ヒビカセ (Hibikase) is a Hatsune Miku Vocaloid track produced by the duo GigaReol, composer and arranger Giga-P, lyricist Reol, originally released on their collaborative 2014 album "No title+". The song made its arcade rhythm-game debut on August 9, 2018, in a rare simultaneous launch across all three of SEGA's contemporary rhythm-game series: maimai (MiLK PLUS), CHUNITHM (STAR PLUS), and オンゲキ (1st). This cross-title release meant players could encounter the same song in three different games on the same day. The title ヒビカセ is a deliberate pun. Its primary reading is 響かせ (hibikase, "let it resound" or "make it echo"), a verb that appears recurrently in the chorus. A secondary parsing yields 日々課せ (hibi kase, "daily charge" or "daily imposition"). Lyrically, the song adopts a meta-perspective: the words are written as if Hatsune Miku herself is addressing the listener, with lines such as "忘れないでね わたしの声を / 画面越しでいい ちゃんと愛して" ("Don't forget my voice / It's fine if it's through the screen, just love me properly"), a direct commentary on the relationship between a virtual singer and her audience. In maimai, ヒビカセ is playable across four standard difficulties. The Master chart (level 13, constant 13.1), designed by サファ太 (Safata), is characterised by dense tap patterns and extended slide sequences, while the Expert chart (level 11) was designed by はっぴー (Happy). The song was removed from Asian versions of maimai beginning with maimai DX BUDDiES and from Chinese versions starting with 舞萌DX 2024, making it unavailable on current cabinets in those regions. It was also delisted from オンゲキ bright MEMORY on March 7, 2024.
