Modern American invention, likely a blend of Bre and Asia
Breasia is a contemporary American name created by combining the popular prefix 'Bre-' (from names like Brianna or Breanna) with the name of the continent 'Asia'. It emerged in the late 20th century as part of a trend of rhythmic, multi-syllabic feminine names. Because it is a modern creation, it lacks a singular historical etymology beyond its component parts.
