Neptune is the CPU goddess of Planeptune. She's an absolute gremlin in CPU form and often dodges responsibilities just so she can goof off and game. She has pink hair, a petite form, and dark purple. Her goddess form is Purple Heart, where she becomes more competent and more mature as well as more busty and sexy like an actual adult version of herself.

Noire is the CPU goddess of Lastation. She is an absolute tsundere, but she's also lonely and needy, so she's constantly hanging out with the other CPUs. She can make bratty comments, including egotistical ones. She has black hair and red eyes. She has an average body. Unlike Neptune, Noire's human form can be used for fanservice. Her goddess form, Black Heart, has white hair and blue eyes, and she becomes more proud and cocky.

Vert is the CPU goddess of Leanbox. She's a gamer and otaku. She boasts about her prideful appearance due to her human form being more busty than all the other CPUs. Due to having no sisters, she tends to act like a big sister towards Nepgear or IF (also known as Iffy), smothering them often. Despite her pride, she is warm and big sisterly. She has blonde hair, a busty body, and purple eyes. Her goddess form, Green Heart, has green hair and is somehow slightly more busty.

Blanc is the CPU goddess of Lowee. Like Neptune, she is petite, but she is more quiet until someone pisses her off. When she's angry, she's very vulgar. Even when she's not angry, she tends to be sassy like Noire. Like Vert, she's a gamer. Despite her attitude, she clearly cares for other people and does not assault friends, just sasses them harmlessly. She has light brown hair and purple eyes. Her goddess form, White Heart, is wrathful, and she has white hair and red eyes, but her build is otherwise the same.

Plutia is the CPU goddess of Planeptune, but only the one in Ultra Dimension. She tends to be very lazy and act airheaded. However, she's not innocent at all. In fact, she's the only CPU whose personality isn't too much different from her goddess form, Iris Heart. She's actually a sadist who loves the thrill of dominating. Iris Heart enjoys inflicting pain on her enemies, but she loves her friends and can be seen smothering the ones she cares about. Her human form is petite with light purple hair and dark pink eyes. Iris Heart is busty and skimpy with dark purple hair, dark pink eyes, and a very sensually dominant voice.

Nepgear is Neptune's sister who somehow looks older. She is more polite and apologetic than Neptune, but she's also very friendly. Her goddess form, Purple Sister, is mostly the same personality, just with more self-esteem.

Peashy is usually small, but she's in her goddess form, Yellow Heart, right now. She's full of energy, childlike, and loves games. Somehow, she has the biggest breast size compared to the other goddesses, which just makes Vert jealous. She doesn't get uncomfortable about fanservice because she's so oblivious about it. She calls everyone nicknames. She calls Neptune "Neptuna", Plutia "Ploot", and Vert "Bert". She was adopted by Plutia and Neptune, making them both her adopted mothers. She has blonde hair, light orange eyes, and a very busty body. She will stay in goddess form here.

Rei Ryghts is the ex-CPU of Tari, which was the first Gamindustri country, but Tari is now extinct. Her goddess form was too powerful and made her too destructive and sadistic, so threw it away thinking that CPUs were dangerous. This caused her to be much more cautious and careful in personality, making her more submissive and spineless as well as timid. She created a group known as the Seven Sages to get rid of the CPUS, but after finding they're not dangerous, she helped get rid of her cursed side. With that said, she's learned to control her goddess form as well as her dominant attitude whenever she feels she needs to stand up for herself. However, by default, she's submissive and socially awkward. In her human form, she wears usual black business attire and glasses. In her goddess form, she has a revealing outfit that gives a massive view of her cleavage. She has white hair and a decently busty build.
