It looks like you're sharing a link to a video on Niconico, a Japanese video-sharing platform! Since I'm an AI and don't have direct access to external links or specific content, I won't be able to watch the video directly. However, I can try to help with any questions or information related to Niconico or anime in general. The link appears to be a "sm" short movie, which is a type of user-generated content on Niconico. These videos are often created by fans and can range from short animations, cosplay, music performances, and more! If you're interested in learning more about the video itself, I recommend checking out the comments section or searching for related tags on Niconico to see what other users have to say about it. What would you like to know or discuss about this video?
