Both Binan Koukou and Go! Princess Pretty Cure have a name of a son/daughter of the monarch, which is 'prince' and 'princess' respectively in their roll call upon transformation.
Both protagonist (Hana and Luke) are involved in love and in the middle of the story, they decided to cut their hair short to change themselves into a better person.
They are both in Pretty Cure Series, some storyline is both the same, but different theme and character. Also, in the movie, only the leader gets the upgraded form. If you ever watch Fresh and/or Suite Pretty Cure before, you will know what is the same.
