It takes content from episodes 1 to 13 as said in the synopsis so it's not full of information. I wish this recap were from the 24 episodes but maybe they don't do it cause it'd be too long, idk.
Although it's skippable I'm writing this because I found interesting how a recap from 2009 tells you that this story won't have a happy ending (it's Dec 2021 and the manga is still on).
I'd suggest a watch to fans just for those short phrases Tanaka says about the ending.
