Wooooooo. A bit bummed that we're not getting the other half of AssClass right away, but it's good to know that we will in the future.
Also it's not hard to figure out why Toonami aired the first two seasons of Food Wars back-to-back but is giving AssClass a break in-between. Sentai had just announced the license for season 3 right around when the block started airing it, so it'd be good promotion for their release of the next part. I don't remember if they'd released season 3 by the time that season 2's run finished, but I think it was pretty close, and they may not have had the broadcast rights worked out at the time. In contrast, AssClass is a pretty deep catalog title for FUNi at this point, so there's not really anything that'd be promoted by continuing on with it immediately.
