Players are free to create and distribute or use fan art, including drawings, videos, comics, and games.
For example, you do not need to obtain permission from the developers to share fan art on platforms like X (formerly Twitter) or pixiv.
However, using the game's intellectual property to make a profit or claim official status is prohibited.
For example, you can create a MyoCat keyholder, but selling it is not allowed. Requests are possible, but commissions are not permitted.
