Well, this is a thing that I decided to do on my own, so here it is. This is the long lost promotional oneshot featured in Tele Manga Heroes from way back when Decade began in 2009. The only thing more complicated to find than this is the long lost promotional manga for All Riders VS. Dai Shocker, but hopefully I’ll find it one day… Or maybe someone has it?
Anyway, yes, here Decade passes by because… well, that’s what he does, at least in this manga. I guess. Hmh.
