Sixteen years ago in Japan, on April 7, two children where born. A son and daughter. They lived with each other and their parents for a year, but due to complications, the parents where forced to make a decision to let one of their children be taken away to a foster home in America. It was a tough decision for them, but it was done for the better to let their daughter go.

Seven years later, the parents moved to Mexico with their son in hopes to find the missing sibling. But before the parents could tell their only son that there was another child to the family, his long lost sister, they passed away, leaving their 8 year old son to the grandfather of the family.

Five more years pass while living in Mexico. The boy who was now 13, decided it was time for him to move, since there was no one else to take care of him. His grandfather had sadly passed away.

Now, just about three years later, he is now in 11th grade and has just turned sixteen. He lives in the town of Karakura and lives by himself. But little did he know, this birthday of his was more than just him getting a year older.
