Kengiryu/tokukae

Tokukae (shield change) is the fourth kengiryu technique, and the only purely defensive form of the seven. It effectively relies on moving a sword so fast it becomes more like a solid shield, the most basic form being to spin a pair of swords in a circle in front of the user. More advanced variants involve sequences or movements to block from other angles quicker, and even to strike an incoming projectile or weapon directly to deflect it.
