LaLaLa Goodbye Personality! (LaLaLaグッバイ個性！, Lalala Goodbye Kosei!)? is the trailer theme for the fourth labyrinth. In the Persona Q2: New Cinema Labyrinth Original Soundtrack, its artist is simply labeled as (ひかり＆花＆クマの着ぐるみ＆木こり＆小人たち, Hikari to Hana to Kuma no Nuigurumi to Kikori to Kobito Tachi)?, which consists of Misato Fukuen and several uncredited voice actors.
- The following are the official lyrics from Persona Q2: New Cinema Labyrinth Original Soundtrack and the in-game trailer.
"watashi, watashi wa dare?"
Who.. Who.. Who am I?
- Each of the Hikari copies in the trailer sing lyrics that are related to the "morals" of previous labyrinths and are presented in the reverse order of when they are encountered.
- The copies of Hikari can be seen telling the real person to give up her personality. However, they are friendly when encountered by Hikari herself and the party, foreshadowing that she forced herself to believe that if she did not stand out she would not get driven to such extreme depression and self-loathing.
