(I just have a question, are these abilities suitable for the world of Jiu-Jitsu for you? Please tell me in the comments box)
Ability Name: Cursed Aura
1 — Refinement Force
Type: Enhancement
Activation method — step by step:
Kaito begins with a planned training session: sitting or standing in a focused position, practicing slow, rhythmic breathing (in-out) to prepare the flow of the cursed aura within the body. He directs his awareness to muscular contact points (tendons of the hands, thighs, chest), reads the sensation of tension and relaxation, and then intends to "honed" the strength in the muscles to be strengthened. After 2–5 minutes of preparation, he moves on to a motor repetition (lifting weights or combat reps) while maintaining attention on the flow of the cursed aura into the working muscles—and maintaining a focused intention on precision of movement and repetition.
What the user feels when activated:
A warm inner sensation extending from the center of the chest to the working muscles, and a clear awareness of "precision" as mental noise begins to fade away.
Requirements:
It should be a focused training session; do not work outside the training framework.
The level of the cursed aura must be sufficient before starting — low levels may lead to muscle fatigue or serious exhaustion.
Recommended daily time limit: 1 to 4 hours maximum.
Tactical restrictions:
Do not give an instant boost in a random fight outside of training.
Overuse increases the risk of muscle strain.
Long-term, sustained effect requires regular weekly training.
Consumption amount:
Consumes 5% of maximum Cursed Aura for each hour of training the ability is active.
Regular use results in a permanent increase in the size of the cursed aura at a rate of ~5% per week as long as training continues.
Cooling periods:
After every hour of use there is a mandatory 10 minute cool-down period before it can be reactivated.

2 — Blood Link
Type: Emission + Enhancement
Activation method — step by step:
Requires direct physical contact: Kaito touches the ally with the palm of his hand or on the shoulder/chest. During the touch, he closes his eyes slightly, whispers a clear intention to transfer a portion of the cursed aura, and imagines an energy thread stretching between his heart and the ally's heart. After a second or two, a warm sensation appears, traveling through the thread and establishing the bond.
What the user feels when activated:
A soft warmth between their chests, and a sense of an open energy channel. The ally usually feels a quick, warm energy flow.
Requirements:
Initial physical contact is mandatory to establish the connection.
Connection range: up to 20 meters; outside this range, the connection is cut off or gradually weakens.
A maximum of two allies can be linked at one time.
The level of the cursed aura must be sufficient before binding.
Effects and tactical action:
Gives an ally an immediate +30% increase in combat strength.
Directs a portion of the damage an ally takes to Kaito (Kaito takes the damage).
Each damage event recorded to an ally increases Kaito's permanent Cursed Aura stock by a cumulative +10% per event (according to your description).
Consumption amount:
For each bound ally, 10% of Kaito's total Cursed Aura is withdrawn for the duration of the binding (Description: Standard duration 10 minutes per declared consumption).
The ability can be turned off at cast time, but the time implications of the binding are complicated: If the ability is turned off at the sixth minute, there are time rules for reactivation—according to your recipe, it can be reactivated after half an hour as long as an ally is in range, but the countdown starts from the sixth second until the time runs out. (Tip: Treat this as an administrative constraint that requires precise time tracking during combat.)
Operating restrictions for transfer between allies:
When the link is turned off for the first party and then turned on for the second party, the link cannot be re-turned on for the first party as long as the link is enabled for the second party — the link must be turned off for the second party first.
Cooling periods:
After unbinding, there is a 30-minute cooldown before they can bind any new ally or rebind the same ally.
Tactical and psychological notes:
Taking damage may put Kaito in extreme danger; use Link with a Healing or Withdrawal Plan.
Binding an ineffective ally dispels the cursed aura—fix the bond with someone who has a clear benefit.

3 — Echo Heart
Type: Transmutation
Activation method — step by step:
It activates automatically when Blood Bond is activated and damage begins to be transferred to Kaito, or it can be activated voluntarily by focusing on the chest area and exhaling a long breath with the intention of "absorbing" the pain. Before the effect, the user hears a brief internal resonance (0.1–0.5 seconds).
What the user feels when activated:
A sensation of dulling pain, as if wounds were being instantly cleansed; a feeling of a current coiling in the chest and redistributing energy.
Requirements:
Works on self only.
Holds up to three consecutive hits; after that, it requires a recharge for a set amount of time (your description: takes 5 seconds to recharge after three hits).
The cursed aura should be enough to cover the healing cost.
Tactical effects and limitations:
Instantly heals damage transmitted via blood bond, partially numbing the sensation of pain.
In return, Kaito's attack power is reduced by -50% as long as he converts energy into healing.
Consumption amount:
2.5% of the maximum cursed aura per hit converted and healed. (Remember: the consumption may increase if the hit is larger or more serious—as I noted.)
Cooling periods:
Mandatory 1 minute cool down after each use, regardless of the number of strokes processed in that use.
Tactical Notes:
Echo Heart is great for quickly saving an ally but makes your attack ineffective, so you should have cover or a retreat plan after activation.

