I'm personally not a Doraemon fan (It's an okay series, just never watched/read it.), but this interests me. It also gives me a little bit of hope that some manga author somewhere will try to develop a one-shot into the past of the Ginyu Force from DBZ as I think they deserved a bit more backstory than they were given in the series before being completely decimated.
Maybe I am just screaming out because out of all the DBZ characters, my only real favorites were Android 17, then Burter and Jeice from the Ginyu Force.
But enough of that. I will definitely give this a read if and when it is scanlated.
