It's an Ohio State tradition. The week of the game against Michigan, the good majority the Ms on-campus, particularly those on outside signs, are crossed out with red tape. One of the local stations this year went the extra mile and replaced all the Ms with an asterisk during any and all game-related coverage. I'm not a huge fan of their football team - my dad being both a Purdue fan and one who hates the Buckeye fandom's "holier-than-thou" attitude might have helped with that - but I might as well do my part as a graduate of/grad student at the university, so there you go.
I did the exact same thing last year, only it was more obvious because I said "Go Bucks" at the end.
That aside, thoughts on all that aired. As I expected, Countdown didn't shake up the Toonami universe like one would think it would. The ending was sort of confusing (so are they gonna try and avoid that killer nebula in the present or not?), but I liked how the point of it was to show how good friends TOM and SARA really are. I totally called that there was gonna be a Black Clover promo, shows Elfie for assuming they wouldn't have one because they didn't show it on Pre-Flight. In regards to the whole "Asta being the only person in the world who can't use magic" thing, my first thought was actually Cross Ange.
