I'm not really sure what to say at this point. There's a certain level of confidence these folks are putting off when they come in. "An unhealed heart, his domain is sealed" and from him being wounded too, but it's all ended the exact same way like a chapter later. These newcomers are gonna get absolutely gobstomped by Sukuna next chapter.
I guess we just gotta wait until Yuji has some aneurysm level angy and unlocks some special Sukuna slapping power before this ends. I'm betting.. about 15-20 more chapters before we see any semblance of an ending.
