Youngest son of Mangetsu's quartet of children. Shingetsu shares an appearance with Sarama. At a young age, both he and Sarama were often bullied. Shingetsu was often singled out for his ability to learn any attack or spell he has witnessed at least once, mainly because others thought he was cheating. At the age of 10, Shingetsu was chosen by the Seraphim Blade over his elder brother Carth to become the next Guardian of Destiny, like his father before him.
