カラッポ・ノンフィクション (Karappo Nonfiction, "Empty Nonfiction") is an original BMS (Be-Music Source) track produced by Ino(chronoize), featuring the vocals of Masaki Yanase. The song was created for the BOFXV -THE BMS OF FIGHTERS XTREME VIOLENCE- competition in 2019, where it was submitted as part of the team "pop gods." It achieved 8th place in the individual score division and 3rd place in the individual median division, marking it as a standout entry in the competitive BMS scene. Its BMS genre is classified as BOYS FutureCore POP, a style characterized by upbeat electronic pop energy with a forward-looking, polished sheen. The track made its maimai debut in でらっくす Splash (DX Splash) on November 13, 2020, and later crossed over into other SEGA music games, appearing in オンゲキ R.E.D. PLUS (October 2021) and CHUNITHM NEW (January 2022). In maimai, the song features four DX chart difficulties spanning level 3 to 13+. The Master chart, designed by Jack, is notably tap-dense: 631 Tap notes out of 827 total at a 13.7 difficulty constant, making for a stamina-intensive play. The Expert chart was designed by はっぴー (Happy). The jacket art, music video, and visual presentation were handled by TOHRU MiTSUHASHi, complementing the track's energetic, synth-driven soundscape.
