I loved Samurai Pizza Cats growing up, and would tape as many episodes as I could. I just ate it all up. That Blast Zero shot for the moon on a lark and got a response of "hold on, I know a guy..." that led to this is just crazy in its own way. That they aren't just sidelining the Japanese side of things either is a nice-- That they made a trailer for Kyatto Ninden Teyandee as well really shows care and commitment most wouldn't even consider. And while the franchise is very niche in Japan in comparison to its cult classic status it has in the West, there's still plenty of responses I've seen that are glad to see this and feeling that nostalgic love.
Heck, in the last (non clip show) episode, Yattero even said goodbye to the audience with the hope that he'd see them again some day!
