The official website for the upcoming new season of Lostorage WIXOSS has uploaded a new promo and a new visual which you can see above while the promo you can see bellow:

Goboiano describes the story as follows:

“The Lostorage entries focus on Suzuko Homura, a girl who finds herself wagering her memories in a new type of WIXOSS battle. While the winner will have a wish granted, losing all of their memory coins will cause them to lose every memory they once had.”
