When they were children, Gwen and Ben were not very friendly to each other, constantly arguing and bickering like siblings. Deep down though, they cared about each other greatly. In the present day, they are each other's favorite cousins, as shown when Gwen and Ben had a tearful reunion in Las Noches.
Despite the rocky start to their friendship due to her revealing Resurrecion, and because of Gwen's fears that the Arrancar were simply using Ben as a form of enjoyment, Gwen is very grateful to the former Tercera Espada, as, alongside her Fraccion and Nelliel, she has managed to make Ben happy again after he and Julie broke up, and gets along well with her.
Nelliel Tu OdelschwanckEdit
Hachigen Ushoda Edit
Gwen is friendly to Hachigen, and showed interest in his offer to teach her how to use Kido as well as mana attacks.
