The Next episode after this is called Blue Roses, it would seem they are going to switch things around a bit in timeline. which is no problem as we never actually got an idication that the situation happen before or after each other just around the same time.
Does anyone know why Overlord couldn't receive a season of 24 or 13+ episodes? Seems like it could benefit from it and not feel rushed for those who have complained about it so far. Black Clover seems to be one that has many episodes yet isn't as well received as other animes.
