Diga Ultraman as a classic childhood god, has left a deep impression on countless people, among which the protagonist Hiroshi Nagano played by Hiroshi Motoyashi Motoyashi is also very perfect, enthusiastic and full of justice, but after watching Digha's TV drama, I don't know if everyone will have such a question, whether it is the light that chose Dagu, or Dagu accidentally inherited the light, which is like the problem of chicken or egg first, this point in the play is actually a conflict.

First of all, let's look at the first episode of Diga, and Yu Pity says very clearly at the end that there is only one way to revive the giant, and that is to turn the great ancient into light.
From the previous plot, it is known that The Time Machine of Pity is the product of thirty million years ago, and all the things she predicted have happened, Such as Golzan, Merpa and the Pyramids, etc., then what Pity said can be seen as an inevitable result, that is, the Great Ancient must become light.
In the second episode, Yu Pity explains that Dagu's body contains the DNA of a super-ancient warrior, so he can transform into Diga Ultraman, and even bluntly say that Dagu is Diga Ultraman, and also says that Dagu is both light and human, and Pity actually did not fully explain the words.
Then came the forty-four episodes, Masaki Keigo brought us a very interesting explanation, the reason why Dagu can become light is because he has the genes of ultra-ancient warriors in his body, and it just so happens that Masaki Keigo also has this DNA, so Dagu is not a special existence.
From Masaki Keigo's words, it can be understood that he has his own opinion on the successor of light, and Masaki Keigo found the video of the resurrection of the stone statue from the TPC file, and accurately analyzed the time point at which the great ancient became light.
According to Masaki Keigo's words, it was an accident that Dagu was able to turn into light completely, but Dagu was present at the time and happened to have the genes of a super ancient warrior, and then Dagu obtained the Divine Light Rod, and through the Divine Light Rod he could transform himself into a giant of light, in his eyes, Dagu was just the one who happened to be selected.
When the time came to the finale, The Divine Light Rod of the Great Ancient turned into ashes and disappeared after fighting Gatanjae, and the most direct and most likely statement is that there are no monsters that can threaten the earth, so Diga's duty as a guardian spirit has also been completed, and naturally there is no longer a need for the Great Ancient Battle.
On the whole, Dagu is more like the person who was chosen by the light, and Masaki Keigo, who also has the genes of a super ancient warrior, because the wrong heart becomes an evil Diga, so if Masaki Keigo has a righteous heart like Dagu, can it be considered that he also has the possibility of becoming Diga, or other giants of light?
