why do آپ think princess آڑو is the main princess?

Because she is pretty and girly and better than daisy

because nintendo made her before گلبہار, گل داؤدی یا rosalina and plus she the princess of the مشروم, کھنبی kingdom :)

because she has mario who rescues her about each day.

Because Shigeru Miyamoto created Princess آڑو to be a part of the main cast.

گلبہار, گل داؤدی doesn't get the same luxury because Super Mario Land was made without Miyamoto's knowledge. (Or so I was told.)
