She would never loathe you...

Purple Heart is a serious and mature person. She's often calm and rarely changes facial expressions. She is a very observant and intelligent female, thinking in a rational matter most of the time. She is the complete opposite of her human form in many aspects but her strong sense of justice and confidence remains unchanged. It can be said that Purple Heart is a bit arrogant, having a strong confidence in her abilities and believing that no one can defeat her. Despite her change in personality, there are times that where Purple Heart acts like her human form, evident when Neptune turns into Purple Heart just to ride a roller coaster.

Neptune is a happy, excitable girl with a very strong sense of justice. Her ditzy personality causes her to be very careless at times which can either help her or land her into serious trouble. She makes friends rather easily due to her friendly nature and often gives them cute nicknames. People admire her optimistic outlook and confidence. She never gives up or backs down when the going gets tough and she makes sure to see her objective through to the very end.

"No, no, no, cutie, you're not getting away...

I have so many things I want to ask you...

Isn't there anything you want to ask me...?"
