A Certain Band's Sports Festival☆/Event Story

Trivia

 * As this event is a collaboration between BanG Dream! Girls Band Party and Toaru Kagaku no Railgun T, there are numerous references to Toaru Kagaku no Railgun in the event story and card stories. They include:
 * The event story takes place during a joint sports festival between different high schools, identically to the Daihasei Festival Arc.
 * The joint sports festival committee Poppin'Party joins is similar to the Judgment.
 * In Arisa's Card Story, Rimi and Tae mention running into a person who "looked exactly like Arisa from behind, had twin tails, referred to someone from her school as her onee-sama, and had a quirky way of ending her sentences." Arisa then proceeds to imagine a scene where she is the girl and Kasumi is her "onee-sama".
 * In Rimi's Card Story, Saaya and Rimi are going through the lost items in the Sports Festival's committee room. They end up finding a frog mask, a hair accessory made out of flowers, futuristic goggles, and a remote.
