Chorogons no Namahousou 3
This was a live broadcast for the TV anime Kobayashi-san chi no Maidragon. The seiyuu hosts were the four main seiyuu of the dragons. The guest was Katou Emiri.
It seems Maria was slightly sick or something, as she couldn't speak much. She used a sketchbook and wrote down what she wanted to say.
