Overview
Customized Justice is an instrumental speedcore track composed by Kobaryo for maimai でらっくす CiRCLE, the August 2025 update of the maimai DX series. The song marks Kobaryo's return to the series after Raven Emperor from the PRiSM era, but trades that earlier track's more measured composition for an unrestrained, high-BPM speedcore assault, the style the composer is best known for in the BMS and doujin scenes.
Customized Justice debuted as the LEGEND-class boss reward in CiRCLE's Friend Matching (オトモダチ対戦) system. Players who climbed to SSS1 class faced a dedicated boss friend; defeating it granted access to the song upon reaching LEGEND rank. The track also functions as a conduction song (伝導楽曲): players who have unlocked it can pass it to others by playing together on the same cabinet in multiplayer mode. Over subsequent months, additional unlock routes were introduced through special boss friends, and the song became permanently available to all players with the launch of CiRCLE PLUS in March 2026.
Regionally, the song was handled differently outside Japan. In the International and Asian versions, 7 Wonders took its place as the SSS1 boss reward, while Customized Justice was made available as a standard default-unlocked track from March 5, 2026, making it the first song since BATTLE NO.1 to be exclusive to Friend Matching only in the Japanese version. The music video was produced by Ehre_origine, whose visuals complement the track's relentless speedcore energy.
