Ortho Shroud オルト・シュラウド

He is the "younger brother" of Idia Shroud and a boy devoted to his older brother, with whom he is constantly seen.

In stark contrast to Idia, he possesses a cheerful, open, and highly curious personality. He often steps in for Idia—who tends to stay shut away in his room—by attending gatherings and handling preparations for ceremonies.

These and other feats demonstrate his robotic nature, making it clear that he is—at least in his current state—not human.!~
