ok, first of all i gave this OVA a 10 across the board because there was no flaws with it. This OVA does not take place after or before the main story line. it is simply a gathering of all the characters, even those who didn't make it to the end. The point of this OVA was purely entertainment. in the first half of the OVA your watching a ISDA film with all the main characters in a completely different role then what they had in the anime. Toa's role was closest to her original one being the main female character in love with themain male character, which happens to be howling star in the film. but after that the OVA pics up with every one in a deserted nursing home and trapped inside by a fierce thunder storm which sends a bolt of lighting into an abandoned ISDA research facility and activates a failed experiment with CSS which dont harm the dragons, but instead does one of two things, either amplifies an existing characteristic of there personality, or makes them a 180 degree of there former selfs.

so if you want to see the cast in a pointless but funny and perverted as hell mini episode then watch it, for all you perverted toa fans you'll love the out going, kinky and neko version of toa.
