The 10th anniversary logo features Kyoryu Red's helmet, and the #10 seen in the show's collectible gimmick, the Zyudenchi. The first of its anniversary celebrations is that the series will be streaming on YouTube for free starting this July 30th at 10am JST. Two episodes will be released every Sunday.
This is just the start of more future Brave projects as this anniversary project aims to deliver surprises that have never been achieved in Super Sentai!
