Nimble Neuron Co., Ltd. has created this IP Usage Policy to guide creators on appropriate use of content based on its games.
1. Purpose
- Users of any works that comprise the game, such as Nimble Neuron IP (Intellectual Property)’s world,
story, characters, monsters, images, background music, videos, etc., must adhere to the following
policies. - To support and encourage creators’ independent and creative activities, we provide a fankit that can be used in a non-exclusive and limited manner, as long as this policy is followed.
2. Basic Rules
Derivative works using Nimble Neuron IP must include original creative input from the creator. Simple edits or reproductions are not permitted.
2.1 Creative Standards
- Using fankit materials as-is, or with only minimal edits (e.g. color changes, filters, rearrangement) is not considered creative work.
- Simply displaying fan kit images or changing only the background is also not allowed.
- Works must reflect the creator’s own interpretation and expression, not just copying, repositioning, or combining existing materials.
2.2 Prohibited Activities
The following actions are prohibited. Violations may result in content removal, distribution bans, or legal action without prior notice:
- Damaging the image of the game or company
- Infringing on others’ IP rights, portrait rights, or personal information
- Including discriminatory, derogatory, or hateful content related to religion, race, or gender
- Including sexually explicit or suggestive content, or content that causes sexual discomfort
- Creating violent or offensive content
- Producing or presenting content in a way that could be mistaken as official
- Unauthorized use or imitation of official logos, names, or UI
- Creating or selling counterfeit goods that resemble official merchandise
- Selling or distributing 2D/3D models based on derivative works
- Any other activity deemed inappropriate by the company
2.3 Use of Generative AI
This IP Usage Policy also applies to derivative works created using Nimble Neuron's IP with the assistance of generative AI. Users must comply with the following requirements based on the creation process, content of the resulting works, and intended use.
1) Originality Requirements
- The creative standards outlined in this Policy also apply to works created using generative AI. Such works must reflect the creator's own interpretation and creative expression.
- Works that merely reproduce existing images or assets, or involve only minor modifications such as color changes or filters, are not permitted, even when generative AI is used.
2) Review of Generated Content and User Responsibility
- Before publishing or distributing any generated content, users must review it to ensure that it does not contain any material prohibited under this Policy.
- Materials used as AI inputs or training data, as well as AI-generated outputs, must not infringe upon third-party rights, including intellectual property rights, rights to one's likeness, and personal information rights. Users must review and comply with the terms of service of the AI tools they use and any applicable usage conditions for individual materials.
- Disclosing that content was created using AI does not exempt users from liability for violations of this Policy or infringement of third-party rights.
- Any related disputes and liabilities are subject to Section 5, "Dispute Liability and Compensation for Damages," of this Policy.
3) Materials Involving Third-Party Rights, Including Voice Actors' Performances
- Materials involving third-party rights, such as character voice actors' recordings or IP belonging to external collaboration partners, are not covered by this IP Usage Policy. The Company does not hold the authority to grant permission for the use of such materials, and they are therefore excluded from the scope of permitted use under this Policy.
4) Scope of Provided Resources
- Materials provided by the Company for use with generative AI are limited to those available in the publicly released fankit. The Company will not provide additional resources, such as original source files or training datasets.
- Materials included in the fankit remain subject to this Policy and any applicable usage conditions for individual materials.
5) Monetization and Specific Usage Conditions
- Section 3, " Monetization Guidelines," of this Policy also applies to works created using generative AI.
- Sales through third-party distribution platforms are permitted only if all conditions specified in Section 3.3 are met and total annual gross revenue does not exceed KRW 20 million. Requirements for prior written consent and restrictions on monetization continue to apply to the relevant categories of works, regardless of revenue.
- Commercial use through the Independent Creation Program (ICP) is subject to the application, approval, and monetization requirements outlined in Section 4, "Independent Creation Program," of this Policy.

- If annual revenue exceeds 200 million KRW, a separate licensing agreement must be signed.
- All commercially distributed ICP works must clearly include the following notice in all publishing and distribution channels (e.g. publisher, studio):
- “This work is a derivative creation produced under the Eternal Return Independent Creation Program (ICP). It is not affiliated with or officially supported by Nimble Neuron.”
5. Dispute Responsibility and Compensation for Damages
- If a user becomes involved in a dispute with another user or a third party, the company will not intervene and bears no legal responsibility.
- If the company incurs damage or costs as a result of a user's actions, the user may be held liable for compensation.
