So basically this OVA for me is mainly for fan service purposes only.
Will not satisfy your craving for the anime.
Though I must say that it sort of opens your heart more with the green dragon and makes you a bit more curious about his back story as well as the yellow's since we all know they had tiny bit of back story compared to the first two dragons.
What I like about this ova is the fact that clearly the whole gag is getting along well, and I just can'twait to see more brotherly interactions of the 4 dragons.
