感情ディシーブ (Kanjō Dishību) is a niconico & Vocaloid-category song by the artist ろーある (Rōaru), added to maimai DX during the FESTiVAL PLUS update on August 18, 2023. The title translates to "Emotional Deceive" or "Feeling Deceive," setting a thematic tone of conflicted emotions and self-deception carried through both its lyrics and in-game presentation. At 175 BPM, the track sits at a brisk mid-to-high tempo characteristic of the Vocaloid scene, with a driving beat that complements its expressive melodic lines. The song is available across all regions, Japan, International, USA, and China, making it one of the more widely accessible additions from that update cycle. Its MASTER chart, designed by Luxizhel, is rated level 13 with a constant of 13.1, placing it among the more demanding single-song charts of the FESTiVAL PLUS era, while the EXPERT chart (level 9+, constant 9.6) was crafted by はっぴー (Happy). The collection titles tied to the song, "「いつか」を夢見たって現状変わんないさ" ("Even if you dream of 'someday,' your reality won't change") for EXPERT S-rank and "不幸は蜜の味" ("Misfortune tastes like honey") for MASTER SSS-rank, reinforce the song's introspective and bittersweet lyrical themes, suggesting a narrative about yearning, disillusionment, and finding a strange comfort in hardship.
