So I come into this Precure thinking we have lost some luster as I consider Doki Doki to have the weakest team.

Mana can be best described as a steam train trying to be the ultimate helpful girl; her ambitions are noble and it reflects in her precure form but my god slow down.
Rikka is just the poor sap who has to play caretaker to the hyperactive Mana and practically has no personality that hasn't already been done to death by now, she brings nothing new to the table and is way too generic to be a proper precure, worst precure so far.
Alice is the precure equivalent of Batman, she's insanely rich and uses it for her hero activities, and has an insane temper for a shorter girl, probably the best of the team in terms of personality.
Makoto doesn't sit well with me, her royal guard act strikes me as trying too hard to be a strong character but doesn't really mix well with her idol persona nor her attempts at understanding the human realm.
Aguri is the hardest precure to rank overall, her role as a super cure creates conflicting opinions, is she a badly needed mentor cure to the current team or is she a deus ex machina that renders the others useless and her so called time limit also feels very shoe horned in to justify her staying on equal levels with the other cures. In my mind if she's making me think this much then she's a good character.

Aida Mana - Cure Heart - 7.4/10

Best Dressed Award - Cure Ace, not the best team for costumes.
