Shouketsu. Uchuu Keiji Shaider...how can I not forget the days when I was so excited every Sunday morning watching every single episode. Actually, it is from this tokusatsu show I have come to learn and love the mystery of history - Incans , Pyramids, Rice Terraces craved from mountains and alike. There are some things that you really learn from watching, besides learning a bit of Japanese (phrases at least).
To those who weren't born in the early 80's, Shaider's human form Dai Sawamura is an archeology student who has deciphered some Nazacan hieroglyphics which impressed the Galactic Union Police and given a code name Shaider who some 12,000 years ago defeated the Fuuma empire lead by Emperor Kubilai. When the empire came back to wreak havoc, Shaider also returned. I didn't pay attention to Dai, as I was in my pubescent stage - I was more keen to his partner Annie. You must see her in action to find out why. That's my short history with the show.
