Despite being fully aware that the first episode is a bonus without any significant meaning to the original series, it disappointed me and lowered my expectation for the other two episodes.
I'm glad I didn't drop it.
The original 24 episode TV series did not fully appeal to me as it lacked to follow the dramatic scenario set in the first couple of episodes during the rest of the anime. What made me continue watching the anime was not the story, but the character development. The 2nd episode extends that appeal by providing a backstory of the origins of the four dragons.
The weakest point in the original TV series was the abrupt ending it imposed after meeting the yellow dragon. Unlike the other dragons, the yellow dragon seemingly came out of nowhere, with the anime ending without any sort of development in his character.
The 3rd episode of the OVA appeased my disappointment, providing a level of story and character development greater than the entirety of the 24 episode series within the span of only one.
