A young hero travelling around the seas of the world, training to become stronger. Blue had an older brother. His name was "Brutus". Brutus taught Blue many skills and always took good care of him. They vowed to each other that they would get stronger and train together...But Brutus started meddling with the "Forbidden Arts" that had been passed down by his tribe. He was banished from his tribe and he disappeared into the darkness of the sea. Blue did not understand why Brutus would go that far in order to gain strength. His tribe resorted to calling Brutus a "traitor", but Blue still believed in him
"They all badmouth my brother...but I don't agree. I love my brother!"
"I want to fight with Brutus again some day. Until that day, I will train to become stronger!"
Believing that he would one day meet Brutus again, Blue trained hard
