Each of weapons he uses is marked with a single symbol that binds them to his blood. Anyone who holds the weapons without his consent will be either electrocuted or they will spontaneously combust. The symbol also helps him locate the objects if he ever loses them in the head of the moment.
Eikichi has just a large variety of staffs as he does blades. His staffs are ancient and powerful, some of the prominent features were remade or reinforced on them in order to increase their durability and their link with him. Some of the metal on the staffs were re-forged with drops of his blood. TO further strengthen the bond between him and his weapons. They only work to his touch, or to the touch of those with his blood.
The staffs each have different functions. Some of the staffs are even reinforced with hidden weapons and blades, making them potent against the dark. Silver and bronze are prominent in these staffs since they repel lesser spirits quite easily.
Eikichi’s blades are rather unique. Each blade has a symbol marked into the hilt or the blades metal itself. His blades do not limit themselves to short hand weapons and two-handed weapons. He has a variety of blades not only for thrusting but for other things. He carries dual handed weapons in order to have the advantage over some opponents. He also carries a set of throwing knives and stars. A range of daggers that he wears on him and a few he had hidden along the folds of his clothing.
His weapons are not all magical, though all the blades have one magical property because of the rune inscribed on them by him. They are all rather significant to him, either because of their rare value or personal significance. Some of the blades were been forged by him, or forged again with drops of his blood. This was done so that only he could control his blades, and only those with his blood in their system can hold them.
These are trinkets he had collected that can be used as weapons. Though they do not classify as a blade or a staff, and there are rather few of them so they are lumped together in the same place. There are a variety of gauntlet weapons and hidden weapons. With certain attachable claws and hidden blades, not to mention magical trinkets built in and crafted by him to make them stronger.
