What’s it called
Also, for reference, the first volume of the new arc has been summarised in detail already. https://dreadfuldecoding.blogspot.com/2019/02/sao-v21-summary.html
Does moon cradle count as alicization? It happens between alicization ending tho.
I have no idea
Moon cradle or Unital ring...?
Probably unital ring
Moon Cradle is an Alicization side story that isn't relevant to the main story. It basically just a story that takes place during a time skip in the Alicization arc.
What do you think?
