Archery has been used for hunting and combat but now is used more for competitive sports and recreation. Archery took a sharp decline in usage with the advent of firearms. Rowen is said to be a master of both Eastern and Western archery. I'll be honest, I didn't know there was a defining difference in Western and Eastern archery or even that Rowen knew one over the other. The only difference that I've noticed readily is that while Western Archery allows the archer to hold the bow in their off hand, Eastern archery in terms of Kyuudo requires archers to always hold the bow in their left and fire with their right. This might be why in most images you see of Rowen he has his bow in his left hand. A toxophilite is someone keen or an expert at archery.
The Draw
On the left, Rowen is demonstrating a draw that is more akin to the Mediterranean draw and release. It is the most commonly used draw. The draw of the bowstring is different based on western and eastern archery. In fact, Kyuudou has a very specific draw called the torikake which use the thumb to draw. This is different than the most common draw which is based in using three fingers, the fore finger, the middle finger, and the ring finger. The arrow sits between the top two fingers and is then fired. This probably helps to fire the bow in the long run. The torikake has a different idea because it goes along with a very specific idea that "true shooting, certain hitting". The draw also tends to be longer as it is pulled back behind the ear in comparison to western styles. Incorrect drawing can result in hitting the ear or side of the face. Western archery draws tend to go to the ear (in fact, learning archery, I was taught to pull back to my ear for a proper draw). This type of draw is the one he tends to use most frequently as well. 
In both of these images, he's only pulling the string back to his hear, although he is certainly capable of pulling back the string much further. Time, I think, is what dictates how far Rowen draws the string back before firing. As a master, Rowen might simply just process information quickly enough that draw doesn't matter at all. Rowen is actually seen several times fighting, in which he utilizes both this style of draw as well as something similar to torikake in terms of distance. I wonder if the reason for differing draw lies more with the idea of what needs to be done. Something I'm going to cover a little more in-depth in a few sections.
Kyuujutsu
The traditional Japanese martial art of wielding a bow practiced by the Samurai class. Despite samurai being more known for their swordsmanship, the Kamakura through Muromachi periods were known for their warriors being defined by the boy and their skills with it. The warriors with bows during this time period were considered professional warriors and their way of life was referred to as the way of the horse and the bow. The way of the bow declined in the 1500s when the Portuguese introduced firearms. Through this decline, archery became ceremonial and practiced by monks that eventually led to the creation of the new concept kyuudou.
Kyuudou
The basic thing I want to cover about Kyuudou is this idea: true shooting, certain hitting. I feel that the spiritual aspect of this type of archery is part of a meditation that allows archers to focus everything into one shot. This one shot, when done correctly is true shooting and thus true hitting. It is a focused form of aiming that means one should never miss a shot. The point seems to be marksmanship in the idea that spirit and shooting skill come together with no thoughts or illusions. This fits with the idea that "correct shooting is correct hitting" when one shoots correctly, one hits correctly. So the idea is that through mediation and perfection, the arrow will always hit its mark.
Rowen as an Archer
I've mentioned it in other places, but Rowen tends to be no nonsense. In some regard, I believe this has to do with the possibility of his being trained in kyuudou. One would think that his correct shots would be correct hitting. In this idea, I feel that it's pretty safe to say that if Rowen hits his target correctly the first time, that's the only time he needs to hit it. This could also be why he is frequently the first to use his super move at the beginning of a battle. He can also fire at an extremely rapid rate in which the sky is filled with golden arrows, not something that would come easy for someone who wasn't an expert in archery. Now, being the type of person that Rowen is, I feel like overall mastery would be a goal. I do not feel like he could simply be happy with only one type of knowledge about a subject that obviously had more viewpoints. As his virtue is knowledge, I feel like he would do everything he could to try and understand every facet of something. Through practice, I feel as though this would lead him to mastery in both eastern and western archery.
