This is just a series recap episode that tries to be a bit different by telling it from the perspective of Verudora and Ifrit inside of Rimuru. It's really not anything special, because the comedy isn't really that funny in it and there's no investment in watching these two bond, because they were only a part of the story for like 10 minutes each. You only need to watch this if you've dropped Tensura for a while and are coming back to it and need a refresher on what happened. As far as entertainment value beyond that, it's nil. Not unlessyou're into tertiary characters playing shogi and talking about loneliness.
