News after her red-carpet moment, the voice actress reacted to the omnipresence of KPop Demon Hunters-inspired Halloween costumes."Oh my god, it's everywhere, I can't get a break from it. And I'm not complaining, please!"Nonetheless, Rei Ami clarified that she has no qualms about it and the animated movie's impact."Oh, absolutely! And I'm not complaining, please. I want to see more. It is the cutest little thing ever seeing these kids light up. I saw a little TikTok earlier about a mom struggling with Rumi's bubble braid."The breakout star also hinted at the possibility of a K-pop Demon Hunters sequel, saying:"I'm waiting for the call, just like you! You're gonna find out when I do, so we'll chat then."Rei Ami "honored and humbled" by KPop Demon Hunters' successRei Ami also revealed to the outlet the inspiration for her Halloween outfit, showing off the intricate details of her Zoey-inspired costume. It took her three hours to get ready, and overall, 36 hours after she "put my tailor through it.""This outfit is the first outfit Zoey wears in the film. This is when she jumps out of the plane for the song 'How It's Done.' Lots of details. We have the norigae, which is a traditional Korean accessory. We have the sea turtle. We have the embroidery — the hibiscus flower, which is the national flower of Korea."Rei Ami did a quick twirl and also flaunted her sparkly pink nails. When asked about how she comes to grips with the magnitude of KPop Demon Hunters' success, she answered that she can't."This is a cultural phenomenon. The records, the headlines — absolutely unprecedented. So honored, and I think I'm just truly humbled by the power of music and good art, and how we can truly, sounds so cliche but like, change the world. And I think that that's exactly what this film and the soundtracks did."Arden Cho, May Hong and Rei Ami Light the Empire State Building to Kick Off KPOP DEMON HUNTERS Golden Weekend - Source: GettyShe continued:"It brought so much hope and light in such a dim, grim world. I'm so absolutely honored and privileged to be part of it."Before concluding the chat, the reporter asked Rei Ami what her goal for next year is, and the voice actress playfully replied while looking straight at the camera:"World domination!"
