Certainly, it's horrible to wait for each episode when an anime is airing. Let alone seasons. That's how I am with JJK, although I had to go read the manga because I can't stand the curiosity anymore.
I had never heard of the manga you're talking about nor the anime, but it looks super interesting. I like the fights, and how the characters are drawn. I'll definitely put it on my list. I might have to read the manga though. Cheers.
