The King of Braves GaoGaiGar

The King of Braves GaoGaiGar (勇者王ガオガイガー, Yūsha Ō Gaogaigā) is a Japanese anime television series produced by Sunrise's internal "Studio 7" division alongside Tokyu Agency.

The series follows the exploits of two protagonists: One is a cyborg named Guy Shishioh, who pilots the titular Gaogaigar, and the other is a mysterious boy Mamoru.

About seven years later, high school astronaut Guy Shishioh is aboard the space shuttle Spirits when it collides with an unknown object bound to Earth.

Despite being mortally wounded, the lion rescues him and he returns to Earth, holding a mysterious green jewel that Leo Shishioh uses to revive him as a cyborg.

while Satoko Shimonari performed the series' ending theme "Itsuka Hoshi no Umi De" (いつか星の海で, "Someday, in the Sea of Stars").
