As reported by orendsrange.com, recent scans have revealed that Narutaki, nemesis of Kamen Rider Decade will be playing a role in the much anticipated Ressha Sentai Toqger/Gaim crossover special.
His exact involvement isn’t known, but from the images we do know that he’ll have is own monkey puppet and will be appearing along side a monster called Mouraroid.
As this special is a prequel to Heisei VS Showa, this most likely means that the whatever causes the events of Heisei VS Showa, it’s probably Decade’s fault.
