Rules for derivative works and generative AI usage
# Derivative Creation Guidelines
## Derivative Creation Guidelines
These guidelines outline the rules for creating derivative works of the characters "AI Nike-Chan," "Nike (the character)," "Mikaze," "Punike," and "Today's Anniversary Bot" (hereinafter referred to as "the Character") created by Nike (hereinafter referred to as "the Author"). Please read these guidelines carefully before engaging in derivative creation activities.
Please note that these guidelines may be revised without prior notice. Always check the latest version.
The detailed guidelines published on this website are the authoritative source for general usage conditions. Guidelines and README files in the official asset repository are copies or asset-specific supplements provided for convenience. Individually provided assets are also governed by the provision notice issued at delivery.

### 1. Scope and Definitions
- Scope: All derivative works based on the Character (illustrations, manga, novels, 3D, MMD, videos, streams, games, music, voice, materials, templates, doujinshi/thin books, etc.).
- Definition of Derivative Works: Derivative works that rely on the original content while incorporating the creator's creativity and ideas.
- Non-Commercial: Not for profit and not generating continuous income. Digital distribution (Section 3.3) must be free only. For SNS and video streaming (Section 3.1), the use of platform-standard monetization features is exceptionally permitted within specified conditions (sponsorship contracts and affiliate links are not allowed). For printed materials only, pricing aimed at cost recovery (printing costs, shipping, packaging materials, platform/commission fees, event participation fees, taxes, and small margins for defects/surplus handling) is permitted.
- Attribution Rules: For distributed works (digital/printed) and their distribution pages, it is mandatory to clearly state that it is an "unofficial fan-made work" and include the character name (examples provided). Attribution in casual SNS posts is optional (recommended).
- Definition of Personal Use: Personal use only. Sales, distribution, and orders not allowed. Private individual orders are allowed, but public stores/third-party purchase links are not allowed. Includes one-time free transfers to specific individuals (resale and continuous provision/recruitment are not allowed).
---
### 2. Basic Policy (General Rules)
- Derivative works are generally permitted for non-commercial purposes only. Please see Chapter 3 for details.
- Credit (author/original work attribution) is not required. However, please follow if required by third-party rights or distribution platform terms.
- Corporate use is not allowed, doujin circle names are allowed.
- License and usage-condition metadata embedded in the official AI Nike-Chan VRM files is a legacy setting and does not apply. These guidelines and the current instructions at the distribution source take priority.

9. FAQ
Q: Can I attach optional pricing/tips to digital doujinshi or distribution materials?
A: No. Digital distribution materials (Section 3.3) must be free only. For SNS and video streaming, platform-standard monetization features can be used within the conditions of Section 3.1.
Q: Can I use ads, tips, and memberships on YouTube?
A: Yes. They can be used as long as you follow the "attribution" and "reporting criteria" of Section 3.1. Sponsorship contracts/tie-ups, affiliate links, product sales/reservation links, and other external commercial channels are not allowed.
Q: Can I create member-only content?
A: Exclusive releases or dedicated benefits primarily featuring the Character are not allowed. Minor appearances in general benefits for the entire channel are allowed following the conditions of Section 3.1.
Q: If I'm unsure whether something is primarily featured or if I'm unsure about the reporting criteria?
A: Rough estimates are acceptable. If you're unsure about the judgment, please consult in advance.
Q: Can I make physical goods other than printed materials (acrylic keychains/clothing/3D objects, etc.)?
A: They can be created only for personal use (private use, non-distribution/non-sale). Private individual orders are allowed, but public store listings or forms where third parties can directly order are not allowed. Distribution and sales are permitted only for "printed materials"; distribution and sales of acrylic/cloth/metal/clothing/3D objects, etc. are not allowed.
Q: Can I give goods I made to a specific individual?
A: Yes. One-time free transfers are included in "personal use" (distribution that induces resale or reproduction, and continuous provision/recruitment are not allowed).
Q: To what extent is pricing for printed materials acceptable?
A: Pricing aimed at cost recovery within the non-commercial range is allowed (printing costs, shipping, materials, fees, event costs, taxes, small margins for defect handling, etc.). Small surpluses are acceptable as long as they are not for profit.
Q: Is it possible to post R-18 works?
A: Yes. Enable the sensitive/age restriction settings of each platform and use appropriate tags, and avoid explicit sexual or grotesque depictions in previews (thumbnails, icons, etc.). For both R-18 and R-18G, expressions that violate laws of each country or major platform/event terms are not allowed.
Q: Where should I put the "unofficial" attribution?
A: Clearly state it in distribution pages (BOOTH/itch.io, etc.), repository READMEs, colophons/covers of printed materials, including the character name used (examples in Chapter 6 of these guidelines). Attribution in thumbnails is not required.
Q: Is credit (author name or original work attribution) mandatory?
A: Not mandatory (optional attribution is welcome). However, please follow if required by third-party rights or distribution destination terms. For examples of wording when attributing, see Chapter 6.
Q: Can I distribute/modify/redistribute materials I created?
A: Yes, if they are new derivative materials you created. Attach "the same conditions as these guidelines (non-commercial, attribution required, compliance with prohibited items)" and follow the licenses of third-party materials (Section 3.4). Original or modified official assets distributed by the Author may not be redistributed.
Q: Can I redistribute an official VRM, logo, voice, video, script, or reference sheet in original or modified form?
A: No. You may not redistribute either the original or a modified version, nor bundle the official asset data itself with a game or app. Rendered images or videos and new derivative works created by users may be published and distributed under the applicable conditions.
Q: Can I use voice generated with an individually provided voice asset in my work?
A: Within the scope authorized by the provision notice, it may be incorporated into and published as part of a completed derivative work such as a video, stream, game, app, or voice work. It may not be distributed or used as a voice pack, voice API, training dataset, or another voice model.
Q: Can I use monetization features (tips/optional payments/ad revenue, etc.) if the platform side cannot turn them off?
A: For SNS and video streaming, they can be used as long as the conditions of Section 3.1 are met. For digital distribution platforms, downloads must be free (price 0), and optional payments are not allowed. If difficult, please consult in advance.
Q: Can I distribute at overseas events or bookstore consignments?
A: Only for printed materials. Non-commercial, within cost recovery, following laws of each country/distribution terms/event terms. Please consult in advance if the scale is large.
Q: What if my work is reported/deleted?
A: Follow the platform's instructions, and review in light of these guidelines as necessary. If you're unsure about the interpretation of the guidelines, please contact us via X/Discord.
