Dragon Scale Fortress Technique

Through the knowledge of the human anatomy and his research on the human epidermis Kiyoi has developed a technique in which his body is covered in a thick coat of scales like a snake. These scales are as hard as steel and works to protect him from almost all physical attacks. To maintain this technique it can be physically daunting as it requires him to control his muscles and keep a constant flow of chakra to his skin. He can increase the strength of his scales by putting more chakra in to the technique but it can cause him to run out of chakra to quickly so he can only use it in small bursts. The bonus effects of this technique aside from its defensive abilities is that it makes his taijutsu more effective as his body is in a state where its like he is wearing a suit of armor minus the heavy bulky metal.
