Premieres in Japan June 27th. The new PV is here. Check out the ANN article for additional information. Synopsis of the source manga from AniList:
Miss Kobayashi is your average office worker who lives a boring life, alone in her small apartment–until she saves the life of a female dragon in distress. The dragon, named Tohru, has the ability to magically transform into an adorable human girl (albeit with horns and a long tail!), who will do anything to pay off her debt of gratitude, whether Miss Kobayashi likes it or not. With a very persistent and amorous dragon as a roommate, nothing comes easy, and Miss Kobayashi’s normal life is about to go off the deep end!
Wait… What do they recognize it as then…?
Completely sincere. Beats me how they miss it, but boy oh boy do they ever, and it… goes downhill real quick from there.
It’s not a factual documentary?
