I'm copy pasting this review from my review of the fourth season because in all honesty, nothing has changed. If you enjoyed any of Teekyuu at this point, go ahead and watch this. It's pretty consistent throughout the seasons. If you didn't like Teekyuu, then I suggest that you don't watch this. It's probably not anything you want to see. It's pretty simple. Even though that's all pretty self-explanatory, let me put some stuff out there for people who marginally enjoyed the first few seasons and aren't sure whether to continue. The story, art, sound, and characters are all pretty true to whatthey have been in earlier seasons. There's nothing more to say about that. Not much has changed, except that the art seems to continuously get better, including the animation. The sound is a little clearer, and now there are sometimes arc episodes. There are some running gags instead of just regular randomness. I suggest you watch most of it one sitting if you want to catch some of the reoccurring jokes. That's pretty much all there is to it. :)

Have a great day everyone!
