Although Yuuko has the ability to predict the future, she often visits a fortuneteller whom she lovingly refers to as “Oba-chan”. Once, when Watanuki accompanied her, Yuuko explained that one cannot predict their own future of else there will be chaos. Nevertheless, Oba-chan is one of Yuuko’s oldest friends and is the only one in the entire series to call Yuuko “Yuuko-chan”.
Isn’t IZUMI (和泉) absolutely gorgeous? I know I’m now a huge fan of hers since she cosplayed one of my favorite characters so perfectly! If you’d like to see more of her work, please support her though Archive, Cloud, Cure, and World Cosplay! Thanks to Jai for sending this in!
