you just proved my point, if we only saw danzu fight once and he was using wind nature (lets add Yin and Yang release because of the vacuum style that is a mix of one of this 2 with wind nature), how do you come to the conclusion that he also has earth water and fire?

i assume water and earth from the mokuton but that is not his, its the hashirama cells on his arm and he has difficulty to control it when his crackra is reduced which proves they are not native to him.

still where is the fire coming from?

the torune example was just so it would work better with danzu and fu, i know why he is earth was just making a point, but the same can be aplied to fu, why is he fire again? by your logic he should be earth.

i called it a bug, because i found weird that a ninja that was never shown in the manga/anime to ever use fire nature, to be a fire ninja when he prefers to use wind. Not that he couldnt use fire, but if he goes wind with more frequency maybe that means he has more affinity to wind, wich would make it his main nature over fire, i guess.

same logic as sasuke, he learned first fire, but was more comfortable with lightning as soon as he learned it, so he is categorized as a lightning ninja.

just found it weird, maybe should have placed as a suggestion?

Actually Konoha ninjas are a mix between fire and earth, maybe more to earth (18 if we use all versions of a ninja) over fire (15 if we use all versions of a ninja and including Danzu).

In the case of Danzu its confirmed he uses wind and yin-yang releases, you never see him use fire, so it would make sense to have his nature be Wind. And that is why, in the first post, i asked if he was given fire to work with his own barrier and Fu buff, and I add now that there is no Fire Kage and there is already Gaara with wind nature.

But if that is the case i would like to see consistency when doing it to other ninjas as well, if it is for the ninjas to work as a team like they do in the anime/manga, then Torune could be either fire or lightning, so he could get the buffs and the shields because he also doesnt show any particular afinity to any c*ra nature in the anime/manga. If it is a clan thing, then why is Fu fire while the others from his clan are earth?

That was my point all along, consistency in the process when it isnt actually known the base nature of a ninjas c*ra or they use multiple ones.

But yes, Hinata and Guy are other 2 good examples of this.

regarding your las paragraph, they could introduce the combined natures, and in the programing they would just stipulate that the combined nature ninjas are affected by all the individual natures they would have.

like wood would be buffed by water and earth, and so on.

or as you say add the other individual natures to the ninja itself, which would be easier. still they would have to add the Yin and Yang natures for ninjas like shikamaro and the pains that would have them all, and maybe have ninjas without any nature since they never demonstrated any affiliation with them.

that would be actually awesome
