Vocal Box

Manipulation.

By touching your throat and applying nen you can slightly alter your vocal cords to sound different. You can only mimic the voices you are familiar with. The process takes around 10 minutes or longer depending on how familiar. If your able to touch the throat of someone else and listen to them speak while touching your own you can bypass the time and familiarity requirements to change your voice. You can also do this to another individual as well changing there voice. This ability can be used to mimic more then just voices but takes longer the more complicated the sound and less familiar you are with it.

Now if you want this to be stronger make a vow similar to the vow of silence where you vow to never use your real or natural voice ever again.

Real-Booting "Those eyes, whose are they?"

Basic summary of this hatsu. Used AI to format and help with it. There more to this ability but this basically the rough draft/summary. Inspired by Chaos Head anime which contributed to me being obsessed with eyes. Also I have aphantasia so it mentions that here and there because I was developing abilities that would or should work with it. 🤷 Thank you for your time, even if you skip.

"Those eyes, whose are they?" (その目だれの目?) is a high-tier, horror-themed Specialist Hatsu designed to completely bypass the visual-rendering limitations of aphantasia. Instead of using a "mind's eye" to conjure or transmute Nen, the user utilizes the subconscious minds and primal fears of their victims to serve as the "rendering engine" to materialize physical, reality-warping threats.

Here is a short summary of how the Hatsu operates:

### **Nen Classification**

Primary Type: Specialization (100%)

Sub-Types Used: Conjuration (80%), Manipulation (80%), Emission (60%)

The 5 Activation Conditions

To "tag" a target and link their vision to your network, you must complete these five steps within a rolling 24-hour window:

Direct Gaze: Establish direct, locked eye contact with the victim.
The Keyphrase: Speak the phrase clearly for them to hear: "Those eyes, whose are they?"
The Zetsu Seal: You must be in a state of absolute, completely defenseless *Zetsu* during the entire tagging process and while actively using the Hatsu.
Blindness Activation: Close your own physical eyes to activate the connection, leaving your body blind in the real world.
The 24-Hour Expiration: The target must have been successfully tagged within the preceding 24 hours, or the link naturally dissolves.

-The Absolute Vow (Counterplay): If any victim ever utters the keyphrase back to you, the Hatsu instantly shuts down for them, and they gain permanent, lifelong immunity.[1]

The Core Mechanics:

-The Security Monitor Station: Upon closing your eyes, your Specialist Nen constructs a conceptual, text-based "Security Monitor Station" in your mind. This allows you to "channel surf" and view live visual feeds streamed directly from the physical eyes of up to 100 tagged targets.

-The Paranoia Leak: While actively focusing on a target's stream, you slowly leak a trace of Manipulation and Specialist aura into their visual cortex. This triggers a progressive paranoia scale, making them feel constantly watched, causing severe anxiety, and eventually forcing them to hallucinate a grotesque, shadow-stalker entity.

-Delusion Synchronization: If multiple tagged victims are physically close, their paranoia "networks" together, creating a shared delusion.

-Real-Booting (The Wavefunction Collapse): Once the total Delusion Synchronization value meets or exceeds 240\% (e.g., three tagged victims in the same room whose paranoia levels hit 80% simultaneously), the shared delusion "real-boots" into objective reality.

-Universal Visibility: The stalker instantly materializes as a real, physical, highly aggressive Conjured/Specialist Nen Beast. It is no longer an illusion; everyone—even non-Nen users—can physically see, touch, and be attacked by the monster.

-Subconscious Stat Generation: Because your aphantasia prevents you from visualizing the monster's details, the beast's physical combat parameters are calculated directly from the victims' own subconscious fears. The more intense and detailed their terror, the more lethal and indestructible the real-booted beast becomes.

Extra info

It doesn't say it in this summary but one of the tells of if someone is infected with this hatsu is that when using it on them their eyes change to reflect your eyes example a girl with brown eyes infected by this hatsu now has blue eyes if the hatsu user eyes are blue. This allows for them the chance to naturally say the key phrase "Those eyes, whoes are they?" To break free. This hatsu went through like 3 different hatsu concepts and this is the one I decided to post. The original one was just using this as a spy network to spy on people but the more you spied on them the more paranoid they become.

Event Horizon

2nd post not the best at this yet. Ai helped me with the concept not sure if this counts as emission 🤷 just liked the format.

