The precure manga's have all been horrible so far. Why you ask? Because the lack of the important support characters. And the story feels very rush due to the small amount of chapters they have, leaving no development for the support characters and main character, having no bond with them, making the final arc boring and lame.
The lack of Momoka in this manga is seriously offensive, the most important side character that has a true bond with Yuri and Erika to show herself only twice! (One time with her looking like a self insert doujin main character!), makes me very upset. This manga could've been
the best of the Precure franchise, due to its anime already being amazing, but no, it has to forget its most important support character! There was too much focus on Itsuki and not on Momoka, who is in fact, way more important than her, for being Erika's sister and the reason why Erika has troubles that she faced and grew with. And we cannot forget the fact that she is in fact dating Yuri!!!! (Screw you Hayato!) how could we ignore such an important support character? What's the point of being called a support character when they can't support the ones that need it?!
