Kami, the granddaughter to the head captain Yamato. She as meant to be the next in line for head captain after he died and was always at his side. However one night out of the blue she vanished with no trace. Some speculated that she left in fear of taking on the role of head captain while others(very few) think she may have been forced out. No one knows for sure what happened but after a few decades it all faded into legend. Two hearts were left hurt and damaged by her absence: That of her grandfather who loved her as if she was his world, and That of her lover whom had given her his heart.
