Where can i find the full Japanese video? Also if you know the name of this video,please let me know.

I know this is not Anime related. But it is Japanese. If you know where i can get the full video,please let me know. Send me a link if you can as well. I gotta find out what happens next in the video. It cannot leave off as a cliffhanger when it's getting to the good part of the video. Please don't judge me for watch this.
