The day's theme was \"ALL Live Band,\" titled \"-ZESSYOU-\", featuring 14 idols known for their singing ability. The performers included Chihaya Kisaragi, Azusa Miura, Nao Kamiya, and others from various franchises like Cinderella Girls, Million Live, SideM, Shiny Colors, and Gakuen Idolmaster. The live band IWSF BAND, led by keyboardist and bandmaster Shunsuke Takizawa, and the string quartet IWSF STRINGS provided live accompaniment. The setlist included ballads like Azusa's \"Tonari ni...\" and Chihaya's \"Saihyo,\" as well as rock numbers. A notable moment was the performance of \"1/3\" by Ikaruga Luka, with Tsukasa Tsukimura and Retra joining in, which the report highlighted as a powerful display of the live music approach. The event concluded with all 14 idols performing \"Alive Factor\" together with the 8 musicians.","whyItMatters":"The day's staging placed the band on the lower stage and the strings on the upper tier, letting the physical sound pressure of the instruments carry the sense of the idols' presence, a different route to realism than Day 1's dancers.","webCardHtml":"\u003cp\u003e\u003c/p\u003e\u003cul\u003e\n  \u003cli\u003eIWSF BAND members: drummer Kazuhiro Murata, bassist Ryosuke Nikaido, guitarist Shimizu \u0026#34;Carlos\u0026#34; Hiroto, and keyboardist and bandmaster Shunsuke Takizawa.\u003c/li\u003e\n  \u003cli\u003eIWSF STRINGS: Tomo Ito on 1st violin, Risa Yamamoto on 2nd violin, Tomoko Shimaoka on viola, and Yasumi Endo on cello.\u003c/li\u003e\n  \u003cli\u003eThe day opened with Azusa Miura\u0026#39;s \u0026#34;Tonari ni...\u0026#34; backed by strings alone, then Chihaya Kisaragi\u0026#39;s \u0026#34;Saihyo\u0026#34; added keyboard.
