This is from the profile of the greatest chad,
Yujiro Hanma. I used him as an example because he has had this rating for a long time now, it has been widely accepted on the wiki and hasn't been controversial ever, and also, he's purely based on physical feats and not anything like magic, which is very good because he would make the best thing for a comparison.
Extraordinary Genius (Yujiro is known as the single most dangerous being on the planet,
mastering virtually every martial art known to man including ones only passed down through noble blood and
single-handedly defeating the entire U.S. Army during the Vietnam War with nothing but his bare fists. He is extremely analytical, being able to decipher and fully utilize virtually any technique after seeing it once and knows over twenty languages.
Now, I will not address two things here:
1. Defeating the entire U.S. Army during the Vietnam War with nothing but his bare fists: Not addressing because this isn't combat IQ but outclassing. This dude is Tier 7, which is higher than or equivalent to some of the nuclear bombs and has a speed against which bullets cannot do crap.
2. Knows over twenty languages:
Ziad Fazah knows 59 languages, so not even a feat for Extraordinary General Intelligence, which is cool because his intelligence achievement on his profile is purely due to combat IQ.
So, the first feat of knowing virtually every martial art known to man including the ones only passed down during noble blood, and due to his extreme analytical nature and knowledge, being able to decipher and fully utilize virutally any technique after seeing it once, Kiyotaka has a feat similar to this.
-> Kiyotaka mentions that his body has been trained in countless situations, and therefore, he has gained the experience enough to connect any information gained and mimic it to his own expertise and connect the information between the sports which he has learnt.
(Already sent the scans for it.)
Yujiro also has an extremely in-depth knowledge of human anatomy, even more than skilled surgeons, high tech x-ray machines or talented medicine men. He's able to use this knowledge to exploit his foes' weaknesses and make fights last longer. He has extensive knowledge in many fields, such as cooking, biomechanics, biology, chemistry, arithmetic, zoology, and more)
Not even comparison to Kiyotaka if we talk about pure knowledge. Kiyotaka would canonically possess more knowledge than experts, which would be the equivalent of just the anatomy part, not to mention Kiyotaka's knowledge in much more fields which includes multiple fields of sciences, politics, liberal arts, linguistics and economics.
With this, I will also establish that Kiyotaka has similar analytical abilities here.
Can detect the physical conditions and weaknesses of a person with 100% accuracy by glancing at them - Kiyotaka also characterized the physical strength of his opponents based on their muscle mass and the way they walk. Kouenji, someone whose powers were readily absorbed by Kiyotaka in his deductions in Y2V3, is stated to have an ability which allows him to detect someone's physical abilities via the heat emitted by their body.
As for Analytical Prediction, Kiyotaka in Y1V7 was already predicting the entire fight with Ryuuen and even mentioned that everything was going according to how he planned it and that, he was considering each and every possibility. Though yes, here, he is talking about how he planned and predicted everything about what happened in about literally three light novel volumes of content.
And he also has Upper Limit Analysis and Intuition prediction, something which Yujiro doesn't possess and would falter in comparison here because he can be countered via unpredictability (which I genuinely saw in a thread), while Kiyotaka cannot because his predictions are just out of thin air upon analyzing his opponent's upper limits and doing the information analysis in that way.
Further, Yujiro knows techniques that accelerated develop his single stats, and similar to this, Kiyotaka has his adaptability where his learning speed increases in a pre-dip sigmoid way.
Hence, I think while Kiyotaka falls in comparison to Yujiro in terms of pure knowledge of martial arts techniques, but both are similar in bodily experiences (
Kiyotaka has fought in about 15000 battles upon just the White Room schedule and that's just his kid self) and having the Bodily Kinesthetic enough to mimic moves entirely in instants and absorbing information. Further, Kiyotaka has supreme demonstrated analytical nature inside fights and actually has feats for strategizing even battles, while Yujiro is still driven by his motivations.
So yes, I bet on at least an "At least
Genius" to probably even an "
Extraordinary Genius" rating, the latter, of course being the one which I think more suits his feats imo, due to both being a biased Kiyotaka fan (I admit), and an SCD scaler from 3.5 years about these feats never being replicable IRL and outclassing the upper world limits fairly easily.
