Action, adventure, fan service. This very underrated OVA does a great job on delivering this combination. A charming fantasy world with awesome wizard and mecha stuff going on that manages to be depicted with clarity in it's short running time. Slap on an absolute babe with a sword and a skimpy outfit and you're set. This is the kind of OVA that people who like cute girls doing cool things will find exceptional, and even if that's not so much your thing the setting is still really fun. It was clear that the people who made this cared very much about the quality of their work.Some of the audio syncing work and some segments of animation are film quality. The main character's design is in my opinion at the highest tier, and the mecha conversion sequences are detailed and fairly original. The talking dog's a little bit wacky but at least he acts as a sort of cape for a few scenes and that's kind of neat. I had a lot of fun with this OVA as someone who enjoys physically attractive and overpowered heroines as well as magic in a science fiction setting.
