So maybe it's going in the direction of both editors having a say? It would feel weird to just now drop the "evil editor" altogether.
I feel the same way. If the old editor tries to sabotage the work of the new editor, Nikaidou would have an excuse to go against him without making trouble for the publishing company. The new editor would shield Tadokoro, so no problems on that side either. I think there's a chance it goes this way.
