I loved watching this one! So you get the plot of the story through about half of this video, and I was sad for the main character and happy at the same time, but mostly sad.
Animation was fantastic, loved how everything was detailed and was very smooth and bright, even in the dark portions of the anime. Sound was equally fantastic, was a great song throughout the video and was fun to listen to.
You don't really get the character at the beginning, but then as the anime progresses you start to see the situation and feel for this character.
Overall this is a great one to watch and I will probably watch this one again.
