Trivia

 * White Day was first observed in Japan on March 14, 1978 by the National Confectionery Industry Association as an "answer day" to Valentine's Day, on the grounds that men should pay back the women who gave them chocolate and other gifts on Valentine's Day. Since then, its observance has spread to several other Asian nations and countries around the world, including China, South Korea, Taiwan, and Vietnam.
 * The costumes that were worn during the performances of "Yosoku Fukanou Driving!", "Waku-Waku-Week!", "Marine Border Parasol", and "SKY JOURNEY" originally appeared in the sixth issue of the LoveLive! Days magazine as the results of a costume design project that had "SKY JOURNEY" serving as the assigned inspiration.
 * For the performance of "BANZAI! digital trippers" during the encore of the Valentine's Day Concert, Hatsune Miku appeared to perform beside Aqours on a screen situated at the stage's bottom floor (behind the performers), a method replicating that found in the song's original music video.
 * The first performance of the aforementioned song, as well as "KA-GA-YA-KI-RA-RI-RA", were both performed by Aqours separately with pre-recorded vocals, although the online livestream during the former included focus on Arisa Komiya and Hatsune Miku either on-stage or on-screen respectively during the sections where they would sing or dance together.
