She used to be a cute girl. She has grown to wear glasses.
When she was a child, she was loved by Satoru, who was however too shy and ended up playing a prank on her by making her wear a necklace made of sea shells from garbage. She would receive a proper shell necklace from him after he died drowning, and picked up every shell necklace he continuously made while lingering at the beach, that would wash up on shore and put them on sale.
She remained at the beach and works as manager of an inn called “The Sea House Seashell Inn” (海の家 貝がら荘).
