MiLK

maimai MiLK, released on December 14, 2017, adopts a white-themed cabinet design and an anime/cafe visual aesthetic, represented by the kanji 白. The headline feature is the new Partner system: players choose one of three voiced companions — Ras, Chiffon, or Salt — before each play. Completing songs earns experience for the chosen partner, and leveling them up unlocks exclusive collection items. Their combined levels form the player's overall level, reviving a progression system absent since GreeN. The in-game currency was overhauled from maiZENNY to Cheese, earned as fragments per song and exchanged for collections, with a global ranking leaderboard tracking total Cheese collected.

The second major addition is the Survival Course mode, which replaces Event Courses with a life-based gauntlet of four tracks — hitting zero HP forces an early end, and the final track features an exclusive song unlockable through course completion. On the gameplay side, Challenge Tracks now allow Master charts to be played without first achieving Rank S on Expert, and all rating restrictions on the Dan course, Utagejou, and Challenge Track categories were removed. The Slide mechanic also received a refinement: when a song changes tempo mid-chart, slides now reference the new tempo for standby timing, fixing inconsistencies from previous versions. The maimaiNET portal was updated with a VS Friends score comparison feature, serial code redemption, and song filtering options.
