"L-listen to me... Nekotaro... y-you must stop Dr. Klaus"

Normal Highschool student Nekotaro Mitsumiya was shocked finding his Grandfather bloodied when he got home. Attacked by Dr. Klaus' henchman, Pranza, Dr. Mitsumiya informs his grandson of the existence of the Super Robot "Neko Robo" and its purpose to stop Dr. Klaus' ambitions for world domination. With a Northpolian Crystal beast revealing itself and attacking Tokyo, Nekotaro must undergo a baptism of fire and steel!

And before anyone calls me on it, yes this is basically the plot of the first ep of Mazinger Z, and yes that Kikaiju is a cross between the Doublas M2 and the Garada K7.
