Seven Swords of the Mist & Other Kiri Owned Artifacts

Name: Kubikiribōchō
Item Rank: X
Material Rank: X
Materials Used: Unknown
Description: The Executioner's Blade is a huge broadsword that was forged in the shape of a butcher knife. The blade itself is two meters long, with a handle that is two feet in length. There are two holes in the blade, a circle close to the top and a semi-circular one nearer to the handle. The former is used mostly for a strap while the latter is used primarily to decapitate a downed foe, thus giving the blade its name. The handle is detachable to make carrying it a bit easier.

The blade represents superior craftsmanship and cutting ability being the sharpest and most durable blade out of all the Seven Swords of the Mist. Because of this the Material Rank is +1 rank higher than the other Seven Swords, capping out at X-rank Material Rank.

In addition, given the heft of the blade the user receives a +1 tier to Strength regarding strikes using the blade.

The enchantment in this blade makes it indestructible. The blade can still be damaged and broken down, however the handle and 2 ft. of the blade will always exist. When the blade is laced in blood it can fully be repaired to its full length giving the sword the opportunity to be restored back to its original form.

Requirement: C-tier Strength (two-handed) | B-tier Strength (one-handed)

Name: Hiramekarei
Item Rank: X
Material Rank: S
Materials Used: Unknown
Description: Hiramekarei features a wide, flat blade with two curved indentations near its base, creating a sort of cross-guard. Two handles are connected to one another by a short length of cord, earning it the title of "twinsword" (双刀, sōtō). The overall sword looks like a flounder fish in shape. When not in use, Hiramekarei is wrapped in bandages.

Hiramekarei is capable of storing up to 150 CP of the user's chakra. When a new user claims Hiramekarei they must feed 150 CP worth of chakra before utilizing the blade. After the blade is fully charged for the first time the owner will have access to learn its technique noted below.

The user may utilize their own chakra if Hiramekarei runs out of its storage. However, when using their own chakra directly from their pool they must spend an additional 10 CP per activation, and 5 CP per upkeep as the user's direct chakra is not attuned to the nature of the blade, unlike that which is stored prior.

Technique:

Requirement: C-tier Strength (two-handed) | B-tier Strength (one-handed) | B-tier Stamina

Name: Kiba (Fangs)
Item Rank: X
Material Rank: S
Materials Used: Unknown
Description: The swords have been imbued with lightning, granting enhanced cutting power in a manner similar to the high-frequency vibrations of lightning-based chakra flow (Increases the cutting power of chakra flow by +1 rank, capping out at S++.) It is this capability that has resulted in these being claimed as the sharpest swords in existence. Even without lightning, they are very dangerous in battle, able to be used in combination with agile spinning movements, sweeping through the targets while the user also rotates. This, combined with the jagged nature of the blades, allows for more damaging wounds inflicted.

The user can  perform their Lightning Release techniques without hand seals. They also boost the user's attack power to the highest limit, which allows them to perform high-level Lightning Release techniques with a minimal cost of chakra (-2 Rank deduction for Lightning Release.). These blades can channel the user's own respective lightning techniques or conduct natural lightning. While meant to be used as a pair, the user can perform similarly with only a single blade. They can also be connected at the hilts to form a larger double-bladed sword, increasing its versatility as a weapon. They are able to perform various powerful techniques, such as to manipulate the blades from afar, leaving their hands free while attacking the opponent at different directions simultaneously.
Requirement: Must have Kenjutsu. B-rank Coordination.

Name: Samehada (Shark Skin)
Item Rank: X
Material Rank: S
Materials Used: Unknown
Description: Samehada is a large sword, roughly comparable in size to the Executioner's Blade. The actual blade itself is comprised of downward-facing scales along the entirety of its length up until the hilt. The base of the hilt is attached to a skull. The scales can be changed in size however the more Samehada absorbs chakra from enemies, the more it will grow. At its apex the weapon takes an appearance similar to actual shark fins along with a mouth manifesting at the tip of the sword.

Samehada is unique in that the weapon is sentient and has a taste for chakra. It is able to distinguish between different "flavors" of chakra and has a relentless appetite that can only be sated with those with a large chakra pool. Samehada will reject those who do not meet its requirements and will naturally try to return to its owner if a bond is formed.

As the blade is made up of scales, it inflicts injuries through shredding or shaving what it comes into contact with, rather than just cutting the object in question. This flaying effect is similar to a shark's skin, hence the sword's name. While it ordinarily remains rigid, Samehada's hilt is able to stretch and bend to great extent, allowing the weapon to be used like a flail. To supplement the blade's offensive capabilities, it is able to extend its scales to spikes, and protrude spikes from its handle. Samehada can also be used in conjunction with Water Release, leading to the sword glowing with chakra.

