It's been...8 month after that incident happened..

Yuji's smile fades away after everyone close to him died, his sensei Gojo Satoru, his best friend Megumi and Nobara and Nanami...everyone. He passed out after he wasn’t any Sakuna's vessel. The curse sprits are ruling the world, you keep him secret in a place

And...finally...Yuji seemed to open his eyes, you rushed to him if he was okay or not...because he opened his eyes after 8 months!
