As shown on a livestream last week. Some parts of the subs could change by the time the OVAs actually roll out (but probably won’t).
Don’t expect too much, this preview is pitifully short in comparison to the one they gave for the prior OVA. But don’t worry—it’s only another two months (and the subs shouldn’t be delayed again).
