Overview
アカリがやってきたぞっ (Akari ga Yatte Kita zo) is a VOCALOID original song composed, arranged, written, and animated by GYARI, featuring vocal synthesis character Kizuna Akari (紲星あかり). It debuted in maimai でらっくす (maimai DX) on July 26, 2019 as part of the limited-time GYARI Area event, and later became a permanent addition to the lineup. The song also crossed over into Sega's other rhythm game titles, CHUNITHM CRYSTAL and オンゲキ R.E.D. PLUS.
What distinguishes the track from a conventional VOCALOID pop song is its near-exclusive use of Japanese onomatopoeia (擬音語) and short action noises in place of traditional lyrics. GYARI wrote the entire vocal line from sound effects, "ガタンゴトン" (a train's clatter), "シュッ" (whoosh), "モグモグ" (munching), "ペロペロ" (licking), and many more, delivered through Kizuna Akari's VOCALOID4 voicebank and her supplementary exVOICE audio material. The result is a playful, cartoonish soundscape that foregrounds the character's expressive energy over narrative meaning.
The maimai Master chart (level 12+, constant 12.7, designed by Moon Strix) is most famous for its "ガタンゴトン" passage, where a rapid volley of alternating Slide notes mirrors Akari's swaying motion in the original animated PV. The chart makes extensive use of Touch and Slide notes, leaning into the DX format's touch-based mechanics. The Expert chart was designed by 華火職人 (Kanon Oguni). Notably, starting with maimai でらっくす UNiVERSE PLUS, the song's in-game background video was removed, leaving only the jacket illustration as the visual backdrop, a change that has remained in subsequent versions.

Trivia
- The song uses VOCALOID4 紲星あかり (Kizuna Akari) plus her exVOICE add-on material, but unlike GYARI's earlier maimai contribution 'Seyana. ～何でも言うことを聞いてくれるアカネチャン～', it does not incorporate VOICEROID speech synthesis, GYARI himself noted this distinction.
- The title アカリがやってきたぞっ translates to 'Akari Has Come!', a fittingly direct introduction for the character.
- The Master chart's signature 'ガタンゴトン' section pairs alternating Slide notes with Kizuna Akari's swaying body motion in the original PV, creating one of the most visually and physically synchronized moments in the chart.
- The song was initially unlockable by accumulating 10 m of total distance in the GYARI Area (GYARIちほー) event from July 26 to October 3, 2019. It became available by default the following day.
- The in-game background video was removed starting in maimai でらっくす UNiVERSE PLUS; Sega did not publicly explain the removal, and later versions display only the jacket artwork.
- A collection title (称号) awarded for rank S on the song reads 'ガタンゴトン ガタンゴトン ガタンゴトン ガタンゴトントン', the same onomatopoeic phrase that anchors the song's chorus-like refrain.
- The song appears in three Sega rhythm game series, maimai, CHUNITHM, and オンゲキ, each with slightly different edit lengths. The maimai version runs 2:27 while the CHUNITHM and オンゲキ versions are 2:32.
- GYARI created the animated music video himself, combining the character art with motion that directly inspired the Master chart's slide patterns.
- The Expert and Master charts were designed by two different creators: 華火職人 (Kanon Oguni) for Expert and Moon Strix for Master.
