Return of the Abyss is a 3-Parted OVA for the St. Sky Stories, the timeline takes place in between Season 4 and Season 5 of the series. The city has been free of any problems for about 2 weeks straight, however one night when Haseo was wondering around the Lost Grounds, he came across a sharp object and noticed that it was being magnetically pulled to somewhere. He followed the trail and found a huge orb of some sort, he poked it with the sharp object and accidentally activated the orb which unleashes all of St. Sky's past antagonists. St. Sky will now have to deal with the past antagonists once again, but this time all of them at once!

The second and third part of the OVA was originally unplanned, therefore the storyline does not completely connect to the first part of the OVA. The second part of the OVA tells the story of few more antagonists that weren't defeated in the first part and they plan to get their revenge for their masters that have been defeated in the first part. New characters and locations are featured in the second part due to the fact that most of the storyline in the first part is finished and that the second part cannot connect to the first part properly. The third part is the continuation of the second part of the OVA and it has not been aired yet.

Because the second part is not completely connected to the first part, the storyline will still be understandable if the first part is not watched. However the second part is required to be watched in order to understand the third part because the storyline continues from the second part.
