Overview
Wah Wah World (ワーワーワールド) is a collaborative track between Giga and Mitchie M, two of the most prominent producers in the Vocaloid scene. The song was created as a theme for Project Sekai: Colorful Stage! feat. Hatsune Miku, a mobile rhythm game that blends original characters with Vocaloid icons. The track features Hatsune Miku alongside Minori Hanasato (voiced by Yui Ogura) and Kohane Azusawa (voiced by Akina), two characters from Project Sekai's cast. Mitchie M wrote the lyrics, which encourage listeners to embrace their individuality and find their own "world," while Giga handled the arrangement, delivering the high-energy electro-pop sound both producers are known for at 160 BPM.
The song first appeared in Sega's ONGEKI bright arcade rhythm game in January 2022 before arriving in maimai DX FESTiVAL on October 7, 2022. The maimai version uses a shortened 1:45 edit of the full track. Its MASTER chart, designed by 翠楼屋 (Suirouya) at level 13.0, is notable for its dense Slide-note patterns (74 slides) that match the song's bouncy, exuberant energy, while the EXPERT chart by アマリリス (amaryllis) sits at a 9+ difficulty with a constant of 9.6.
