The clip is linked to Airi Momoi and Shizuku Hinomori, members of the in-game idol group More More Jump from Project Sekai: Colorful Stage. Within the Russian-speaking fan community, their playful ororo vocalization became a small meme, shared as a shorthand for cute, chaotic idol energy. It circulates mainly through soundboards and short-form edits rather than official releases. Creators keep using it because the chant is instantly recognizable to fans, easy to loop, and adds a lighthearted signature to Project Sekai memes, compilations and reaction videos.
About this sound
Airi and Shizuku from More More Jump chant a playful ororo vocal loop. Fans use this cute Project Sekai sound effect for memes, edits and reaction clips.
This nine-second clip captures Airi and Shizuku repeating the nonsense chant ororo in bright, high-pitched voices that overlap and bounce off each other. The rhythm is bouncy and almost musical, with quick repeated syllables, soft giggly tones and a playful idol-like energy. It sounds silly and affectionate rather than polished, like a backstage joke between friends. Listeners usually smile instantly because the loop is catchy, light and a little chaotic, turning an ordinary edit into something warmer, funnier and unmistakably tied to their cheerful personalities.
