Call, write, and beg? Apparently, this is a fairly recent acquisition for enoki... they've renamed sasuraiger "wonder six" and baxinger
AFAIK, NEITHER of those two series are available on DVD... and you'll be paying through the nose (amongst other orifices, most likely) IF you ever managed to find VHS versions.
Galactic Whirlwind Sasuraiger "spun off" of Galactic Gale Baxinger which spun off of Galaxy Cyclone Braiger. Fitting, given the theme in the names, eh?
Braiger = Love, American Style
Baxinger = Happy Days
Sasuraiger = Joanie Loves Chachie (okay, Sasuraiger's better than THAT, but you get my point)
