In episodes 7 and 8 of Selector Infected Wixoss, Akira calls Ruko and Yuzuki to an abandoned building. Akira shows them the scar that appeared on her face after her third Wixoss loss and tells them that her wish was to destroy Iona. This exchange suggests that Akira retains her memories of her experiences as a Selector.
In contrast, after Hitoe suffers three losses, she does not recognise Ruko and Yuzuki after they find her on the street. Even when she looks at her Wixoss notebook, she is unable to remember Ruko and Yuzuki. This is in accordance with Hanayo's statement that upon three losses, the Selector will lose her memories associated with being a Selector.
With this in mind, why does Akira retain her memories? Perhaps Hanayo's explanation of the loss penalties was incomplete?
