オーバーライド (Override), maimai DX PRiSM Song

All songs

Overview

オーバーライド (Override) is a high-energy VOCALOID-style track by Japanese composer 吉田夜世 (Yasei Yoshida), featuring the SynthV/UTAU voicebank 重音テト (Kasane Teto) on vocals. Originally released as a standalone single/album in 2023, the song entered maimai でらっくす PRiSM (maimai DX PRiSM) on December 6, 2024 as part of the niconico & VOCALOID category. At a relentless 204 BPM, the track pairs a driving electronic-rock instrumental with Teto's signature synthetic vocal, a combination that earned it placements across all three SEGA rhythm game siblings: CHUNITHM VERSE and オンゲキ Re:Fresh in addition to maimai. The title "オーバーライド" (Override) carries a dual meaning that savvy programmers will catch: it is both a general term for overwriting a system and a specific Java annotation (@Override) used in object-oriented programming. This programming motif surfaces in the CHUNITHM ULTIMA chart designer credit, literally listed as NullPointerException, and is echoed in the music video's visual language. On the maimai side, the MASTER chart (level 13.4, designed by Luxizhel) contains a cleverly literal SLIDE pattern: at the lyric "半端な生命の関数を" (the function of half-baked life), the slide path traces the shape of the mathematical function notation f( ), turning the chart itself into a visual pun.

Trivia

The MASTER chart (designed by Luxizhel) features an 'f'-shaped SLIDE that visually spells out mathematical function notation f( ), directly corresponding to the lyric '半端な生命の関数を' (the function of half-baked life).
The CHUNITHM VERSE ULTIMA chart lists its designer as '*NullPointerException*', a deliberate reference to Java's NullPointerException runtime error, playing on the programming theme of the song title (the @Override annotation in Java).
The music video was created by the illustrator/animator シシア (Shishia), who also contributed visuals for other SEGA rhythm game tracks.
The song appears across all three major SEGA arcade rhythm games: maimai DX PRiSM, CHUNITHM VERSE, and オンゲキ Re:Fresh, with staggered regional release dates.
In Asian regions, オーバーライド was added to maimai on May 9, 2025, and in the Chinese version (舞萌DX 2025) on March 25, 2026, while the Japanese version received it at PRiSM's launch on December 6, 2024.
In-game achievement titles reference lyrics and themes from the song: '誰だこんな親クラス作ったのは' (Who made such a parent class), '哀れ、あはれ' (Pitiful, ah…), 'もうこないからねー' (I won't come anymore), and '少々ここらでオーバーライド' (Let's override around here).
The でらっくすコレクション title '誰だこんな親クラス作ったのは' (Who made such a parent class) is another programming in-joke, 'parent class' being the object-oriented programming concept that child classes override.
Kasane Teto, the vocalist, originated as an April Fools' joke in 2008 but became one of the most popular UTAU voicebanks; this song uses her Synthesizer V (SynthV) voicebank, Teto SV.
The EXPERT chart (level 11) was designed by サファ太 (Safata), who has contributed numerous charts across the SEGA rhythm game series.