Hatsu Name: Event Horizon

Nen Category: Transmutation (100%), Emission (60%), Enhancement (80%)

The Concept: The user projects their En to establish a spherical field of aura around themselves. By utilizing Transmutation, they alter the properties of the aura within this En field to mimic Absolute Density and Weight, creating a highly controlled zone of localized gravity under their complete command.

Core Techniques

-Gravity Well (Singularity): The user compresses their En down to a highly localized point (such as a 1-meter radius). By maximizing the transmuted density of the aura in this tight zone, they create a crushing gravity well that instantly pins enemies to the ground or collapses physical weapons under intense downward force.

-Planetary Shroud (The Domain): The user expands their En over a wider area (such as a 10 to 20-meter radius). The gravity inside this larger field acts as a constant physical "pressure" (similar to spiritual pressure) that heavily slows down the movement, physical strikes, and reaction speeds of anyone caught inside.

-Gravitational Pulse (Repulsion): By releasing a sudden, explosive burst of Ren within their active En field, the user creates a shockwave of reverse gravity that violently repels incoming physical attacks, weapons, or enemy projectiles away from them in all directions.

-Weightless Vector (Buoyancy & Flight): The user can transmute their immediate personal aura to have zero density, neutralizing the Earth’s natural gravity to float effortlessly. By creating a high-density "Sovereign Singularity" at the edge of their En, they can selectively pull or "tow" their body in any direction at high speeds, enabling precise three-dimensional flight.

Vows & Restrictions (Resolve Multipliers)

-The Vow of Self-Subjection: The user is always physically subject to the exact same gravitational forces and G-forces they project. If they multiply the gravity within their field by 10x, they must also endure that exact weight. To survive the crushing strain of their own domain, they must continuously use Enhancement to physically reinforce their bones and internal organs in real-time.

-The Inverse Law: The crushing power of the gravity is inversely proportional to the size of the En field. A wide-area field provides a light slowing effect, while a highly compressed, close-range field produces absolute, bone-crushing pressure.

If I was a specialist 🤔

This is my first time posting. I love coming up with hatsu concepts I have dozens and this is one I came up with after finding this forum. It's a rough draft and I had help from AI to put it in a easier format (told it to make it a character sheet) here is the character concept and hatsu. May be confusing. Sorry for the * is a result of copy and paste. Also the bracket numbers where links so don't worry about them. I'm obsessed with 2 concepts. Concept 1 immortality and concept 2 storing power (like immortal culivators from Korean and Chinese manwhas) hope you enjoy reading. If you have any questions I'll try and answer them.

### **Original Character Sheet: Asura**

#### **Character Profile**

* **Name:** Asura

* **Aura Type:** Specialization (leaning toward Conjuration and Manipulation) [1]

* **Technical Proficiency Rank:** Excellent [1]

* **Occupation:** Contract Hunter [2]

#### **Primary Hatsu: The Heavenly Bank (天の銀行)**

* **Nen Type:** Specialization, Conjuration, Manipulation, Emission

This high-tier Specialist Hatsu operates on a highly balanced system of financial contract law [3]. It allows Asura to act as a "Nen Central Bank"—storing, leasing, lending, and permanently harvesting the Hatsu of others under highly formalized and voluntary covenants.

* **The Vault (The Daiten):** Inspired by cultivation, the vault is a separate pocket dimension conjured inside Asura's body around his navel (his lower *daiten*) . Stored aura and raw Hatsu within this navel vault are completely isolated from physical decay, environmental degradation, or natural leakage . When a client successfully opens an account, they are given a physical checkbook conjured from Asura's Nen and blood [4].

* **Savings Account:** A specialized account where deposited Nen generates more Nen over time ``.

#### **The Transfer Mechanism**

To execute any financial transaction within the bank, a registered user must utilize one of two primary transfer mediums:

**The Digital Portal**: The client logs into the online banking page via the internet and authorizes a direct digital transfer of Nen.
**The Paper Checkbook**: The client writes down the transaction details on a conjured check, specifying the amount and whether they are depositing or withdrawing. Once signed using blood or active aura, they must physically rip the check out of the book, which instantly activates the transfer of Nen.

#### **The Interest Generation Rule**

Rather than manufacturing Nen from nothing, the bank's compound interest is fueled by a symbiotic siphoning mechanism ``:

* **Leaking Nen Siphoning**: The bank passively captures the tiny, continuous stream of aura that naturally leaks from the aura nodes of the account holder or nearby living creatures ``.

