroom to find a big shampoo bottle. It was the remedy to blight that China had made many years ago. How old is the burn?

France carefully applies the cream to the nation's back. America groans slowly waking up due to the sudden pain. "F-France."

"I'm ashamed at you Alfred. " The older man said. "Your body is important. Why are you treating it as so?"

Alfred let out a groan as France covered one of his newest blight. "I didn't know. I thought it was phantom pain."

"Still," France said. "Did this all happened today?"

"No, the burns are s good century old."

Francis helped the other nation up. "Then talk to me about it.Blight are not just physical pain you know." 

America let out a shaky sigh as he felt the last of his current blight disappear. "It was during the civil war, I was alone and the blight started showing up." America bit his lips tracing one of the burn marks on his skin. "No one would come, I couldn't move and it hurt so much." Alfred leans on the Frenchman's arm. A few loose tears drip down to his chin. "Everyone was suffering and mad at me. Especially boss. He wanted me to fight and stop the war,"

Francis can't help but shake his hand. What is his government trying to do? If America has to fight with scars and pain like the one he has now he might as well be signing his death will.

"Are you mad at me?" 

"No, but why didn't you tell anyone, China could have treated the burn."

"I don't know. It became a habit."

France sigh, "Alright, go back to bed. I'll take care of you until you're all better."

"Alrighty. Why are you here anyway?"

"Um..Just go to sleep. I'll tell you in the morning. "

France won't be able to be there to see England face when he wear his costume. It's a shame but Alfred is first.
