Selectors are chosen female card players who compete with each other through the card game called WIXOSS. Along with them are their respective LRIGs, talking cards who can grant them their wishes by winning battles and fulfilling other requirements. By fulfilling all of these, they become Eternal Girls.
The Chosen One: Once a girl meets her LRIG for the first time, she becomes a Selector.
Estrogen Brigade: An In-Universe example. While the card game is targeted towards females, there are male players. However, only the females can become Selectors.
Driven to Madness: Apparently, the card game can lead the Selectors to their obsession of having to seek and battle others just so they can fulfill their innermost wishes. Of course, this has cost them everyone and everything around them, which later would be their downfall. Akira and Yuzuki are the most notable ones.
Foil: Some of the relationships between Selectors and LRIGs have this.
Iona herself is a dedicated Blood Knight who could care less about her own idol career and wants to battle strong opponents forever.
Voiced by: Ai Kakuma
Blood Knight: Starts to realize that she really enjoys Selector battles. She feels terrible about it, as she doesn't want to get in the way of other Selectors' wishes since she doesn't have a wish herself. She starts to enjoy it again in her match with Iona in Episode 7.
Friendless Background: Prior to meeting Yuzuki, Kazuki, and Hitoe, she never made any friends nor did she ever care to.
Hair Decorations: A red diamond-shaped scrunchie which she uses to tie a side ponytail. This is substituted by a light blue scrunchie later in the series.
Heroic BSOD: After learning the dark nature of the card game and the pain of other Selectors, she can't help but think and cry about them. Not to mention that she has lost two of her friends because of the game.
Expy: Of Sayaka Miki. Like Sayaka, Yuzuki is the perky best friend of the rather meek lead, has to struggle with unreciprocated romantic feelings, and is the first example shown of what eventually will happen to the girls.
Grand Theft Me: Her grand prize for becoming an Eternal Girl? Becoming a LRIG while Hanayo takes over her body.
Despair Event Horizon: Almost crosses this. After becoming Hitoe's LRIG, she attempts to motivate her to win her battles so she can hijack her body and reunite with Kazuki. Though after learning that Hitoe's wish is still the same, she gives up on it and tells her and Ruko about everything she discovered during her meeting with Mayu.
Cute Bookworm: Very adorable and one of her favorite places was the library.
Color-Coded for Your Convenience: She has a green card deck. Following her loss to Iona, she loses this along with Midoriko. A few episodes later, her mother buys her a new red deck that contains Yuzuki as her new LRIG.
Expy: Of Yomi Takanashi, especially the part where they lost all of their friends mid-season. They get better in the end.
After losing her third game, her wish to make friends becomes tainted in the form of painful shocks whenever someone with any kind of positive affections touches her, meaning she will never make any friends forever, but this gets reversed after episode 12.
Interestingly, she was able to be touched multiple times by Ruko without any negative effects after Yuzuki became her LRIG, meaning that her wish being tainted was likely undone.
Mind Rape: After losing three games, she loses all her memories of her friendship with Ruko and Yuzuki, and becomes more timid and socially anxious than ever, to the extent that she finds just walking in a crowded area mind-numbingly terrifying.
Mini-Boss: She's the last opponent Ruko fights before Iona.
She's Back: After receiving a new red deck with Yuzuki as her LRIG, she becomes a Selector again. She also regains her memories after battling Ruko again.
Curb-Stomp Battle: Her strategy to have her wish fulfilled and become an Eternal Girl more quickly. She seeks less experienced Selectors like Yuzuki and Ruko and mind rapes them with her LRIG to gain cheap victories. Inverted in the case of the latter as Ruko beats her easily.
No Sympathy: Aki is not bothered by the fact that Hitoe is forever unable to feel any love or Iona's near murder of a Selector.
Lack of Empathy: She's not even bothered that she was the one who caused that murder.
Mind Rape: How she gets easy wins. She commands Piriluk to read her opponents' wish and taunts them about it.
Unreliable Expositor: Before her battle with Ruko, Akira tells her that Iona gave an ill Selector her third loss, tainting her wish and possibly killing her in the process. It is revealed by Iona's LRIG Urisu that Akira was the one who did all that, with Iona giving that girl her second loss beforehand.
Scars Are Forever: She deliberately cuts herself in the face with a knife after losing to Iona.
Kick the Dog: Iona essentially killed a girl who was on her last legs by beating her in a WIXOSS battle and tainting the girl's wish. If Akira's testimony is any indication, it wasn't that hard to tell the girl was terribly sick, but Iona let her die anyway without regrets. In reality, she gave that girl her second loss before Akira put her out of her misery.
She is also responsible for giving Hitoe's third loss and subsequently tainting her wish of making friends.
Only the Chosen May Wield: Her wish. In a twist, she is looking for a Selector who is worthy enough to wield her. As in, when she becomes a LRIG, that Selector will own her. She has chosen Ruko and she gets her wish in the the first season's finale.
Ascended Extra: While she is seen in the first season's opening credits and some promotional artworks, she only appears in an episode where she is defeated by Yuzuki. Obviously, she will appear more in the upcoming second season.
LRIGs are talking cards and the Selectors' main companions. Only the Selectors can hear them and like them, they are all females. They have the ability to grant them their wishes but first, they must complete certain conditions.However, they are not allowed to tell their Selectors the full details of the card game, especially the Eternal Girl part. In fact, they are the Eternal Girls. Eternal Girls are former Selectors who managed to win their battles and fulfill all the the requirements of becoming one. Once they ascend to the Eternal Girl ritual, their LRIGs takes over their bodies and their wishes. Later, they themselves become LRIGs and they are sent to would-be Selectors. This cycle continues in order for the world of WIXOSS to exist.
Eternal Recurrence: How the Eternal Girl thing plays out. Once a Selector becomes an Eternal Girl, her LRIG takes over her body and her wish and she herself takes over the role of her LRIG. The new LRIG will then be sent to another Selector to be hers and the process continues.
Grand Theft Me: The LRIG will take over the winning Selector's body and wish. The Selector is then turned into a LRIG and she is sent to another Selector.