* **Ambient Capture Triggers**: This siphoning mainly takes place while the client is asleep (when conscious aura control naturally drops) or when they are in heavily populated areas (capturing cumulative regional aura runoff).

* **The Banker Multiplier**: The rate of interest accrued by each account scales with the size of the network. The more active bankers currently registered in the system, the higher the passive interest rate each individual account earns.

#### **The 6 Account Registration Conditions**

To establish an account and activate the checking functions of *The Heavenly Bank*, Asura and the client must strictly fulfill these **6 conditions** in sequential order [3]:

**Condition 1 (Dual Records):** Asura must set up a record-keeping system with both an off-the-books, IRL paperback ledger and a website (the bank page) [5].
**Condition 2 (The Explanatory Limit):** Asura must explain how his Hatsu works to the other party. He must inform them that he is completely unable to attack or harm them or he will die, and he must let them know that he has to answer any Hatsu-related questions truthfully or he will die [6].
**Condition 3 (Voluntary Setup):** The other party must set up an account with Asura (either online on the bank page, or in person on paper). The client cannot be under any influences like mind control or coercion to set up the account ``.
**Condition 4 (Identity & Signature):** Asura must obtain the user's legal true name (or what they believe to be their true name) and their signature. This signature must be given using aura or blood (typing with aura if making an online account, or writing with aura or blood if on a checkbook) ``. It can be given in person or online, but must contain one of these two mediums.
**Condition 5 (100% Structural Clarity):** Asura must make his checkbook and website 100% easy and clear to understand for depositing and withdrawing Nen, including clear information on the VIP card and its benefits [5].
**Condition 6 (The Handshake):** The agreement must be finalized with a physical handshake of mutual consent ``.

#### **Overdraft, Zetsu Siphoning, & Compounding Interest**

* **The Overdraft Option:** Accounts have an overdraft feature, allowing users to withdraw more Nen than they have deposited [7].

* **The Grace Period:** The debtor has exactly one day (24 hours) to pay back the overdraft before the Zetsu curse takes them over [7].

* **The Delayed Trigger:** The forced Zetsu penalty does not activate automatically out of thin air. It only triggers when the debtor comes within range of their physical checkbook, or when they next log into their account online [8].

* **Repayment Forced Zetsu (Aura Siphoning):** Once triggered, the target is slammed into a state of absolute Zetsu [7]. The Zetsu siphons their aura: they remain in Zetsu for as long as it takes their body to naturally generate and pay back **double** what they overdrew, with the siphoned aura going directly into the *Daiten Vault* [7]. Repayment time is represented as:

Where:

* T_{pay} is the duration of the forced siphoning *Zetsu* state in hours.

* P is the overdrawn principal amount of aura in Aura Units (AU).

* R_{gen} is the target's natural, biological aura regeneration rate in AU per hour.

* **The Compounding Penalty:** For every day (24 hours) the overdraft remains unpaid prior to the Zetsu trigger (e.g., if the debtor runs away, hides their checkbook, or refuses to log in), the debt accumulates an additional 5% compounding interest daily [7]. This is calculated as:

Where:

* A is the total final debt to be repaid.

* P is the overdrawn principal.

* t is the number of days spent past the overdraft limit before the Zetsu trigger.

* **Asura's Banker Overdraft Rule:** As the physical locus of *The Heavenly Bank*, Asura is subject to the same overdraft rules as standard bank members, but with two severe mechanical overrides to balance his central position [6]:

* *Automatic Trigger:* Asura is structurally unable to run away from or hide his overdraft [9]. The Zetsu siphoning penalty activates **automatically** and immediately after his 1-day (24-hour) grace period expires, completely bypassing any range or login triggers [9].

* *Quadruple Repayment (4x):* To lift his forced Zetsu state, Asura must naturally generate and pay back **quadruple (4x)** his overdrawn principal amount of aura instead of the standard double (2x) repayment cost [7]. This siphoning repayment time is represented as:

Where:

* T_{pay(Asura)} is the duration of Asura's forced siphoning *Zetsu* state in hours.

* P is the overdrawn principal amount of aura in Aura Units (AU).

* R_{gen} is Asura's natural, biological aura regeneration rate in AU per hour.

#### **The VIP Credit Card**

* **The VIP Upgrade:** Trusted clients can upgrade to a gold VIP Card, which acts as a limit-free credit card with no overdraft fees or compounding interest [7].

