Hinata is indeed a dandere. Don’t believe the dumbass who 発言しました she isn’t because they haven’t searched up what a dandere is, silent to themselves, shyness to the ones they love.
In my opinion, Sakura is a Tsundere and Hinata is a Dandere. Actually Ino can also be considered as a Tsundere.I'm not able to classify guys into dere types, though. Hope this helps!
