Kiluga

Kiluga or Kilugia (公子) is the Baronh term for prince or princess.

Etymology
In Asia the title of prince or princess is not exclusively reserved for royalty as is for Europe. They are used for children of extremely respected and important person or ministers or nobles. For example the children of a master of masters (teaching/knowledge) can have this title. In theory, it is possible for gentry to carry such a title but it's extremely rare, virtually nonexistent.
