Basically, actors etc can’t work without an agency, legally & logistically. Her agency dropped her, so she can’t work on anything & Toei can’t have her continue on the show or use anything of her after her contract ended.
(Toei is def not perfect, but the agency is the big problem out of the two)

I can have a little Nagumo kick. As a treat.
