This is a short commemorating the 15th anniversary of Battle Spirits Shounen Toppa Bashin (and the card game overall) and the 10th anniversary of Battle Spirits Saikyo Ginga Ultimate Zero. It's 5 minutes long, don't expect much from it, but it's fun as a chance to see the old characters again. Pretty much everyone relevant at least cameos in here, but most don't have a speaking part. But, yeah, STB is my all-time favorite anime, and the first series I ever subbed, so of course I had to do this.
