Where art imitates life and life imitates art every single day of the year! You didn't think Yuno's story was over, did you? Of course it isn't, but if you've seen the first series of Hidamari Sketch, you should know not to expect the "A happens after B after C" pattern of the rest of the world. In fact, instead of just taking place after Yuno's first year at Yamabuki High, X365 continues the saga on both sides, around and in-between, filling in the details in an ever-expanding collage that's both avant-garde and slice of life! And if the format's not completely unexpected, we guarantee that some of the things that you never knew about before WILL be! Yuno, Miyako, Hiro, Sae and all the rest of the denizens of the most fascinating piece of surreal estate in Japan are back as the medium becomes the message in Hidamari Sketch x365!
