Jujutsu Kaisen for sure. I'm sure lots of people have either heard of or read the Shibuya arc, so I won't repeat it anymore.
Tower of God is gonna be nuts for the new season. Season 1 was really good, but it is also similar to JJK Shibuya where the level up in content/writing/development is going to blow people away.
I'm pretty stoked for the vending machine isekai, it looks rad. Overall next season looks pretty great with a decent amount of new stuff (some of which are based on manga I'm reading and enjoying) and some continuing seasons.
I'm thinking Vending Machine will be either really great or really awful. It all depends on the execution. I can see it being really gimmicky, and the gimmick(s) wearing thin quickly. On the other hand, if the writer(s) manage to pull it off in some ingenious fashion, it'll be something to see.
The 100 Girlfriends Who Really, Really, Really, Really, Really Love You
I know it sounds dumb, and it is. It’s just dumb in the best possible way. This manga is just absolutely insane.
It’ll be interesting to see how people react to this series. A ton of people will likely write it off immediately based on the premise alone, but man this series is just so much fun. I hope the anime adapts it well.
Spy Kyoushitsu 2nd cour. First one was fun, especially in the "manor" arc that concluded it. Other than that, I have high hopes for Zom 100, since it gives off Zombieland Saga vibes and that series had no shortage of great scenes in either season.