* **The Collateral Vow (Hatsu Staking):** To receive this card, the other party must "stake" their Hatsu as collateral, explaining exactly how it works (including all rules, conditions, and weaknesses) to Asura [6].

* **Post-Mortem Harvest:** Upon the VIP's death, their Hatsu is permanently taken, bypasses natural dissipation, and is stored in Asura's *Daiten Vault*, **but only if they have been a member of his bank for at least one year** [10].

* **Hatsu Borrowing:** VIPs can access the online page to browse the catalog of stored Hatsus, letting them lease and borrow any Hatsu stored in the vault on loan.

#### **The Bankruptcy Feature**

This ultimate fail-safe and post-mortem protocol activates upon Asura's death, or if he actively declares it [10]:

* **Bankruptcy Declaration:** If Asura declares bankruptcy while alive, he has exactly 1 hour left to live [11]. During this final hour, he gains full access to use all of the massive Nen reserves currently stored inside his *Daiten Vault*.

* **Rebirth as a Nen Beast:** Upon his death (whether from declaring bankruptcy or being killed by other means), his residual willpower activates post-mortem Nen [10]. He is reborn as a sentient **Nen Beast**.

* **Nen Beast Rules and Limitations:**

* **Invisibility:** He is completely invisible to all ordinary humans and anyone who cannot see Nen ``. He is physically unable to interact with creatures that cannot see Nen.

* **Hatsu Freeze:** His primary Hatsu, *The Heavenly Bank*, permanently enters his navel vault. He is physically unable to register new clients or open new accounts.

* **The Life Support Anchor:** Asura lives as a Nen Beast only for as long as he has living, active bankers registered in his system. The moment he has zero living bankers left, he dies permanently.

* **Personal Use Restrictions:** While in Nen Beast form, Asura is no longer considered a "user", but he still maintains his own personal checking account for private use under heavy restrictions:

* His personally stored Nen is static and **does not gain interest**.

* He is strictly forbidden from asking for or receiving loans from other active users.

#### **Asura's 7 Personal Vows & Restrictions**

To grant his banking system its absolute, reality-warping authority, Asura has bound himself to **7 strict personal vows** [3]. Breaking any vow (except Vows 1, 5, and 7, which carry their own custom systemic punishments) results in instant death [6]:

* **Vow 1 (The Banker Vow):** I vow to never turn down a person who is interested in becoming a banker. If I break this vow, I enter a state of Zetsu for exactly 1 month per existing banker. While I am in Zetsu, my personal Nen is stored and distributed into the accounts of all my active bankers.

* **Vow 2 (The Setting-Up Honesty Vow):** I vow that during the set-up and process of an account, I must answer any questions about my Hatsu that the user may have with 100% honesty. Breaking this vow results in death [6].

* **Vow 3 (The Account Preservation Vow):** I vow to never delete a user account unless I have proof of them killing another user. Breaking this vow results in death.

* **Vow 4 (The Pacifist Vow):** I vow to never fight a user. Breaking this vow results in death.

* **Vow 5 (The VIP Vow):** I vow to always offer a VIP Card when registering someone or before finalizing their account. If I break this vow, all of my stored Nen in my personal account is instantly transferred to the account of the individual I forgot to offer the VIP Card to.

* **Vow 6 (The Treasury Isolation & Life-Risk Overdraft Vow):** I vow to never personally use the Nen of another user. Breaking this vow results in death [6].

* *The Overdraft Exception*: I am strictly forbidden from personally utilizing the stored Nen of any other user *unless* my personal life is in immediate, mortal danger. Overdrawing my own account under this specific survival condition does not count as a violation of this vow, and I remain subject to my custom 4x auto-overdraft penalties.

* *The Zero Balance Restriction*: However, if I overdraft my account and any single bank member's personal balance drops to 0 as a result of my overdrawing, it will be treated as a direct breach of this vow. I must constantly and precisely gauge my overdraft limits and exercise absolute caution, as accidentally triggering a 0 balance on any user's account through my overdraft will result in my instant death.

* **Vow 7 (The Vault Depletion Vow):** If my vault ever runs dry (no aura/Nen), I vow to supplement it with my lifespan [11]. If I am a Nen Beast as a result of bankruptcy and my vault goes dry, my Hatsu collapses and I die permanently.
