It looks like you're excited about a video featuring Batman and the Yakuza League in an epic battle set in feudal Japan. "Batman Ninja" is a unique take on the Dark Knight's character, where he navigates through samurai-era Japan as a stealthy ninja.

The video seems to be promoting a special event or animation related to Batman Day (which might be July 23rd, but I'm not entirely sure). If you're interested in watching the video, simply clicking on the link should take you to the Nostr building where the video is hosted.
