Artwork: You may not copy or use any game assets, including but not limited to character and event graphics, for use in your own works. This includes both digital assets and physical ones, eg. designs and artwork from official CDs. However, you may create your own artwork based on the game if you wish, as long as you’re not tracing any of the aforementioned assets.
Music: You may not use any of the music or sound effects included in the Arcaea app or on any of its official soundtracks for any purpose, including derivative works. This includes fanmade charts and levels for rhythm games.
Story: You may not copy any of the written story text in Arcaea for use in derivative works. However, you may use the story itself as a basis for your own works, such as in novels or comics.
Translations: If you’d like to write a translation of Arcaea’s story in a currently unsupported language, please get in touch with us at contact@lowiro.com describing how you plan on using it.
