Now we come to the easiest to review of the Precure series.

Heartcatch can be described as the series that went from A rank to S rank in terms of popularity and it's not difficult to see why.
In a change of pace our pink Precure leader Tsubomi is not a genki girl but a shy introvert making her unique among the other lead cures and her interactions with the others builds her up as one of the best leaders.
Erika is now the genki girl and while she's not much different to other genki characters, her saving grace is that she pairs well with introvert Tsubomi so their friendship dynamic is stronger.
Itsuki is the princely girl character, raised as a boy, has a desire to be more feminine, these character traits rarely disappoint and Itsuki is no exception, she also has the best transformation so far in the franchise.
Then there's Yuri.... she's so well written it's unbelievable that she came from Precure; up to this series, Precure kept a fairly samy set of plot lines and going more serious is rare but not only does her backstory give her more dimensions and set the standard future seasons needed to achieve, it gave a better understanding of the Precure mythology as a whole.
