denied the light

There might be one reason why Diga was denied entry into the Country of Light: Firstly, Diga had a criminal record. 30 million years ago, he and three giants came to Earth and caused all the Ultraman on the super-ancient Earth to die in battle and rule the Earth for a long time. Although they later turned over a new leaf, the Country of Light couldn't tolerate the existence of people who tainted the past. Secondly, judging from the details of history, Diga had lived for more than 30 million years while the Country of Light only had a history of a few hundred thousand years. If Diga entered the Country of Light, Ottle's father would be very embarrassed to address him as Grandpa. Thirdly, it was possible that Diga didn't know about the existence of the Country of Light. After the war ended, he became a stone statue and went into a deep sleep. After his awakening, he had been active on Earth and didn't know about the Country of Light in the universe. Fourthly, Diga's power came from light. The Country of Light was filled with light and all warriors had light. Diga might be worried that he would accidentally absorb the light of others and cause Ultraman of the Country of Light to lose his abilities and die. Fifth, it was also a fact that Ottle's father did not welcome Diga. Diga wanted to cut off the horn whenever he saw it, and Ottle's father's horn could not withstand Diga's attack.

Naruto could be confused. He may not understand why he was denied when he has accomplished so much. He might start to question the system and those in power. This could lead him to have some internal conflict as he tries to figure out whether he should continue to strive for the promotion within the existing framework or find his own path.

Perhaps there are external threats that the village is facing. The leaders might think that Naruto is more valuable in his current position, where he can be used as a front - line fighter. They may believe that promoting him would mean taking him away from the direct combat and strategic roles that he currently excels at, and they can't afford to do that during a time of potential danger.

It could be due to the current situation in the village. There might be threats that required Naruto to stay. Tsunade, as the Hokage, had to consider the overall safety and stability of the village. So, she denied Naruto's request for the training trip to ensure he was available in case of any emergency.
