what about the 1930.
Japan is rising to be an empire, it's eyes are burning bright to expand into the whole world, and the enemies will try to block its effort into world domination.

Enter Masker Rider Seigi, Japan's secret weapon made using unearthed alien artefacts; his past is tragic, his current condition as an empire's weapon used to subjugate the world, and his inner conflicts about it. And oh he's the emperor's most illegitimate secret son.
