All songs

Overview

ボッカデラベリタ (Bocca della Verità) is a VOCALOID song by producer Hiiragi Kirai (柊キライ), written, composed, and arranged entirely by the artist, with vocals provided by the voicebank flower. The title draws from La Bocca della Verità (Mouth of Truth), the ancient Roman marble sculpture said to bite the hands of liars, a motif that echoes through the lyrics, where speaking becomes an act of revealing or concealing truth ("喉を過ぎればそれは真実", "once it passes through the throat, it is the truth"). First released on Hiiragi Kirai's 2020 album ヘイトフル (Hateful), the track crossed into SEGA's rhythm game lineup starting with オンゲキ R.E.D. PLUS in April 2021, followed by a CHUNITHM NEW appearance in February 2022. It arrived in maimai でらっくす FESTiVAL on March 10, 2023, where it sits in the niconico & VOCALOID category. The song's brisk 170 BPM and sharp, electronic-driven arrangement showcase Hiiragi Kirai's signature production, abrasive yet melodic, with flower's piercing vocal timbre cutting through the mix. Within maimai, the EXPERT chart (designed by 翠楼屋 / Suirouya) stands out for containing zero TOUCH notes, a rarity among DX-format charts that makes it play more like a traditional STANDARD-style layout despite being on the DX side. The Master chart, designed by Redarrow, leans harder into the slide-and-break patterns typical of higher-level DX charts, reaching a 13.2 difficulty constant with 796 total notes.

Trivia

The song title ボッカデラベリタ is a Japanese phonetic rendering of the Italian phrase Bocca della Verità (Mouth of Truth), referencing the ancient Roman marble mask housed in the church of Santa Maria in Cosmedin.
The lyrics center on themes of truth and deception, with the recurring line "喉を過ぎればそれは真実" (once it passes through the throat, it becomes truth), a direct nod to the Mouth of Truth legend, where a hand placed inside the mask would be bitten off if the speaker lied.
The EXPERT chart has zero TOUCH notes across its 539-note layout, a rare characteristic for a DX-format chart in maimai. As a result, the results screen displays no TOUCH judgment breakdown, treating the chart like a STANDARD-mode play for that category.
Hiiragi Kirai was responsible for composition, arrangement, and lyrics, a solo production credit that reflects the artist's independent doujin/VOCALOID scene background.
The track originally appeared on the 2020 album ヘイトフル (Hateful), which collects several of Hiiragi Kirai's VOCALOID works featuring flower.
Before arriving in maimai, ボッカデラベリタ was already playable in two other SEGA rhythm games: オンゲキ R.E.D. PLUS (April 2021) and CHUNITHM NEW (February 2022), each with distinct chart designers and note layouts.
In オンゲキ, the song is associated with the character Kashiwagi Mia (柏木美亜) at level 26 as the opponent character.
Different chart designers handled the song across the three SEGA games: 翠楼屋 (Suirouya) and Redarrow for maimai, Techno Kitchen and じゃこレモン for CHUNITHM, and ものくろっく (monoclock) and あまりりす (amaryllis) for オンゲキ.
