Overview
劣等上等 (BRING IT ON) is a VOCALOID-driven electronic rock track composed by Giga with lyrics by Reol, originally featuring Kagamine Rin and Kagamine Len. The version that appears in maimai でらっくす Splash is a human cover performed by Vivid BAD SQUAD, a unit from the mobile rhythm game プロジェクトセカイ カラフルステージ！ feat. 初音ミク (Project Sekai: Colorful Stage! feat. Hatsune Miku). In this rendition, the synthesized voices of Rin and Len are layered with live vocals by Kohane Azusawa (voiced by Akina) and An Shiraishi (voiced by Tomomi Jiena Sumi), giving the track a distinct energy that blends VOCALOID production with human performance. The song's title plays on the contrast between 劣等 (inferiority) and 上等 (excellence), projecting a defiant, self-assured attitude that matches the driving 160 BPM beat and rapid-fire lyrical delivery. Released in maimai DX Splash on January 21, 2021, the track sits in the niconico & VOCALOID genre category and carries a Master chart with a difficulty constant of 13.2, designed by サファ太 (Safata). Its regional rollout was notably staggered, the Asian version did not receive the song until February 2023 as part of DX FESTiVAL, marking the first time a song's release was delayed in that manner for the Asian maimai DX arcade market.

Trivia
- The song title 劣等上等 is a deliberate wordplay: 劣等 means 'inferiority' and 上等 means 'superiority' or 'first-rate.' The compound reads as a defiant declaration, roughly 'I'm inferior and that's fine, bring it on', which is exactly what the official English title, BRING IT ON, captures.
- Lyrics were penned by Reol, a Japanese singer-songwriter who built her early career in the VOCALOID doujin scene before achieving mainstream success. She and Giga have collaborated on multiple celebrated VOCALOID tracks.
