Rin Shiretoko

Rin Shiretoko is the Harekaze's Navigation Officer, frequently handling the helm despite having a terrible sense of direction. Anxious and timid, she is prone to tears and stomach aches, but becomes unexpectedly energetic when trying to run away. Having spent much of her life fleeing from frightening situations, Rin chooses to pursue becoming a Blue Mermaid in an effort to change herself.
