Hello everyone.
While I was bored at work, I remembered that I always wanted to do a crossover between Super Sent and Magical Girls when I was a teenager.
I thought why not try again in my mind.
The story I came up with is this. A man, who volunteered to test a space shuttle, disappeared due to a cosmic phenomenon.
When he opened his eyes, he was not on earth but in another world. There, he helped the sentai of this other world and he sacrificed himself to protect him, seeing that our hero had a pure heart, he entrusted him with his sentai powers before dying. So our hero made the promise to continue the work of the sentai : Free your planet from the forces of evil.
Later, the villain discovered that our hero comes from another world. He made the decision to conquer the latter.
And when he thought he had triumphed, the villain managed to go to earth, that's when our hero sent a magical animal to earth to find girls capable of defending the earth from the big bad guy.
