There’s no commonly triggering content. However, given Enstars’ history of Middle Eastern-inspired outfits and use of its culture, your mileage may vary with how it’s represented in this story. It only comes up in the end for Akatsuki and Ra*bits’ performance and tied into the visual and conceptual themes of the story. I’m in no position to judge whether it’s culturally appropriative or not as I’m not a member of Arabic cultures/groups.
