Why. I loved the anime, but it literally cannot use the manga anymore due to events in the season finale. I suppose it would be used for overall plot, since the manga and anime have similar themes. I would enjoy a season 2, but it would have to be parallel to the manga instead of animating it, so it's odd to need to wait for more manga to come out.
