You didn't list what that was for, but reverse image search lets me know it's for the Black Clover Jump Festa special. I only looked up some of the staff members, but it does appear that most of the people were involved with Fafner Exodus in at least some capacity. The director is Takashi Noto, chief director of Exodus; the character designer is Noboru Jitsuhara, who was an animation director on Exodus; the art director is Yoshio Tanioka, who contributed to Exodus' backgrounds as part of Biho; the CG director is Eiji Inomoto, from Orange; the color designer is Ayumi Ikeda, who participated in a couple Exodus episodes; and the director of photography is Yuuichi Tsuzuki, who was working in the Xebec photography department for Exodus.
