I suppose this anime was planned to have more than two episodes, but it must have been cancelled and they released the two episodes already produced as an OVA. I even thought it would be a bad anime since the synopsis doesn't catch the attention and is a bit "confusing", that is until I saw the anime. If this anime was a series longer than 12 episodes, it would probably still be episodic, with two girls who travel back in time, meet someone and help that person with their heartfelt ways. Yes, you remember Natsume Yuujinchou because of that, but it's quite different. At first I thought Chronwas too silly, but I got used to that. Escha liked her better in her own way.
They are two characters who have some purpose, but we will never know what it is because it will never continue. Many mysteries remain unanswered. These two episodes are basically an introduction.

The animation is pretty consistent. The character design isn't great, it's the usual generic (unfortunately).

As much as it caused me a little embarrassment to watch the first episode because of the characters singing, the second one was much better.
Although I was average, I enjoyed watching it, and didn't think it was a waste of time. It's an anime that would have more potential if it was about 12 episodes long.
