Overview

ニブンノイチ (Nibunnoichi, meaning "one half") is a cover of the J-rock band BACK-ON's own song, originally released as the first opening theme for the anime *Gundam Build Fighters* (ガンダムビルドファイターズ). The track was added to maimai at the launch of ORANGE PLUS on March 19, 2015, and was later removed from the arcade lineup on June 30, 2016, making it one of the earlier removed songs in the series. In Asian English versions of the game, the title was romanized as Nibunnoichi. The song originally sat under the POPS genre in ORANGE PLUS before being recategorized as POPS & ANIME from maimai PiNK onward. On the charting side, the Master difficulty (Level 10) was designed by mai-Star and carries 387 notes with a notably high 18 Break notes, while the Expert chart (Level 7+, constant 7.6) was designed by Jack and offers a 277-note arrangement. Both the Basic and Advanced charts (Levels 3 and 5, respectively) have no credited designer.
