First: This movie schould be watched between episode 39 and 40 of Ojamajo Doremi Sharp (Season 2) because it ends where episode 40 starts. The movie is an episodic side story which takes place during the second season of Ojamajo Doremi. It very much feels like a missing episode also because of it´s length (27 minutes). The story is mainly focused on the character of Pop but we also get a look into Doremi´s character and a nice moment between the two sisters. Because it´s a movie the animation qualitity is higher compared to the animation in the show and it looks very nice. In Conclusion: Tecnically it´snot necessary to watch the movie to enjoy the show but if you are a fan of the characters (like me) then I recommend to watch it.
