As long as you're leveled and gear up, you can generally clear any content with a decent healer, that being Althea.
I cleared campaign 1 and hard mode with Suzume, Helen, Althea and Coral, all normal rarity girls. I've been lazy with campaign 2 but I'm sure you probably could too after leveling them to 75. Though my party now is completely different aside from Althea.
