Barairo no Tenshi

In ancient times, a peaceful island was disturbed by the landing of foreigners from a more advanced civilization. The two groups seemed to coexist peacefully, and gave the chance for the young sculptor Palos and the beautiful Rota to meet and establish a tender relationship. But the ambitions of the court soothsayer and the arrival of a mysterious comet will turn the situation upside down.
