As to how Sakai got involved with the production, it was because of him that this was made possible. Due to the spread of COVID-19, the usual battle stages held at the Wakayama Marina City was cancelled. Hearing the stories of children wanting the battle stage to continue and that he grew up watching hero shows, he decided to get involved. Since he doesn't want to be a producer in name only, he was deeply involved in making sure that the seats and the venue are strictly following measures against COVID-19, and even had close meeting the staff.
In addition, the August 1st date of the event will feature an appearance from GaoBlack himself, Kazuyoshi Sakai as he will held a special stage greeting and photo session. Finally, the August 15th date will have a special event called GaoFes, in which the cast of Gaoranger will reunite for this special performance.
Kikai Sentai Zenkaiger vs. Hyakujuu Sentai Gaoranger Special Battle Stage will run from August 1st to November 3rd at the Wakayama Marina City near Osaka, Japan.
