Sand

Daughter of Rock. Like her male tone, Sand is a masculine person, and her fighting ability is high enough to compete with Yuna on an equal footing. She loves the sea, and her dream is to travel around the world while exterminating the bad guys who devastate the seas. Although she was captured by Khan, Sand was rescued with the help of Yuna, Rock and the others. After that, she vows to make her dream come true with her own power and departs with Rock and the others.
