What If Junki Takegami Were Ressha Sentai ToQGer's Head Writer
I once thought that Naruhisa Arakawa should've been Ressha Sentai ToQGer's head writer because of Akibaranger. Another writer worth mentioning is none other than Junki Takegami. So why would I mention him as an alternative? If you did some Super Sentai research for the late 90s up to late last decade it'd be obvious. On the other hand, for the sake of others who don't know why I could talk about it why I imagine him as its head writer. He was involved with not just one but two shows that were obviously public service announcements. In the year 1999 he was assigned to be Kyukyu Sentai GoGoFive's headwriter. In 2008 he was assigned as Engine Sentai Go-onger's headwriter. He's also the head writer of Denji Sentai Megaranger which might also help though I'd stick to the fact he's involved with GoGoFive and Go-onger for this post.
Instead of Braneworlds, maybe Takegami would have created the concept of Imagination Worlds that the ToQGers would save. If you think about it the Shadow Line aim to make our world suitable for their living conditions. That's just similar to Gaiarc wanting to pollute Human World so they could migrate to it. I could imagine that he would actually create the plot where the ToQGers seek to save certain Imagination Worlds from the influence of the Shadow Line. He may even write public service announcements about train safety tips and OTHER safety tips at the end of every episode. There's many possibilities on how he would have handled a series that deserved its award last October 14, 2017. It's so sad really that he didn't get the opportunity to handle it even as a secondary writer!
Pretty much, I think he would have been another fine choice as the series' head writer.
