This is a rather late reply but:
It has a very long cast time, but will give super armor eventually, the domain has two effects:

The first one, which will activate as long as the music goes through and lasts beyond the domain breaking, will give yuji a set of extra moves

The second effect will constantly damage your opponent, similarly to malevolent shrine. The secondary effect relies on you fully casting the domain, and the enemy being inside the domain (it has a limited range). If you are damaged enough, the domain will "break" and disable the secondary effect.

You cannot move from within the domain to the outside world, or the outside world to the domain, once the domain is active.
