Danzo does not have just 1 chakra nature, he has Wind, Earth, Water, and Fire Release, as well as Yin and Yang Release. just like Sasuke who has a few natures he c*e but is counted as Lightning even though most Uchiha's are fire. they are In the Land of Fire so it makes sense most clans that originate from there are fire.

Torune is a bug/poison user and they are classified as Earth for whatever reason, maybe cause shino actually does earth nin-jutsu or earth and bugs go together. Either way he is by no means a Fire or Lightning, most non nin-jutsu ninjas are listed as earth such as Lee.

Also remember we only really seen Danzo fight once which he was using Wind against someone using Lightning, it is possible he was using it to counter the lightning. this last thing is just a guess with no actually proof to support it but the previous 2 are both easy for you to google and see for yourself.

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.

Okay, and where is the bug ?

Glyrin, there is something you did not yet understood about the Naruto universe.
All characters have only ONE Chakra Nature, that Nature is the basis of all their Chakra.Danzo has Fire Chakra Nature, but he his capable of launching several Ninjutsu Styles which is not only dependant on your own Chakra Nature.
For instance, some Gekkei Kenkai and Gekkei Tota (Blood Limits) allow the user to release 3 DIFFERENT Style attacks, for instance, Mei Terumi, she has attacks which have Lava Release, Lava Release is a mix of Chakra Styles, not Chakra Nature.

Chakra Style is the same as Chakra Release. You can look for it an inform yourself on this theme. :)
We choose to adopt Chakra Style+Chakra Nature typpings for this game.

There is no bug. From what i read, he talks about Danzo that has fire nature instead of wind.

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?

Sasuke was confirmed in both anime and manga to have Lght Chakra affilation, the same as Naruto was confirmed to have wind.

Personally I would be more surprised by Hinata and Guy being Lighting, as they have no connections to this element whatsoever. Earth would match them much better.

Danzo was given Fire, I assume, due to his belonging to the Land of Fire. Most people from this country are Fire natured, so if chakra nature is not specified, they are either assigned their country element, or something that matches them the most.

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.

Well, I personally don't see Danzo working well with Naruto though :v

Kotoamatsukami barrier also wouldn't make sense to buff wind nature.

Anime logic, he could be either fire or wind, but game logic he is definitely more fire.

Torune was not a team fighter, he prefered solo duels. He and Torune were both rather not cooperative characters, they more often split up then work together from what I remember (could be wrong, it's been ages since they last appeared in anime xD)

The most inconsistent ninja is as of this day, Pain. Each path has different chakra nature, while none used any. Nagato is Fire in CN from what I remember, but he only used one chakra nature which is either water or wind (bad memory, but I think that when Yahiko was alive they used elemental ninjutsu under Jiraiya's training).

Ninjutsu that is used by a ninja is not an indicator of what chakra nature he is. Sasuke first learned fireball as his clan was profficient in Fire Style, but his affilation was Lght, which is also his nature in game.

As I said earlier, when ninja's nature was not estimated in anime/manga, it had to be "made up" by developers, to match the ninja's characteristics the best.

Hinata is lighting, Guy is lighting, Kabuto is water, and Kekkei Genkai ninja are not dual natured, even though they should be. To this day I wonder why isn't Hashirama both Water and Earth natured, as well as Haku being Water and Wind.

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
