Cool but this makes me question why didn't we get one of these blu-ray shorts for Zi-O? Especially with all of the deletrd scenes according to 7.5 episode they could of easily did what the Legend of Alain mini series did a recap of the show with maybe through the eyes of Woz using a combination of Original, stock and deleted footage.

But back on topic I think this might be like Snipe Episode 0 and be prequel exploring Gai and Aruto Grandfather relationship and the creation of the first Humagears.