Samehada passively consumes the user's chakra. This is represented by a tier decrease in the user's total Stamina pool while the weapon is actively being wielded by the user. Samehada is capable of absorbing 12 Stamina Points from an opponent when the blade comes into contact with the opponent's body (including flesh, clothing, and armour). Samehada has a maximum capacity of 130 Stamina Points and it cannot absorb beyond that amount. Samehada grows so large that when it is over 100 Stamina Points, it requires S-Tier to wield it with one hand and A-Tier with two. Samehada will absorb such chakra even as it manifests as cloaks or protective shields that encapsulate the enemy's body such as Tailed Beast forms. It is possible via the Bloody Mist Absorption Technique to absorb chakra from a distance.

Bloody Mist Absorption Technique

Spoiler:

Samehada will grow in size as it consumes enemy chakra. When Samehada has consumed over 100 Stamina Points in a given thread, it will be sated to such a degree that it will cease eating the user's chakra removing the tier penalty while wielding it for the remainder of the thread. Samehada generally cannot eat ambient chakra meaning chakra that is expelled from the user's direct person (fireballs, water domes, etc) the sole exception to this are Tailed Beast Balls.

Due to its voracious appetite, Samehada is drawn to those with large chakra supplies, allowing it to be used as a quasi-sensor. Samehada will instinctively sense the chakra signatures of those with A-Tier and higher Stamina that are within a 300 meter radius. Samehada will inform its owner of the location of those individuals.  

Fusion Stage 1

By investing 500 experience into Samehada its wielder may form a bond with the weapon. Samehada's familiarity and constant feeding off the owner's chakra will essentially bring the two closer together. This grants the wielder the ability to fuse with Samehada. This adds any Stamina Points that the weapon has absorbed to be added to the user's total pool. In this fused mode the weapon also does not passively consume the owner's chakra thereby removing the tier penalty to the wielder's Stamina. The fusion also grants the wielder a healing factor capable of healing serious and life threatening injuries within three posts. However, the fusion is still incomplete at this stage and as a result the user may not absorb enemy chakra nor may they make use of Samehada's sensory abilities while in this mode. The user can remain in this fused state for up to 8 posts per thread.

Fusion Stage 2

By investing another 500 experience into Sameahda its wielder may increase the power of that fusion. This completes the merger with Samehada and grants the wielder and even greater shark-like appearance. The user will grow fins and webbed hands allowing them to move in water with considerable ease. The are granted a unique boost of a tier to Speed and Coordination for the purpose of moving through the water. The user also has the ability to extend spikes from his body and may now absorb chakra (under the same parameters discussed above) when others come into direct contact with him or her. The wielder may also make full use of Samehada's sensory abilities while in this mode. The user can remain in this fused state for up to 12 posts per thread.

Samehada will generally remain loyal to its wielder if they meet the requirements for using it. However, if lost or stolen it will make no significant effort to return to its previous owner. If the wielder reaches stage 1 of fusion their bond will be strong enough that the weapon will be resistant towards others who meet its requirements while the wielder still lives (the weapon can sense if its master is still alive no matter the location). If the wielder reaches stage 2 of fusion their bond will be so strong that only the death of the previous owner will allow it to cooperate with a new owner.

Samehada dislikes fire nature chakra and while it will consume it, doing is excruciatingly painful.

If Samehada is hit by or forced to consume a C-Rank amount of Katon it loses 10 Stamina Points, If Samehada is hit by or forced to consume a B-Rank amount of Katon it loses 30 Stamina Points, If Samehada is hit by or forced to consume a A-Rank amount of Katon it loses 50 Stamina Points, If Samehada is hit by or forced to consume a A-Rank amount of Katon it loses 80 Stamina Points.

If at any point the amount of Stamina Points held by Samehada reaches below zero it will begin to eat directly into the wielder's reserves (with the tier penalty in effect). The amount of stamina points lost by the wielder will correspond to the amounts listed above.

Debuffing the wielder's Stamina can cause Samehada to turn on the wielder. However, once the user reaches Fusion Stage 2, Samehada will stay with the wielder so long as the debuff is not permanent.  

Requirement: A-Tier Stamina is required to wield the sword absent that the user must have an external source of chakra that is fairly significant in order to entice Samehada to cooperate (ie a Bijuu) This sword can be wielded by either both hands with C Rank Strength, or one hand with B Rank Strength. Samehada will eject spikes from its hilt to prevent anyone with lesser chakra from wielding it.

Name: Kurosawa
Item Rank: X
Material Rank: S
Materials Used: Unknown
Description: The sword is fairly long and thin, and has a rectangular hand-guard and a long hilt wrapped in bandages. The katana style blade is double-edged and due to its craftsmanship, makes it an ideal cutting blade.

Kurosawa is crafted to be used by the best swordsman. Any swordsman who wields this blade is considered the grand master since they were able to retrieve this from its previous owner. When wielding the blade the user feels the superior craftsmanship in their hands resulting in +1 tier to Coordination regarding handling.

As it was a blade made for Samurai it has a special affinity for the Iaidō technique. When using Iaidō the cost of the technique is reduced by -1 rank which stacks upon the regular Kenjutsu reduction.
