Allow me to be the first real review. My main issue with this season is the main conflict is so...contrived. I won't spoil anything but just know this entire season could have been avoided if certain characters had just had a conversation instead of the mental stand off they opt for.
And for the class competitions, it's like the first one but worse. Stuff happens for a few episodes, you aren't given any details and are lead to believe class D is going to come in last, then wam bam of course they don't because of these 10 things that happened off screen. Ayonokoji is basically God with his ability to see the future. All that being said, if you're trying to fill the time it's not bad for that. Just don't expect good story or character development.
