Bleach: Gathering! Rukia's Rescue! Shining! The Ultimate Shinigami Showdown! Special Showing of the Shinigami Teams!

So, I found the episode somehow from Reddit of all places; it's actually 48 minutes long that consist of some commentary by the characters of the couple of fights in the first 62 episodes; then the rest is basically episode 63 and quick preview of episode 64. Don't get why did they do it that way back in the day and more importantly why it's very vague as to what it is, very hidden and very hard to find (It took me 3 days). TL;DR You don't need to watch it It wasn't predictable The art style is fitting for the story the characters were well-rounded the characters react tosituations and events in a realistic way others will enjoy/dislike this series
