Trivia

 * Because the live concert took place the day before Hazuki Himari's birthday, she received a decorative birthday cake at the end of the night performance.
 * For this concert, Hazuki taught the other members how to use the DJ sampler. It was used during the performances of Realize and Dounimo Tomaranai.
