(!!!!THIS MAY CONTAIN LIGHT SPOILERS!!!) This is a very fabulous episode which is originally a special episode of "Kobayashi-san Chi no Maid Dragon S" BTW, this episode doesn't contain any vital events connected to the main plot; you can skip it if you wish. This episode revolves around a hangout between Kobayashi's group and a character that was introduced in "Kobayashi-san Chi no Maid Dragon S" aka Chloe. The art, animation, characters, and sounds are all onthe same level as the main series. Which is perfect!
Personally, I enjoyed it very much as it gives the same vibe as the main series which I obviously liked very much.
If you liked "Kobayashi-san Chi no Maid Dragon S" or are interested in Chloe you should definitely give this a shot. Enjoy 💖
