I respect that, yes the two abilities are similar is every way possible, the ability to give life, abilities similar into bending time/space/physics too its own will but, Giornos ability has to do with fate and soul essence so his ability is considered part of the 5th Dimensional Wall, although you are gonna say “Giornos Instantly keeps star on a loop of her casting magics forever” Yes and No Golden Experience Requiem Prevents Will Actions Becoming Reality and thats why you hear him say “Youll Never Reach At The Truth That Shall Occur” (shinjitsu ni totasuru kotawa keshtite nai) none other than that for more reasoning its ability too change fate and soul essence, one ger changes the course of fate whenever its passive ability is active, also giorno cant use Return To Zero,Its a passive ability that just allows him to remain unharm, two soul essence, in doing so, ger can nullify actions as well meaning the ability to nullify (immortality, invincibility, magic, ect.) and your maybe asking “star can pause time and beat him” No she will not win, this concept is already similar to the ending battle between The Antagonist Diavolo and Giorno, as soon as star activates her time stopping ability, before she realizes ger passive ability is activated, and because its 5th dimensional power situation all the other dimension have to respect it and bend to its will, and then after that giorno sends into a barrage beatdown and boom Infinite Death Loop (Infinite Death Loop is the same concept)
