CBA License
Crypto Baby Animals Derivative Works Guide v1.0
2026 draft (CBA Holder simplified guide)
English summary — not a legally binding translation
The Japanese version is the authoritative and legally binding text. Crypto Baby Animals (CBA) has historically operated without explicit guidelines or terms. This Guide is being introduced alongside the 2026 revision as a CBA-specific, simplified guide, and is operated under a licensing framework separate from Shikibu World.
Notice on document name and terminology
This page was originally published as "CBA License v1.0", but the title was changed to "CBA Derivative Works Guide v1.0" together with the 2026 revision addendum. The word "license" too strongly suggests an officially granted right, which conflicts with the (unofficial) derivative-work positioning of the project.
The scope of rights, conditions, and operational rules remain unchanged. Holding one CBA NFT still grants derivative-work commercial-use rights to all 999 pieces.
Overview
At a glance
SCOPE
Hold 1 CBA NFT → commercial-use rights for all 999 pieces
CBA is a 999-piece limited collection. Holding even one CBA NFT grants the right to commercially use all 999 character designs — including those you do not personally hold — for fan art, merchandise, LINE stickers, social media materials, and similar derivative works.
Conditions
Hold ≥ 1 CBA NFT
Annual revenue under JPY 200M
Permitted characters
All 999 CBA pieces
All 34 animal types
Out of scope
Character-centric businesses
Companies with revenue ≥ JPY 200M
Section 1 — Scope of this Guide
This Guide sets forth the conditions under which TAKER Inc. ("Company") grants persons holding one or more NFTs ("the NFTs") of the NFT project "Crypto Baby Animals" ("CBA") operated by the Company (such persons being "Holders") the right to engage in derivative-work use of the characters represented by the NFTs ("the Characters").
This Guide is a separate licensing framework from the Shikibu World Copyright Guidelines and Terms of Service, and applies to CBA-only Holders who do not hold any Shikibu World NFT.
Section 2 — Permitted character range
On the condition that a Holder holds one or more CBA NFTs, the Holder may engage in derivative-work use of all 999 character designs in the CBA collection within the scope set out in this Guide, regardless of whether the Holder personally owns the specific design used.
This is a CBA-specific scope and differs from the Shikibu World Copyright Guidelines, which limit permitted use to the specific NFT design that the Holder personally owns.
Section 3 — Conditions for personal and commercial use
Holders may engage in personal and commercial use of the Characters within the scope of Section 2, provided all of the following conditions are satisfied.
- The group-consolidated annual revenue of the Holder or any group to which the Holder belongs is under JPY 200 million.
- The Characters are used in a supplementary or decorative manner, and not as the central element of the Holder's business (i.e., not a "character-centric business").
- The use does not fall within the prohibited acts set out in Section 6.
- The Holder complies with the display obligation set out in Section 8.
The revenue test follows the same group-consolidated standard as Section 11 of the Shikibu World Copyright Guidelines.
Section 4 — Cases outside this Guide
The following cases are outside the scope of this Guide. Please consult with us individually via the BUSON STUDIO contact form (buson2025.com).
- Commercial use by corporations with consolidated annual revenue of JPY 200M or more
- Specialty stores, OEM brands, hero-image advertising, and other use that places the Characters at the center of the business
- Large-scale rollouts (national chains, large platforms, etc.)
- Other matters that the Company determines cannot be handled within the framework of this Guide
Section 5 — AI use restrictions
Restrictions equivalent to those in Section 9 of the Shikibu World Copyright Guidelines (Special provisions on AI use) apply to the Characters.
Prohibited AI use
- Distributing, selling, or displaying AI-generated content as, or including, the Characters
- Creating, distributing, or selling LoRA or other learning models trained on the Characters
- Creating or distributing voice synthesis models in the name of, or in a manner similar to, the Characters
- Operating AI-VTubers or AI chatbots using the Characters
- Mechanical, mass generation of images of the Characters
Permitted AI assistance and post-processing
- Automatic coloring of human-drawn line art
- Automatic translation and proofreading of existing text
- Image resize, upscale, and noise removal
- Auxiliary background generation (where the Characters themselves are human-drawn)
Section 6 — Prohibited acts
Holders must not engage in the following acts when using the Characters.
- Use that significantly damages the dignity of the Characters
- Combination with content that violates public order and morality, or that suggests an association with anti-social forces
- Combination with specific political or religious claims
- Discriminatory content based on race, gender, nationality, religion, age, or other attributes
- Use that infringes the intellectual property, privacy, or portrait rights of third parties
- Impersonation of the Company's or the Characters' official accounts
- Intentional exploitation of loopholes in this Guide or related rules
Section 7 — Prohibition of derivative-work NFT issuance
Equivalent prohibitions to Section 12 of the Shikibu World Copyright Guidelines apply to CBA.
Holders must not newly tokenize as NFTs any image, video, audio, or other content that depicts the Characters, and must not issue, list, sell, or transfer such NFTs. This prohibition covers all forms of tokenization, regardless of token format (full on-chain, off-chain, edition, generative, etc.).
However, secondary trading (transfer, sale, etc.) of existing Crypto Baby Animals NFTs themselves remains permitted.
Reasons for the prohibition
Crypto Baby Animals operated without explicit guidelines or terms when released in 2021, but in light of the rapid evolution of the technical environment in the NFT industry, the Company has determined that this Guide must address the following newly materialized risks, and accordingly the issuance of derivative-work NFTs is prohibited in full.
