There isn't really any other way to get crowns, just:

Complete a quest for the first time

Get them from an event

Login rewards

Random celebration gifts from Silicon Studio

And buying them with real money

Have you completed the bonus areas (the ones opened when you use the brave aura purification option), maybe you missed those crowns.
