Anime-Inspired STEM Streetwear Brand

In a world full of basic designs and faceless brands, Neon Theorem was created to feel different.

We’re an independent streetwear brand inspired by anime visuals, urban fashion, science, math, design, and self-expression. Our goal is to create apparel for people who think differently, create boldly, and wear what represents their mindset.

I created this brand to bring together my interests in anime, design, science, math, creativity, and streetwear — turning those ideas into original clothing that feels smart, aesthetic, and unique.

Thanks for being here.
