Fan Creation Guidelines

Twinkle IP Fan Creation Guidelines (Official Release)

Version 1.3 | July 10, 2025

These guidelines provide all fans and creators with clear, legally binding guidance for fan works. Anyone creating fan works of any kind based on Twinkle (hereinafter "this IP") must comply with the terms of this document and applicable copyright and other laws.

01Scope & Definitions

• Official Materials: Images, videos, voice recordings, 3D models, stream clips, and other assets officially produced by Twinkle.
• Fan Works (Derivative Works): Creative works that re-edit, reinterpret, or adapt this IP's characters, story, imagery, or other elements.
• Non-Commercial Use: Any activity that does not directly or indirectly generate monetary gain, including free online sharing and social media posts.
• Commercial Use: Any activity conducted for profit or in exchange for consideration — for example, selling merchandise, paid stickers, physical sales at events, advertising, or brand partnerships.
• AI-Generated Content: Any work generated through machine learning or generative models (such as DALL·E, Stable Diffusion, LoRA training, etc.) that includes elements of this IP.

02Permitted Forms of Fan Works

Subject to these guidelines, fans are free to create both commercial and non-commercial works in the following forms:

Illustration, comics, animation, memes, short videos, clips, cosplay, 3D models, music covers/arrangements, written works, and more.

Any tools or techniques may be used (hand-drawn, digital, AI-generated, etc.).

2-1. Non-Commercial Fan Works & Publishing

Free to publish without prior application; please include the following notices in the description when posting on any platform:

• a. The fan-work tag "#TwinkleFanArt"
• b. For stream clips, a link to the source stream
• c. A link to an official social media account (e.g. "Twitter https://x.com/vtuber_twinkle")

Failure to include these notices will be treated as a violation of these guidelines; Hatsuhoshi Studio (初星工作室) reserves the right to request corrections or removal. If the creator fails to correct the issue after notice, the work will be treated as infringing and we reserve the right to pursue legal action.

2-2. Commercial Fan Works & Licensing Process

Prior written authorization is required. Please submit the following through official channels:

• A sample or proposal of the intended work
• Expected sales volume/price or business model
• Scope, duration, and channels of use

Hatsuhoshi Studio reserves the right to approve, conditionally approve, or deny any request.

Commercial activity may proceed only after both parties sign a formal agreement, and products/packaging must clearly display "© Twinkle / Used under license."

Unless otherwise agreed in writing, creators may not sublicense authorized fan works to third parties.

03Scope of Commercial Use

Includes, but is not limited to, the following:

• Sale of physical or digital goods (books, merchandise, stickers, in-app purchases, etc.)
• Paid downloads, paid viewing, or subscriber-unlocked content
• Participation in commercial sales booths (including fan conventions)
• Brand partnerships, advertising, or endorsements

If you are unsure whether a use qualifies as commercial, please contact us directly to confirm.

04Commercial License Term, Withdrawal & Termination

• License Term: Scope, use, and validity period are all specified in the licensing agreement.
• Early Termination: A creator wishing to terminate a license must notify Hatsuhoshi Studio in writing at least 30 days before the intended termination date; both parties will agree on how to handle existing inventory and usage.
• After Expiration or Termination: Both parties shall cease use per the agreement; creators must also stop reselling any products involving official Twinkle materials (unless otherwise agreed).

If a creator breaches the agreement, fails to pay fees on time, or commits any other material breach, Hatsuhoshi Studio may terminate the license immediately and pursue legal action.

05Prohibited Content

• Adult or Violent Content: Obscene material, excessive sexual suggestion, extreme gore, or otherwise disturbing content.
• Obscene, Defamatory, Discriminatory, or Denigrating Content: Content that insults or demeans any individual or group, or contains misleading depictions.
• Political or religious incitement, or content involving piracy, fraud, gambling, drugs, or other illegal elements.
• Content that violates the policies of the publishing platform.

06Use of Official & Third-Party Materials

• Official Materials: Limited to materials explicitly marked "available for fan works." Any modification, remixing, or change of purpose requires additional written consent.
• Third-Party Materials: If referencing another artist's or photographer's work, you must separately obtain authorization from that rights holder. Hatsuhoshi Studio bears no joint liability for infringement of third-party materials.

07Fair Use of Fan Works

Implied License Principle: For publicly posted non-commercial fan works that comply with these guidelines, Hatsuhoshi Studio may, on a non-commercial basis (e.g. as stream cover art, social media shares, or periodic roundups), reasonably feature the work and credit the creator by name and link, without additional compensation. Twinkle will only use such works on her own social/stream channels and will not sublicense them to any third party.

Creator Objection: If you do not wish your work to be used this way, please contact us via the official email; we will stop using it within 7 days of receiving your notice.

08AI-Generated Works

• All provisions of these guidelines apply to AI-generated works that include elements of this IP.
• Such works must be clearly labeled "AI-generated" or similarly disclosed when uploaded or published, to avoid misleading viewers.
• If the license terms of the AI tool used restrict commercial use, creators remain bound by that tool's license; Hatsuhoshi Studio is not liable for disputes arising from violations of a third-party tool's license.
• Character imagery, Live2D models, videos, and 3D models may not be used to retrain models or to produce and publish derivative model weights. Retraining and then publicly using, distributing, sharing, or commercializing derivative weights constitutes serious infringement, and violators will be pursued to the fullest extent of the law.

09Handling of Violations & Legal Liability

Works that violate these guidelines will be handled as follows:

Notice to correct → deadline to remove or correct → determination of infringement and legal action.

• Serious or repeat violators: Hatsuhoshi Studio may publicly blacklist the individual and decline any future collaboration.
• Hatsuhoshi Studio reserves the right to pursue civil or criminal action against infringers.

10Appendix

• Legality Warranty: Creators must ensure their works do not infringe any third party's copyright, trademark, patent, or other rights. Creators bear sole responsibility for any disputes arising from such infringement.
• Governing Law: These guidelines and any related disputes shall be governed by the laws of the Republic of China (Taiwan), with the Taichung District Court as the court of first instance.
• Updates: Hatsuhoshi Studio may revise these guidelines at any time due to operational or regulatory changes; the latest version will be published on the official website and take effect immediately.