- AI-generated content has become a real threat
The accuracy and proliferation of image-generation AI and LoRA learning models has advanced rapidly, and at the off-chain image level "human creation" and "AI output" can no longer be reliably distinguished. Section 5 prohibits NFT-ization and commercialization of AI-generated content, but if derivative-work NFT issuance were permitted, output from LoRA models could enter the NFT market disguised as human creation, effectively nullifying the AI provisions of this Guide. - Loss of IP control through AI-agent NFTs
The combination of ERC-6551 (Token Bound Accounts) — which gives an NFT its own wallet — with AI agent technology has spread rapidly, and "wallet-bearing NFTs" capable of autonomously posting on social media, distributing content, allocating revenue, and transacting with other agents are now operating at scale as real services. Examples include AI-idol NFTs on Base with 500,000+ TikTok followers running 24/7 autonomous broadcasts, and AI analyst NFTs on X that autonomously publish market analysis and pay revenue back to holders, all operating without human intervention. HTTP 402-based autonomous payment protocols (e.g., x402) further allow AI agents to settle USDC and other stablecoin payments via smart contracts in seconds (over 100M cumulative transactions on Base alone as of 2026).
If derivative-work NFT issuance were permitted, the Company could not technically prevent Holders from turning such NFTs into AI agents that act as autonomous representatives of the Characters across social media, broadcasting, and commerce. Once deployed on-chain, AI-agent NFTs cannot be stopped or controlled by the Company because of the irreversibility of smart contracts. This produces a state in which, from the public's perspective, "AI-fied CBA characters are speaking, selling, and broadcasting on their own" — and consistency of personality, brand-damage response, and the ability to halt during incidents are all left to the derivative NFT holder. Unified IP management would effectively become impossible. This is the most severe and concrete new risk. - Operational difficulty of conditional permission
In drafting this Guide, conditional-permission options ("ban only generative", "permit small-scale only") were considered carefully, but the technical and practical line for "generative" or "small-scale" was found to be extremely difficult to draw (e.g., distinguishing 100 manually issued items from 100 auto-generated ones, setting edition thresholds, detecting distributed issuance via multiple accounts). To avoid the operational complexity, perceived unfairness, and loopholes that conditional permission would create, we have opted for a simple, full prohibition.
* If the Company in the future provides an official NFT issuance platform or other framework, this Section may be revised to fit that framework. For individual issuance requests outside this Guide at the present time, please consult BUSON STUDIO.
Section 8 — Display obligation
For commercial use, Holders must comply with the following display obligation. The official assets (fanfic logo and 1-NFT license certificate) shared with Shikibu World are used.

* The license certificates contain a QR code linking to shikibuworld.com. Because CBA uses a single-tier guide, the 1-NFT certificate is used regardless of the number of NFTs held.
2. Display location requirements
| Location | Where to display |
|---|---|
| Website | Display the certificate within the first view or in a persistently visible header. Footer-only display is not acceptable. |
| Physical store / kitchen car | Display the certificate at the entrance, on the vehicle, or at the point of product display |
| Products / merchandise | Display the fanfic logo on packaging, tags, or sales pages |
| Social media account | State in the profile that the account is a "Crypto Baby Animals derivative-work project (unofficial)" and keep this clear in the pinned post or recent posts |
| Social media images | Place the fanfic logo in the bottom-right at a visible size (≥ 5% of the longer image edge) on every post image that uses the Characters |
| Social media videos | Display the fanfic logo for at least the first 3 seconds, or persistently throughout the video |
3. Visibility (preventing confusion with official channels)
The certificate and fanfic logo must be displayed in a position clearly visible at the moment a visitor or buyer encounters the content, so that visitors do not mistake the project for "Crypto Baby Animals official".
- State explicitly in the first view (top of the website, store entrance, social media profile, etc.) that this is a "Crypto Baby Animals derivative-work project".
- Identify the operator (personal name, business name, service name) so it is clear who runs the project.
- Do not use words such as "Official" in the project, site, or store name.
- For websites, footer-only display does not satisfy this requirement.
* If the Company determines that this requirement is not met, it may, under Section 10, request that the display be changed.
4. Required "(unofficial)" wording
For commercial use, the following standard wording must be displayed alongside the fanfic logo. This prevents visitors and buyers from mistaking the project for "Crypto Baby Animals official".
Required wording
"(unofficial)" or "derivative-work project (unofficial)"
5. Examples of text wording
Use the following as a reference for first-view, profile, and similar text. Always include "(unofficial)".
Recommended
- Crypto Baby Animals derivative-work project (unofficial)
- A derivative-work project by CBA Holders (unofficial)
- Fan-work merchandise (unofficial) / Crypto Baby Animals derivative activity
Not allowed
- "Crypto Baby Animals Official" (official wording prohibited)
- "CBA Official Project" ("Official" prohibited)
- Names containing "Crypto Baby Animals" without "(unofficial)" wording
6. Official directory registration
Holders engaged in continuous commercial use are required to register on the Holder Projects directory. The directory is shared between Shikibu World and Crypto Baby Animals.
Section 9 — Use after transfer
If a Holder transfers all of its CBA NFTs and its holdings reach zero, the license under this Guide terminates. Fan art, merchandise, LINE stickers, and similar materials created during the holding period must, in principle, not be sold or published after transfer. Individual treatment may be arranged by consulting the Company.
Section 10 — Amendment of this Guide
The Company may amend this Guide in the future. Amendments take effect upon publication on this page. Material amendments will be separately announced through the Company's social media or other channels.
