Diamond Eye- Warrior of Light (1973)

Kotaro Rai ends up with a magic ring that can summon the magical hero Diamond Eye.   This is fortunate, since Kotaro has stumbled onto a bunch of jewel thieves who turn out to be demons.  Kotaro can hold his own with humans, but against monsters?  He needs an ally.  Diamond Eye is as close to a genie or djinn as Japanese heroes got, so that makes him more unique than most of them.  That is saying something.  He carries the Diamond Stick, which has a wide variety of magical weapons in it.  He uses this to make the demons change back to their original forms.  King Cobra is the boss baddie, and it takes a good half year to stop him.

Diamond Eye is one of my favorite looking heroes.  His costume- or clothes, since he is a genie- is pretty simple.  These days so many costumes are overly complicated, like that is more "realistic".  His weapon is also cool.  The show ran 26 episodes, and was made by Toho. From Wikizilla- Diamond Eye (ダイヤモンド・アイ Daiyamondo Ai), also called Warrior of Light Diamond Eye (光の戦士 ダイヤモンド・アイ Hikari no Senshi Daiyamondo Ai), is a Japanese tokusatsu television program co-produced by Toho and NET that aired from October 5, 1973 to March 29, 1974. It serves as a spiritual successor to the 1972 series Warrior of Love Rainbowman, and is the second in a trilogy of superhero stories authored by Kohan Kawauchi.
