The World of Generation 3 is a nice, peaceful, safe place to live, with no form of danger of any kind. At least, that’s what everypony living there thinks. They can be excused, though. They’ve never met the dangers lurking in the darkness. But those dangers aren’t content with just lurking anymore.
An armor suit. A transformation. A mutation.
Minty takes on a weighty responsibility. Lily finds one placed upon her. Thistle doesn't know what’s happening to her.
Three realms. Three Riders. Countless enemies. One word. “Henshin!”

Is it Heisei Rider or Kamen Rider? I'm confused.

"Heisei" is the era designation for Kamen Rider seasons starting in the year 2000, distinguished from the earlier "Showa" era seasons reaching back into the '70s (they're named from the current and previous Japanese emperor eras that they roughly match up with). Heisei seasons are basically the ones with several Riders and a hundred form changes each, as well as having planned season-long stories and season-unique gimmicks, whereas most Showa seasons are almost the same with only one Rider with a single form each.
...Huh. This looks fascinating. Shades of multiple different Rider shows, all blended together? I approve.
