The Bidau Family is one of the 10 Great Families. Its members are most likely proficient in the use of Shinsoo, as their leader, Po Bidau Gustang, is an expert in handling Shinsoo with great accuracy.
The males of Gustang’s family work in a research group called the Research Association. If they do not make it as members, they are eventually kicked out of the family. Because it is a very powerful and exclusive group, the members enjoy high reputation and fame, matched only by the "Chosen children of Koon".
