Astarotte's Toy EX

Astarotte's Toy EX is a short series of original video animations released in 2011, serving as a companion to the television anime adaptation of the light novel series by Asu Mikage. Produced by studio diomedéa, these OVAs were designed to expand upon the fantasy world of Yggdrasil, where the princess Astarotte Ygvar attempts to recruit a human male into her harem. The production team aimed to maintain the lighthearted, comedic tone of the source material while utilizing the OVA format to explore character interactions that fell outside the primary narrative arc of the television broadcast.

The character designs for the project were adapted for animation by Keiya Nakano, who sought to capture the distinct aesthetic established in the original illustrations. The series is part of a broader trend of mid-2010s fantasy-comedy anime that combined supernatural elements with domestic social dynamics. Upon its release, the project was received as a niche entry for fans of the franchise, noted primarily for its technical continuity with the studio's broader body of work and its commitment to the specific character archetypes established in the initial light novel volumes.
