Muir Castrea

Muir Castrea is the foster daughter of Arnold Ocean and was one of Hiiro Okamura's first traveling companions. She went from admiring Hiiro like a big brother to developing much deeper feelings. She has vowed to get stronger. But she is unable to believe in herself. She spent her days doubting whether or not she will even be able to influence her own life. To her, fighting is scary and being protected makes her feel relieved. But still, there are people she believes in.
