Isn't denying Open as an option to bypass Infinity just admitting that Sukuna is done for and that he'll die even if he somehow recovered? Do you truly believe that next chapter will start with Gojo finally killing Sukuna off?
No, why are you so hung up on Open?
Sukuna can transfer/copy the adaptation of Mahoraga to his soul.
Logically, if he could use Open to bypass infinity he would have used it to fight Gojo.
It would be cool if Sukuna can bypass infinity with Open, but like others said, last 10 chapters were for nothing, just a fan service.
I think Sukuna getting Mahoraga's adaptation will be more interesting and it will allow him to use Open on Gojo. The fight will be fair after this;
1) No 3 or 2v1 against Gojo
2) Gojo cant use infinity
3) Sukuna using his own CT and attacks against Gojo's defense other than infinity and maybe some new attacks.
What do you prefer?
