IOSYS

IOSYS is a long-running Japanese doujin music circle best known for their high-energy remixes and playful arrangements of themes from the *Touhou Project* video game series. Since the early 2000s, they’ve carved out a niche blending J-pop, electronic, and rock styles with meme-worthy humor, becoming a staple in anime/gaming convention culture. Their prolific output includes series like the *TOHO BOOTLEGS* albums and *ROCKIN'ON TOUHOU* compilations, which reimagine *Touhou* tracks with everything from dance beats to cheeky vocal shenanigans.

Though largely anonymous as a collective, IOSYS’s work thrives on collaborations with vocalists and illustrators, embracing the DIY spirit of Japan’s doujin scene. Their tracks, like the viral hit “Marisa Stole the Precious Thing,” often spill into internet meme culture, while live performances and Comiket releases keep fans hooked. If you’ve ever stumbled into an anime convention dance party or a *Touhou* fan forum, chances are you’ve vibed to IOSYS’s quirky, rainbow-splashed sound.
