Another Kirkland Sibling

All the countries were shocked because Arthur Kirkland (England) came into the world conference meeting with a young woman looking at about the age of 17. He told them that she was his twin sister even if it didn't seen like it to the rest of them. When the meeting progressed every single nation was flirting with her.

The mysterious nation's name was Eryn S. Kirkland (Republic of United Kingdom). She has the same temper as Arthur and she has seen all the pain and suffering her brother has experience through the years. She has tried to make him remember all the happier times when they were younger. When news of her arrival reaches the rest of the Kirkland clan it isn't good for Arthur. He tried to keep her arrival secret from their oldest brother Allistor (Scotland), their oldest sister Lynch (Ireland), her twin Seamus (Northern Ireland), the third oldest brother Dylan (Wales), and finally the youngest Kirkland Peter (Sealand). All Arthur wanted when he was just a young colony was to actually be around his sister, but that happiness was taken away fro him when he was concord by Rome. When the years went by he tried to find her, but had no success.

Will Arthur have the opportunity to see his sister without a war breaking out or will that end in a disaster?
