Season 4 of Quanzhi Fashi follows the story almost exactly to the manga, with slight changes in the detail. While I highly recommended the manga as the artwork is beautiful and has no corners cut, it is slightly harder to recommend the anime solely based on quality, as the animation can be very poor at times. That being said, the animation of season 4 is slightly better than season 1, and on par with the previous seasons, making it decent at best. Additionally, poor translations really ruined some parts for me, however, I will only take off one point on enjoyment because that is notthe fault of the animation studio. That being said, without the previous knowledge of the story from the manga, I would be very lost at times. Once again, I was never into manga, however this was the one exception, and I highly highly recommend the manga for Quanzhi Fashi, while the anime is slightly worse in my opinion. Therefore, I rate Quanzhi Fashi season 4 as a 7, as it is just good, definitely not great, but if you liked the past 3 seasons, you will like this season.
