When Valkyrie first meets Kurt and Riela and they introduce themselves by their numbers, Kurt being 7 and Riela being 13, Valkyrie decides to call herself 17. This is a direct reference to Valkyrie's voice actress Kikuko Inoue, who often jokes that she is 17 years old when asked about her age.

In the cast listing, the actor credits for the characters Sakura Shinguji and Ichiro Ogami are flipped.

Followed by Project X Zone 2 (2015)
