Notes & Trivia

 * The paint that the Aqours members used & the small splotches on their faces are based on their color images.
 * This episode also officially confirms that Shiitake is a female dog, as her two puppies are being seen on her front.
 * Shiitake's female gender is also previously confirmed in one of Aqours' stories in Love Live! School idol festival.
 * Shiitake also wore the same pink sweater seen in the second season's opening.
 * This episode marks the debut of Shiitake's puppies and Prelude, Riko's dog.
 * In the Omoi yo Hitotsu ni Nare section of the ending sequence, a scene of the crowd possessing pink-colored glowsticks before it cuts onto Riko playing the piano is a nod to the incident on Aqours First Love Live! ~Step! ZERO to ONE~ day 2, which Rikako broke down while playing the song itself.
 * Before the WONDERFUL STORIES sequence starts, Chika does a similar jumping pose that Honoka did in the Bokura no LIVE Kimi to no LIFE PV.
 * The Love Live Victory Flag made its first appearance since the final episode from Love Live! School idol project.