4 — Equation Box
Type: Conjuration
Activation method — step by step:
The box must first be charged with Kaito's influence on another person (such as a blood bond or a covenant seal). After the initial effect, a symbol appears on his palm or in front of him; upon speaking the command formula, the box materializes from the cursed aura into the physical world.
What the user feels when activated:
A central sensation as if part of the cursed aura is becoming tangible — and a slight throbbing in the palm of the hand when the symbols appear.
Symbols and how to use them (practical):
(+) Plus: Temporarily steals a technique from an affected person. Aura Cost: 10% of the cursed aura is withdrawn (the number adjusts proportionally to Kaito's understanding of the transferred ability mechanism).
(−) Minus: Kaito temporarily halts the use of an ability he owns in exchange for taking over another's; Cost: 15% of Cursed Aura. Minus becomes unusable for a full day after casting.
(×) Striker (Great): When Cursed Aura reaches 30%, grants full mastery of one Nen class, but at the cost of losing Strike ability for a month and a 30% reduction in Cursed Aura for the entire month. (High cost and long-term impact.)
(÷) Division (Large): Creates a clone of the user with 50% of the original's power and is biologically bonded to them; Cost: 15% of Cursed Aura.
Requirements:
The box cannot be rendered "empty"; it must have an initial impact on a person.
No more than two small symbols (+ and −) may be used at the same time.
Big tokens have strict ethical and operational requirements and can be life-changing for the user.
Cooling period:
Small symbols (+, −): 1 minute.
Large symbols (×, ÷): at least 5 minutes, but their long-lasting effects may persist after cooling is complete.
Consumption and tactical notes:
Small tokens typically cost 10–15% of the cursed aura per activation.
Larger symbols consume larger quantities and impose long-term functional losses (loss of power, constant decrease in cursed aura...).

5 — Oath Seal
Type: Manipulation + Emission + Enhancement
Activation method — step by step:
Kaito touches the target or weapon, opens his throat and clearly pronounces the covenant formula with a specific condition, and fine threads of cursed aura travel to envelop the target like a visible seal.
What the user feels when activated:
A feeling of gentle threads wrapping around the palm and hand, and a balance of energy like a seal sticking to the target.
Requirements:
The other party must verbally or implicitly agree to the existing condition (if the affected person is a human).
The request cannot include a condition that would lead to the therapist's murder or suicide.
The seal can only be activated on one person at any time.
Impacts and limitations:
On objects: Makes weapons incapacitated or damageless for a specified period of time (does not apply to objects with a special soul).
To People: Offers instant healing in exchange for a promise to fulfill one future request of Kaito.
Consumption amount:
Common use requires 10% to 20% of the total Cursed Aura per activated covenant, depending on the severity of the cure or the degree of weapon disabling.
Cooling periods:
10 minutes between normal uses.
If the covenant is broken, the cooldown period increases to at least 30 minutes, and severe punishment (loss of the ability to use Nen) is applied if the covenant is broken by either party or by Kaito.
Tactical Notes:
The seal is powerful, but its ethical and operational risks are significant. Don't use it lightly.

6 — Gauntlets of Balance
Type: Conjuration + Enhancement + Transmutation
Activation method — step by step:
Kaito places his hands in front of his chest, the cursed aura gathering around them in circles, then utters a single word: "Sword" or "Shield." The gesture identifies the aspect; the weapon or shield materializes directly.
What the user feels when activated:
A twitching coldness around the palms of the hands, and a noticeable metallic heaviness when the sword or shield is shaped.
Requirements:
Provides a base level of cursed aura to materialize equipment.
Activating advanced features (location swapping, aura hacking) requires time and operating space reserves.
Impacts and limitations:
Sword Side: A katana sword charged with cursed aura lightning bolts capable of penetrating normal aura defenses.
Shield Side: Creates a cloaking field and a position swap field with an ally — cloaking prevents direct attack while camouflaged; position swapping requires an ally and control approval.
Aura Penetration remains active until killed or the sword is stopped for 4 hours (long restriction).
Sending Shield/Invisibility to an ally binds the receiving party to a 30-minute commitment that cannot be released without the sending party's consent (the receiving party must say "Release" to stop it).
Consumption amount:
Sword: 10% of Cursed Aura.
Shield: 5% of Cursed Aura.
Swap Locations: 5% of Cursed Aura per swap (base distance up to 20m; greater distances consume more energy, prescribed maximum 300m).
Cooling periods:
Sword: 1 minute between uses.
Shield: 30 seconds.
Location swaps: 20 seconds between each swap (may vary depending on distance).
Tactical Notes:
The sword is effective against opponents protected by the cursed aura, but heavy use leaves a long-lasting effect on piercing ability.
Swapping positions is powerful for surprise attacks and rescues but requires careful coordination with an ally.

