Overview
空威張りビヘイビア (Karabiari Behavior) is a maimai original track born from a three-way collaboration between popular niconico utaite (cover singers) un:c and ron, and Vocaloid producer jesus-P (じーざすP). The song serves as Chapter 4, Story 1 of the 言ノ葉Project (Kotonoha Project / "Word Leaf Project"), a multi-chapter series that weaves together Vocaloid originals with utaite vocal performances. The original version features Kagamine Rin and Len, while the version heard in maimai uses the cover recording by un:c and ron. Clocking in at a brisk 186 BPM, the track carries a brash, energetic tone befitting its title, 空威張り (karaibari, "bluffing" or "empty bravado") paired with ビヘイビア ("behavior"). The song entered maimai during the MURASAKi era on December 15, 2016, and has remained available across all regions since its debut. Its charts have undergone several level adjustments over successive version updates, reflecting the evolving difficulty landscape of the series. The Master chart, designed by the duo Revo@LC vs Jack (originally credited under the playful alias "合作だよ", "it's a collab, yo"), features dense streams and slide flourishes that match the song's relentless pace.
