Mr.Fickie talks about Void from the Japanese Manga JuJutsu Kaisen
b"Unlimited Void is one of, if not the most advanced technique in the arsenal of the Limitless. Satoru Gojo inherited the Six Eyes and likely mastered his Domain Expansion after awakening his full potential after the Star Plasma Vessel escort mission. He first displayed his mastery over his domain when he used it to counter Jogo's Coffin of the Iron Mountain. Unlimited Void was the more refined of the two domains and easily supressed Coffin of the Iron Mountain."