7 — Black Transcendence Mask
Type: Emission + Enhancement + Manipulation + Conjuration
Activation method — step by step:
Kaito utters the phrase, "It is time to purify the wicked and the criminals," with strong intent toward specific moral goals. A mask forms from the cursed aura and covers his face; the sensation is accompanied by an electric chill in his torso.
What the user feels when activated:
A bright, electric coolness runs through the body, and a sharp mental clarity allows one to transcend self-imposed limitations.
Requirements:
Activation requires setting a clear moral intent (target: criminals/villains as defined by subjective standards).
While in the Mask, any use of the Equation Box (other than the Divide ÷ ability) is subject to an additional moral code: no one who has not committed murder may be harmed, and violating this results in the user's death.
Effects:
Allows the resulting copy of the (÷) ability to be called from the equation box while it is active.
Allows three abilities to be triggered simultaneously with a 50% reduction in Cursed Aura consumption for these abilities, and ignores some of the usual synergy restrictions.
Doubles the effectiveness of self-support abilities (e.g., +30% support becomes +60%).
Consumption amount:
The mask charges automatically over the course of its lifetime and requires no additional Cursed Aura cost while in operation. The true cost is time restrictions and the loss of subsequent abilities.
Cooling periods:
The mask works for a maximum of one hour, and after the hour there is an hour of cooling.
After the effect ends, the selected abilities cannot be used for 4 hours.
Violating the conditions increases the cooldown period and may result in harsher penalties (even death in the case of a kill rule violation).
Tactical Notes:
The mask is powerful for operations that require exceeding normal limits, but its ethical risks are high—don't use it without a rescue plan and an ethical alternative.

8 — Acceleration Shoes
Type: Enhancement + Transmutation + Emission + Conjuration
Activation method — step by step:
Kaito utters "Acceleration Time" and directs his awareness to his feet, feeling a small surge of cursed aura spreading through his calf and ankle tendons. The muscle motors shift, producing a noticeable acceleration.
What the user feels when activated:
A slight surge in the ankles and hamstrings, and a clear ability to stretch and spring.
Requirements:
While the boot is active, only two specific support types can be used: "Blood Bond" or "Echo Heart"; other abilities are not available as supports.
Duration of continuous action: 30 minutes maximum.
Impacts and limitations:
Increases speed and flexibility by up to +70%.
Increases kick power by +30%.
Ideal for surprise attacks or quick retreats.
Consumption amount:
Consumes 1% of maximum Cursed Aura per minute of use; so a full 30-minute use consumes 30% of Cursed Aura.
Cooling periods:
10 minutes after the expiration of the period or early stopping.
Tactical Notes:
Use it with caution—30 intense minutes can quickly empty your storage. Don't use it without a clear purpose.

9 — Final Countdown
Type: Transmutation + Conjuration + Enhancement
Activation method — step by step:
It can only be activated when the cursed aura is ≤ 40% and in a life-threatening situation. Kaito says, "This is the end" in a decisive tone. The technique requires a pre-stored aura via a storage mechanism over the course of an entire month (preparation).
What the user feels when activated:
An internal explosion of power sense, a rapid surge of stored cursed aura flowing through the body; sensory perception becomes overwhelming.
Requirements:
Daily storage of a portion of Cursed Aura must be done monthly — the mechanism requires deducting 20% of the daily Cursed Aura for storage during the preparation period.
Activation is only allowed in real life threat situations.
This technique can only be used after one month of storage.
Impacts and limitations:
Recovers all stored Cursed Aura monthly at once.
Grants double the power for 1 hour (exceptional max power mode).
After use, the ability is prohibited for one full year, and attempting to break this prohibition results in the permanent loss of 50% of the Cursed Aura.
Consumption amount:
20% of the Cursed Aura is deducted daily during the monthly preparation period (for storage). Upon summoning, these reserves are replenished at once to be used for power-up (the mechanism assumes reserve accumulation, not additional consumption upon activation, as stored energy is used to increase power).
Cooling periods:
A full week after each actual use.
Tactical Notes:
Ultimate safety net; use only as a last resort.
Planning for protection teams and recovery phases after use is essential because relying on extreme power leaves long lasting effects on the cursed aura's resources.

Physical abilities caused by the "Cursed Aura" (abbreviated as Aura Abilities)
Some physical abilities and skills that she was explicit about derived part of her strength from
Enhanced Physical Strength: Sourced from physical strength and the lifting of internal restrictions + training related to the Cursed Aura. Technically, it grants the ability to perform massive attacks, but requires bursts of Cursed Aura and recovery time after over-strikes. (Your description doesn't mention an explicit numerical consumption amount—if you'd like, I can suggest experimental tactical consumption figures.)
Superhuman Speed and Reflexes: Bound by a
n Inner Gate and powered by Cursed Aura; Restrictions: Maximum speed cannot be maintained for more than 3 minutes continuously, and consumes a large reserve of Cursed Aura.
Strong physical endurance and
Resilience: The product of long training based on managing and stocking up on cursed aura; there are no specific consumption figures in your basic text, but it requires constant energy maintenance.
