How it works:
Ah, here is where things get quite interesting. There are quite the aspects to this amazing Asian stereotype.
From all the varieties of rice and uses, it has been listed that the length of it can go up to 0.20–0.47 inches long, and the thickness of it 0.079–0.12 inches. However, bear in mind that this is still extremely small.
Now, transition over to the human body. Just a simple glance at it allows any trained shinobi to immediately note many the vulnerabilities.
To start simple, there is the ear canal. The ear canal is about 35 mm in length and 5 to 10 mm in diameter. Recall what was said earlier about the size of rice, which only goes up to 0.47. By creating rice from the ground and then using them as small projectiles, one can easily direct a simple grain of rice down the ear canal, which by the way, is connected directly to the nose.
Take a look at this rice, known as Wild Rice. Say that one of these pierced the ear canal and went so far deep that it ruptured the ear drum. This results in excruciating pain, oh, and a high chance of hearing loss, which can seriously hurt an opponent in battle as we gather most of our information from our sight and hearing during battle.
How about not even the ear canal? What about the eyes? Yes, with a proper aim like most trained shinobis are with the shurikens or kunais, one can even direct only two pieces of grain to pierce the opponent's eyes accordingly. The results should be quite obvious and rather painful.
There are also many pressure points on the human point, and much more vulnerable areas, but the main point here is that rice is small, barely noticeable, but can do quite the amount of damage with its size.
Durability and Flexibility
Rice is generally protected by several hulls, or rough outside layers. The first one is known as the chaff, which is the casing of the rice itself. It tends to be rather scaly, serving for a good protection. The second part is generally known as the bran, which consists of combined aleurone, and the main point here, the pericarp layers.
Most of what is edible and grown from the ground share these layers, and one of the main purposes of it is to protect the fruit itself. It is rich in dietary fiber, making it rather course. From this, and how small it is, most physical attacks should not be enough to destroy rice.
The second point to be made is the fact that rice is such an important staple food for the entire world. When mentioned earlier, it would be great for this to be capitalized - the main reason why rice is such a huge part of that particular economy is due to the fact that it is a seasonal crop.
Rice can practically sprout from anywhere, from high places such as mountains, or even sea level itself. By simple use of chakra itself, rice should be able to be formed and grown from nearly any type of terrain that it is not weak to. The plant itself is extremely, extremely tolerant of water.
So, in battle, one can even summon rice from beneath their enemies' legs and attack them in that manner - earth will only empower rice, making it twice as strong due to its qualities and rich soil.
There are many types of rice, and while all of them share similar aspects and qualities, some can be used in different ways. However, there remains two conspicuous varieties of rice.
The first type of rice is mentioned above, also known as Wild Rice. It is extremely thin and long, and can almost be compared to a senbon, however, it is much more durable. This can be used in a more piercing manner and at high speeds or velocities, easily strike the vulnerable parts of a human body.
A second type of rice that is extremely, extremely important to take into account is the sticky rice. The reason why it is sticky is because while most root vegetables contain the two main starch components of amylose and amylopectin, this type of rice only contains mainly amylopectin. This particular starch is extremely water soluble, meaning that it breaks apart under the correct conditions, allowing the molecules to easily bond with others. Then it becomes naturally sticky and can easily clump together to form thick balls of rice that can be utilized in any way possible - such as making walls for defensive, creating it beneath the enemy to trap them with its stickiness, or even causing a huge amount of rice to drop onto the enemy. Because each of the rice is directly connected to the user's chakra, one can break it apart it any time to perhaps transtion into different types of jutsu. All a shinobi needs to make sticky rice is just to add a bit more water chakra.
Because the user is able to summon thousands of grains of rice at their disposal, it makes it hard for the opponent to completely destroy the rice without wide-ranged attacks. Small scale attacks can not always fully get rid of every grain of rice and as long as there is a single grain of rice still floating around, the user can still do great harm.
- Main Release:
By simply combining Earth and Water chakra together, the user can create rice anywhere - rice in its purest form is white basic rice and the user can create as many as they wish, each of the grains directly intertwined with his chakra. This can simply be a wave of grains of rice directed at the opponent and much like the creativity that Wood and Ice allows, the limit is the user's own imagination.
- Alternative Release:
As mentioned before, the limit of this jutsu is basically the user's own imagination. They can create from this pillars of rice, walls of rice, swords of rice...much like how Earth easy to manipulate, so is rice, and each grain is considered a rather dangerous weapon as of itself.
- Advanced Release:
There are hundreds of types of rice in the world, however, some of them can be extremely helpful during battle situations. Take for example, sticky rice, where the user would simply send an extra wave of chakra throughout the rice, allowing the rice to clump together and form a tolerable defense against fire or wind. Also, the extra mass means that the jutsu would be more powerful.
