Just like many other Demon Beasts that entered and left that area, Rean and Kentucky's sudden appearance inside the monitoring formation was immediately caught. However, due to the sheer size of the area where the Demon Beasts with small concentrations of Divine Bloodlines lived, they were just two of hundreds of thousands that entered and left it every day.
That formation was made especially for races that didn't belong to the Demon Beasts. Rean and Kentucky looked exactly like them... Well, Kentucky was indeed a Demon Demon Beast, although a Regal one. In any case, they didn't raise any alarms. Rean and Kentucky looked to be at Stage Six, which wasn't anything rare here either.
