Nice thread
@Kuro Ashi :cheers:
Anyway, there's that one theory on Reddit and the video on YouTube (forgot where it is) that talks about how Zoro cutting pretty much a nonexistence being and how Zoro will achieve "dimension slash" in the future.
Mahito from Jujutsu Kaisen stated that emotions come from the soul. People overthink the things that they can't see.
If Shiryu can manage to alter his soul so that he wouldn't get hit physically then that would be cool. Zoro vs Shiryu will probably be similar to Yuji vs Mahito.
What if Zoro going one step even further? The boundaries of life and death can allows Zoro to cut anything in existence and nonexistence. And this is where dimension slash coming in.
In Black Clover, Yami uses dimension slash to cuts the things that he can't physically touch. Zoro having dimension slash would be useful against Shiryu since Zoro can't physically hit him.
