Agulu is a blue giant, representing the power of the ocean. Like Gaia Altman, Aguru Altman was born on the earth. Unlike Gaia's red light, it symbolizes the blue light of the ocean.
Similarly, Agulu is also the existence of Fujimiya, which is transformed by its own will and completely integrated with light. At first, because of different beliefs, Agulu had to fight both monsters and Gaia; Later, the two became friends and joined hands to fight against the invasion from the "broken roots".
Extended data:
Fujimiya Hiroya
When he first appeared, he was 22. He was a genius scientist who refined Venus and created the optical quantum computer-Crisis. But he got the wrong answer because of the infection of his shattered body (later his physical condition became worse and worse). Aguru Altman, like Ultraman Gaia, is a "human Altman" born on the earth. His real identity is that he suddenly left the rattan palace of "an alchemist" a few years ago, just like a brother in my dream.
At the beginning of the plot, Fujimiya thought that human beings were the chief culprit in the destruction of the earth. Because of this different concept, he has to fight against disillusionment and Gaia Altman, who protects mankind. Similarly, he became Altman by his own will. In the later period, Fujimiya Hiroshi, who realized that human beings would change this point, also found what he really wanted to protect, regained the light of the ocean, and joined hands with Takayama Gamu to defend the peace of the earth.
