Huh? Kishi has stated that Hinata may have been a better heroine in an interview
Actually no.The interviewer asked him that fans thought Hinata was a better heroine and then Kishi replied
"Honestly, from the standpoint of showing a female-like disposition, she hasn’t been much of a heroine. You could even say that Hinata’s more of a heroine than her. But since, as we know, Sakura is a heroine deep inside, she’ll show that side of hers from now on.”
Interviewer: "Because of this, she acted quite haughty towards that guy. She used Naruto’s love for her and told him she loved him."
Kishimoto: "On the contrary…. I felt like depicting an honest girl, with a surprisingly stubborn impression.”
And Kishimoto also comments:
"So... she became such a character, but... well... from here on, maybe I should draw her showing a bit more spirit.
I figured I had placed her in a heroine-like situation
But from the readers I was told harshly that she wasn't heroine-ish at all
Perhaps I should show depict her a bit more like a heroine
Because you say 'Hinata Hinata,' I say 'She's not Hinata'"
