Ookami's Yamato

Name: Demon Yamato

Looks:

Description: The Demon Yamato is a solid form of the demon's essence which lurks inside Ookami. When Ookami wields it, his speed is increased a bit, allowing him to swing the blade so fast it appears as though he never removed it from its sheath, if he is using the sheath. When slashed, the blade leaves a trail in its wake that looks like a cut in the space itself, but is really just an effect of the velocity in which the air is cut. Located on the tip of the hilt, is a black diamond. This diamond allows Ookami to channel larger quantities of the demon's energy into the blade. When this is done, the blade erupts with black fire, increasing damage and leaving a DoT (Damage of Time) effect on whatever is hit for about 10 seconds (1 or 2 posts depending) in which it does a small amount of its own damage. The Yamato provides a few techniques of its own that require chakra, but arent considered jutsu. They are:

Judgment Cut
Chakra Cost: 20 per cut
Description: The user will sheath the Yamato and place the sheath by either hip. From there, the user will make a small nudge with the blade, unsheathing it a small bit. When this is done, a large black sphere will appear in the designated area. The user will usually aim it at an enemy, and if the sphere appears around them, they will be trapped inside the sphere. The sphere cannot be destroyed unless hit from all sides on the inside with extreme force. Weather there is something inside the sphere or not, slashes will appear inside the orb, shredding whatever may or may not be inside the sphere. getting caught inside once is not enough to kill someone, no matter what rank, but if hit enough times by it, and can kill someone. Only three spheres can be summoned in a row at a time, after which a 5 second cooldown period (or 1 post) is initiated. The spheres can be summoned three in a row, three at one time, or three slashes in the same one sphere.

Ghost Cut
Chakra Cost: 100
Description: The user will focus on the energy which makes up the Yamato, and make it transparent, thus making the blade appear to glow blue. Once this is done, anything the Yamato cuts will receive no damage, however it can move through any material. Whatever the blade cut will appear to have taken absolutely no damage at all, but once the blade is sheathed, everything that was cut will receive the damage of the cut, but attaining three times as much damage. This technique is used to easily sever appendages, or slice one in half completely. Things like metal, or large rocks and boulders will only receive a scratch however once the blade is sheathed.

Dashing Slice
Chakra Cost: 20
Description: The user will sheath the Yamato, and expel chakra out of their feet in order to dash forward about 3 yards. Once they have stopped dashing, they will swing the Yamato forward, creating a slash in front of them. When this is done, slashes will appear in the path in which they dashed, slicing whatever they passed closely to shreds.

All of these techniques, excluding Ghost Cut, can have the chakra cost removed if performed while the blade has been charged with demonic energy, however this will consume the fire.

Ok. (DoT is Damage OVER time, for future reference )
A sword made of pure 'energy' is pure chakra?
A sword cannot increase your movement.

The sword techniques are conscider jutsu (as they are Kenjutsu). As such, they follow the rules of jutsus. Add proper ranks, chakra costs, etc. to each.

Judgement cut makes no sense, you unsheath the sword and boom suddenly someone/thing is trapped? No.

Ghost cut requires the 'phasing' abilities, you do not have it. Also, the sword, if it goes through something, would make no sense not to cut it no matter what it is made of. How would something obtain 3x damage just because it is delayed?

Hmm, a charging slash. Are you expelling an attack from the swing of the blade? How does one slash shred something? How far can the slash go? etc. etc.

No, no attack you do will no longer have a chakra cost just because of a demonic energy.
Also, demonic energys are very minimal to keep the site regulated. Your lesser demon is nearly useless except when creating backstory, 'forms', MABY a slight power boost, and that is a large maby, etc.
