Most of this is just new interesting episodes with new characters. But they also revise the ending with one that is better in my opinion. That's pretty much all there is to say about this one lmao. It's a must watch if you liked the previous Saiki K. material. The new characters are cool. It's nice to see some fresh blood after getting to know the other characters so well. Great stuff. It's an extra taste of a show you most likely love if you've watched it to this point. I think it's a Netflix original thingy, I saw this advertisement expressing that's the place it willbe shown. Maybe they just bought the rights to premier it exclusively, not own it if that makes sense.

You should watch this, but of course see the previous seasons first if you haven't. It's an 8/10.
