—Spirit Personality: Kurayami takes the personality of someone who believes misfortune is the one sole truth that any amount of good fortune must be balanced out with an equal of amount of negativity, she believes nothing really matters in the grand scheme of things but she absolutely adores her sister Karui as well as her master.

Shikai Abilities: The Weapon Kurayami-Karui is based on the conceptual practice of Karma, Good and Bad, to which the duel blades both hold a concept of karma.

Kurayami embodies the concept of Bad Karma, also known to be associated with Chaos and Destruction, when Kurayami is used, the blade can cut through virtually anything except abilities and concepts known for defense and even then, Kurayami can easily Pierce such defense given a short time, when Kurayami is swung, it increases its destructive force per consecutive hit which gains more and more force damage per hit to the specific object which resets at every 5 Hits or having hit a different target which resets the count.

Karui embodies the concept of Good Karma which is known to be associated with Law and Order, When Karui is used, the weapon can heal damn near any injury sustained by the user which does take a bit of spiritual energy to heal but not all that much, the weapon can heal injuries that would've been extremely fatal ranging from missing limbs to ruptured/missing organs, the only problem that Karui can't do is that it can't heal a destroyed brain or heart as it can't reverse the effects of death, Karui can also be used to heal Allies of their injuries as well to even possible enemies if that is one's desire.

Bankai Spirit Appearance: both spirits are merged again which forms a new being with one sister being the dominant spirit.

-Karui Rengo: Karui Rengo is when Karui is the dominate spirit when activation of Bankai occurs, Karui Rengo would take the form of an older young woman with a beautifully design blue dress that seemed to blow in a gentle breeze, she has pale skin but has a gentle softness when touched by it, the same gentleness a mother would have upon a child, she has long flowy brown hair that is accompanied with gentle blue eyes.

—Spirit Personality: Karui Rengo would take the personality of one would expect with a mother, whom she would protect and defend with her very life and gently lure into a sleep with promises of protection and safety, Karui Rengo would see everyone she meets as an extension of her own child and would comfort them to the best of her ability and assist them as much as she can.

—Spirit Personality: Kurayami Chikara fully embodies the aspect of Bad Karma, for she fully embraces the concept and aspect of Nihilism that no matter what one does, it ultimately doesn't in the end, she wouldn't be all that caring to anyone as everyone and everything is fated to life and die with nothing to show for it, all forms of creation begin and end. Kurayami Chikara has lost the light that her previous counterpart had and sometimes even ignore the call of her master for a chat outside the use of combat.

Bankai Abilities:

Karui Rengo Passive: Life Aura: The User Passively Exudes an Aura that heals and comforts all known allies to the user, healing their wounds to the point that even fatal wounds that normally can't be healed would be healed within the users presence and all known targets would be passively drawn to attack the user instead of any other target that's affected in the range of the aura.

Kurayami Chikara Passive: Death Aura: The User Passively Exudes an Aura in a large range that seems to break down matter at an accelerated rate, inorganic material being affected within the Death Aura will easily crumble into dust as if they are being forcibly pushed through the sands of time and turn into grains of material, any organic creature, humans, or souls, are within the range of this aura, they will begin to feel insurmountable fear to the user and will hesitant to even attack them while desires to run is more palpable.

-Karui Rengo Final Technique-

*-Kami no Kainyū, Kane Ga Narihibiku Mono e/Divine Intervention, To Whom the Bells Toll: The User can unleash in a single blast of spiritual energy to envelop an extremely large radius of 300 Meters, this blast of spiritual energy is filled with highly potent Good Karmic Energy, to all affected within this range, all of their wounds are healed regardless of how severe it is, it's healed and anything that's missing ranging from lost limbs to missing organs is also replaced, the strength of the healing effect of this technique is so strong that even people who recently died for up to 30 Minutes would be resurrected, granting them life.

-Kurayami Chikara Final Technique-

*-Kami no Kainyū, Jinrui no Hakai o Seitei Suru/Divine Intervention, To Enact Destruction of Mankind: The User can unleash a singular beam of spiritual energy to which can be shot in the same velocity of a rail cannon and can be shoot up to a range of 10 Mile away, this beam of spiritual energy is filled with extremely potent Bad Karmic Energy, when shot the blast would travel up to 10 Miles from Point of Origin to which when the blast makes contact with a target, it expands into a massively large explosion which all enveloped in the large red dome of energy, everything is disintegrated regardless of what they are made off, even materials said to be indestructible is erased within the blast of the Red Explosion Dome.

Downside: The ability of Bankai, the user must Will one side of Karma before utilize Bankai and such, when this is done, the effect of the chosen Karma can only be used during the duration of Bankai and can't be switched during Bankai.

The effects of Bankai due to how powerful it is as well as how stressful it is on the users spiritual energy, the Bankai can only last for a maximum of ten minutes during uses and which in between uses, it needs to take 24 Hours to recharge and stabilize for the user to utilize again however attempting to do Bankai during the cooldown will not only stress the effects of the weapon but can also irreparably damage the user and their spiritual energy.
