I don't think Hinata belongs in this picture, truly. She's not the stoic/emotionless personality type. Quite the contrary.

I think the idea is more that they looks similar... or, well, at least Hinata used to. Now, not so much.

maybe if an Emotionless shell bite you maybe you turn into one. ya know like a vampire that drinks out your emotions.

however they're my 3 favorite girls

adorable girls you just want to hug, with short hair, and those very emotional eyes that are not all that normal?

I think this is more around the lines of the "girls that most people would like to see be with the lead male character but probably will never happen"
