Lina

The young girl infiltrated the Spa Island and began living together with the sea tanuki, Nukky. At first, she disliked her father, who had left three years earlier on a research journey, but an incident caused her to change her mind. A few days later, Lina took a hint from the order of colors in a rainbow and succeeded in completing the gemstone research that her father had been working on. Lina's father's voice is provided by Ryusei Nakao.
