Each episode consists of about 35–40 minutes of Tsubasa's & Hikaru's school life, and is typically concluded by about 5–10 minutes of Maguar fighting. The main point of this series is more about Tsubasa growing up and learning how to cope with life events- such as the loss of her mother and her familiar environment- than the alien-monster fighting which is present throughout each episode. The plot is driven as much by Tsubasa learning from Hikaru and her experiences with her new sister at school as it is by the presence of the Maguar, and there tends to be less cross-interference of mundane and fantastic life than is typical of 'magical girl' type anime.
