It could be a former Leaf Village ninja who left due to some sort of disagreement. Maybe someone who didn't agree with the village's leadership or its way of training young ninjas.
Well, it depends on the nature of the missing ninja. If the missing ninja has a vendetta against the Hidden Leaf, they might train Naruto for their own malicious purposes. However, if they see potential in Naruto to bring about change, they could train him to be a better ninja in a more morally ambiguous way. Maybe they teach him stealth techniques that are not part of the normal ninja curriculum in the Leaf Village.
Siegfried was not mentioned in the Dragon novels. Siegfried was a fictional character in the " Dragons " series of novels. He was a powerful dragon king who possessed the power of the Dragon God. His story was very famous in the entire dragon series, but he did not appear in any official dragon novel.
She would likely be trained by some of the village's top ninja. Her father might get Kakashi or Gai to train her in combat skills. They would teach her how to use different ninja weapons and jutsu effectively.
I'm not sure specifically as there could be different interpretations. It might be about the character Siegfried, perhaps his adventures, his heroic deeds or his journey through a fantastical world. It could also delve into his relationships with other characters.
One common theme is the clash of cultures. When Siegfried crosses over into different worlds or stories, his own medieval - like culture clashes with the new one. For example, if he enters a sci - fi world, his sword - fighting skills seem archaic compared to laser guns, but his honor code might be something the new world could learn from.
I'm not sure specifically which 'Erik and Siegfried' you are referring to. There could be many people with these names. Maybe they are characters from a local legend, a family story or a less - known historical event. Without more context, it's difficult to tell their real story.
Since it's about Siegfried, he is most likely the main character. There might also be other characters like the dragon he slays, or characters from his family or the people he interacts with in his adventures.
Another top story could be about their accident. Roy was seriously injured during a performance, which was a very tragic and widely covered event. It was a shock to their fans and the entertainment world at large. Their shows had been so iconic for so long that this sudden turn of events made headlines everywhere.
One common theme is power - up. Siegfried is often depicted as getting stronger or unlocking new abilities. This ties in with the overall power - fantasy aspect of the Highschool DxD universe.
