Kayanomi #4 is up and run on Youtube on animate Times channel. This is pretty much the continuation of Kayanomi #3. The title is 「料理と日本酒 その2」 translated more or less as “Cuisine and Sake Part 2”. Still takes place in Kudaka restaurant located on Roppongi, Tokyo. Two more foods and two more sake(s) are introduced in this episode.
I am going to say that at this point the show becoming less attractive. I feel that Kayanon failed to things more interesting. She is indeed beautiful, gentle, and charming but perhaps not quite good as presenter.
