About Seastar
About Seastar...
We are Seastar, an NYC based cosplay and creative idol duo, made up of two members; Sea and Star! We have been officially named SeaStar for our activities since November 2022. We specialize in cosplaying idols and video games, alongside our ability to produce creative stage performances and artistic media.From performing, hosting, cosplaying, crafting, judging, acting and more, we are ready to bring your events to life with our skills, passion and energy!Our inspiration...
Our performances, photoshoots, videos, and other works are a labor of love from everything that inspires us. We take inspirations from 2.5D stage plays, source media, anime, k-pop, j-pop, live concerts, movies, and more.The concept...
No matter the stage, we want to deliver a "stage play" like experience to our fans, including props, character acting, story telling, stage visuals, fan service, lighting, live stage and meet & greet interactions! This passion is the very birth of the concept of "SeaStar".Each moment on stage is a unique moment we all share together. Not everyone will have the chance to see their favorite characters live overseas, so we hope to bring that experience directly to you! ★
