Description: The personal katana of Hotsuma Hayabusa, Akujiki, is an ancient and cursed blade, said to have consumed the souls of men for centuries. It is said, "He who wields Akujiki, wields absolute power." Akujiki possesses the terrifying ability to indefinitely enhance its destructive power by consuming chakra. Thus, whosoever uses Akujiki shall forever be cursed with an unfortunate fate; in order to sustain the blade's hunger, those who wield Akujiki must dedicate their entire lives to the slaughter of any and all beings that possess chakra, and then they must be devoured in their last moments. Despite Akujiki's incredible power, it was possible to seal the demon blade by using fuinjutsu to contain its power. However, because seals of this nature are not indestructible, they must be vigilantly guarded, lest the seal become undone and allow Akujiki to run rampant. Hotsuma has taken it upon himself to end the bloodstained legacy of the blade.
Ariake Seal
The Ariake seal's formula runs along the length of Akujiki and forms a thin barrier along the blade equal to S-rank. The chakra emitted from the barrier is made to not only contain the blade's power but also serves to counteract sealing techniques of equal rank and below. Originally, this seal was a countermeasure put in place to prevent it from being undone by those whose only wish was to gain power. The chakra within the formula activates when the Ariake Seal comes within short-range a foreign sealing technique. As the sword comes near the opposing sealing technique, the chakra stored by the barrier forcibly enters the foreign seal's activation mechanism and destroys the chakra within preventing the seal from activating or remaining active. The Ariake Seal can counteract one sealing technique A-rank and below three times per battle. To sustain this seal requires no concentration on the user's part, but it does drain a small portion of the user's chakra to sustain itself. As mentioned the true purpose of the Ariake Seal is to prevent the sword from draining the user's chakra substantially. But by sacrificing a move, the user can choose to undo the seal and allow the true nature of the Akujiki to come forth. The unsealing happens passively, and once unsealed, the blade begins to draw on large portions of the user's chakra seeking to consume them and inflicting them with the blade's curse. This seal may be redone at the cost of a move and three handseals.
Evil Eater
Akujiki shares the name with the curse placed upon the user in exchange for its power. As the Akujiki consumes a large amount of the user's chakra, the chakra becomes dense and visible in the form of a blood-red hue completely coating the blade. The chakra exuded from the blade is a manifestation of its hunger and can absorb one S-rank or below technique's chakra within short-range once per turn while also granting the user's kenjutsu +20 damage while unsealed. For every technique absorbed, the Akujiki empowers itself by consuming the chakra and exuding a destabilizing shockwave meant to make consuming additional chakra easier. This chakra enters the body and prevents the use of elemental techniques for a single turn. However, this shockwave affects all within short-range of the sword including the user and thereby afflicts them weapon's curse. During this time, the chakra consumption of Akujiki is halted as it engorges itself on the absorbed chakra until the -40 chakra cost cannot be sustained. If less than 40 chakra was absorbed, the user's own chakra makes up the difference. If Akujiki consumes the user's chakra while in this state they will be unable to perform genjutsu due to the strain. Should the user die while in possession of Akujiki it will then forcibly consume and seal the user's chakra within it, leaving only the husk of their body which is rendered to dust.
Note:
Requires Adv. Fuinjutsu to use.
Akujiki is indestructible, but cannot be used to defend against jutsu on its own.
Once the Ariake Seal becomes undone, the user may redo the seal at the cost of a move. The seal can only be undone for a maximum of 4 turns per battle.
