Tohka
Because Tohka is new to everything (including her emotions), she has a very cheerful and child-like personality that can make her seem naïve, emotional, energetic, and gullible at times. She easily became excited at seeing all the things on Earth that she had never seen before. Origami has used her naïve nature against her on multiple occasions. She usually needs one of her friends (mostly Shido) to point out to her when she is being tricked.

Kotori
according to the color of the ribbons she's wearing. While wearing white ribbons she is that of her "weak self", a delicate little sister who is very dependent upon her big brother; and when wearing black ribbons, she becomes her "strong self", a charismatic and sometimes cynical leader able to successfully command the airship, Fraxinus. According to Reine, the Kotori with white ribbons is the one that can honestly say how she feels, which would mean that the Kotori with black ribbons is only putting a strong front because the situation requires so.

Origami
Origami is a person that rarely openly talks with other people unless needed with only a few exceptions such as Shido and Tohka. She isn't a shy person, but more of an unsocial type of girl.
She can be a bit reckless or aggressive if she has a goal or purpose to fulfill; she's also willing to do something that someone else wouldn't do to accomplish such goals. This determination is shown when she did everything Shido asked of her when he was trying to get her to not like him which shocked everyone around her.

Yoshino
Yoshino is described as a shy yet kind little child and is far more passive than the other spirits. She possesses two personalities: Yoshino and "Yoshinon". "Yoshinon" is Yoshino's alter ego that appears in the form of a puppet speaking through ventriloquism and was created to help her bear the hardships of being hunted by the AST. Since Yoshinon was created based on Yoshino's ideal hero, the puppet often expresses more an outgoing and outlandish demeanor when speaking. The Yoshinon personality only exists within the puppet, when the two are separated this personality becomes dormant. This is why Yoshinon doesn't understand what ventriloquism is as the puppet believes it is alive.

Kurumi
Kurumi is a person whose character is difficult to read. She possesses a dislike of humanity that borders on mistrust, which is something that she shares with most of the other Spirits in her debut. She is a skilled actress, capable of putting on the façade of an innocent, curious young girl when she needs to. This skill of hers is shown when she registered as a student at Raizen High School and spoke in a polite manner. However, under that mask lies a mad woman, prone to fits of insane laughter and possessing no regard for human life, viewing them as a food source to restore her own time, and thus, a disposable commodity.

Author's Notes- Yes I've decided to do this. Other girls will be added later but this is it for now. Because I'm lazy I got their personalities from Wikia because otherwise I'd have to watch it all over again. Not that I wouldn't I just don't have time. This will rely on votes and not the little star ones I mean I will make you vote on what course of action will be taken so in that manner it will be interactive. Zenith Out...
