Upon further research, I found that the second OVA was more difficult to track down as it is most commonly referred to as "Doppelganger no Jikan!" for some reason. These two specials in general seem to be fairly overlooked, as they were released alongside the blu-rays of the recap movies. They aren't even technically OVAs, they're more like specials, but it's easier to just call them OVAs.
