"Ojamajo Doremi Na-i-sho!" is an original video animation (OVA) series of the "Ojamajo Doremi" franchise, released in 2004 with 13 episodes. The story is set during the timeline of the third season, "Motto! Ojamajo Doremi," and follows the witch apprentices' secret stories that happen in their fifth-grade year. Unlike previous seasons, "Na-i-sho!" adopts an episodic format, with each episode focusing on one or more main characters, exploring their personal experiences and emotions, such as Momoko's past, Hana's potty training, and Onpu's path as an idol. The main theme of the series is "secrets," delving into the various hidden thoughts and feelings that children have during their growth. Although released after the fourth season, the timeline of the story is placed during the third season, with Maho-Do still in its sweets shop form. This makes "Na-i-sho!" more of a side story, allowing viewers to delve deeper into the characters' inner worlds rather than primarily focusing on magic and the witch world like previous seasons.
