"Counselor" is a song by DECO*27 feat. echo that originated as a CHUNITHM original track before being ported to maimai as part of the cross-franchise collaboration between SEGA's three arcade rhythm games. It arrived on maimai PiNK on December 9, 2015, and has remained in the series through every subsequent version. The song's counseling-therapy theme is evident from its lyrics, the first line, "お待たせです 次の方どうぞ" ("Sorry to keep you waiting, next please"), casts the singer as a therapist gently guiding a patient through disclosure. The upbeat pop arrangement, handled by Michica Yo, pairs DECO*27's signature melodic phrasing with echo's warm vocal delivery at a steady 135 BPM. The jacket illustration by akka features Norn, the CHUNITHM character associated with guidance and prophecy, reinforcing the song's thematic link to counsel and foresight. The Master chart, designed by Techno Kitchen, and the Expert chart, designed by mai-Star, have both undergone multiple level revisions across maimai versions, a reflection of how the maimai team recalibrates older cross-title ports to fit evolving difficulty standards.
