I read the comments in the chapters, and although they have valid points, I also wasn't very clear, especially since I decided on the talents with a friend (Varhram), who helped choose each one. So, I'll explain each of them and try to make sense of it in your minds (I hope I succeed).
With that said, I wanted to clarify the reason behind these talents. Some of them may seem useless to you? Yes, but I'll explain the reason for each one below, so don't judge them before understanding the reasons, unless you know the actions of the person and they were bad overall, then feel free to judge as you wish.
1st - Use of the Five Elements.I've mentioned this before; it's to facilitate the increase in strength, as a ninja will have an easier time learning and controlling the nature that corresponds with their chakra affinity. However, it can still take years to master. Even so, the ninja is not restricted to using only the nature they have affinity with. In fact, when someone reaches the rank of jounin, it's common for them to have mastered a second nature. While it's technically possible to master all five basic natures, it's very rare due to the amount of training and time required, which is why there are only a few known ninjas who have achieved this feat naturally, such as Hiruzen Sarutobi.
This exists to speed up the process I desire, and it's also a great addition to Ryu's arsenal, making him the opposite of any ninja who only uses their affinity with nature.
2nd - Immeasurable Amounts of Chakra.This is very useful because I just wanted someone with talent (though chakra amount can't be classified, my friend and I decided this). Relying on the overwhelming genetics of the Uzumaki and Senju clans is repetitive. Being an Uzumaki, Senju, or Uchiha is very tiresome, especially since not all of them are the same; each Uzumaki, Senju, and Uchiha is different from the other, limiting many options.
3rd - Accelerated Learning Ability.Let's face it, this is a fairly normal talent since naturally, some people learn faster than others in specific fields, but for Ryu, it's in all fields, as he can learn anything and cut the necessary time by half or more. In the Naruto world, there are inhuman geniuses like Minato, who created an incomplete Rank A Jutsu, and Naruto completed it, making it Rank S. If Minato had stayed alive, he could have completed it himself. Now comparing Ryu to Minato is quite complicated, since Minato is a genius, and Ryu is at most a prodigy in all fields.
The main reason for this talent's existence is to help Ryu learn everything about Taijutsu, Genjutsu, and Ninjutsu in an accelerated way. Combined with the 4th talent, it expands the possibilities.
4th - Superior Reflexes and Brain Processing Speed.The main reason I chose this talent is not the ability to dodge before danger gets too close to hurt him, or the ability to think and perform several actions per second. It's the ability to allow the user to learn more. This is combined with the 3rd talent, which helped Ryu master various Jutsu with ease. By using the superior brain processing speed and accelerated learning ability, Ryu was able to process the information from the scrolls quickly and in a way that allowed him to execute the technique on his first try.
5th - Sage Body.Simply put, the Sage Body is for the absorption, filtration, and automatic balance of Natural Energy, similar to the Jugo Clan's ability but more efficient so Ryu won't transform like Jugo. In a way, it's the ever-flowing Senjutsu chakra, but it cannot be used to absorb chakra because it was exclusively made for Natural Energy. So it's pointless to say it can absorb chakra, because THAT is not possible for the Sage Body; it was made solely for Natural Energy.
