The second season of Kagejitsu is quite a bit better than the first. It's still just chibi shorts but they're way less chliché and actually add a bit to the main anime now. The events in the shorts are about a detail or theme from the episode of the main anime with the same number. This means that the best time to watch a short is after finishing an episode but you can also just watch them later if you forget. The humor is all in all quite enjoyable. The characters are the seven shadows and all of them get some attention. The animation is aboutas good as you're going to get for chibi characters and the voice acting/music is fine too.

Overall these shorts are a pretty nice addition and fun to watch if you're a fan of the anime/characters but probably not worth your time if you dislike the main anime or dislike chibi animation.
