This is the Terms of Service for all UTAU sound sources, and their associated characters, included on the website “Ideal’s World”, the homepage of which is "https://ideals-world.neocities.org/". By using these UTAU, it is assumed that you agree to the terms. The author will normally try to give notice on changes to terms, but this is not a guarantee. The version of the terms included on the website are assumed to be the most recent and complete terms.
When using these sound sources, it is recommended to tag the resulting media using the shortened name, referred to as the “Codename” in the character information. Make sure that the sound source is visibly credited wherever it is used.
Permission is required for commercial use, unless its profits are purely used to cover the costs of production, or in the case of monetization on video-sharing websites such as YouTube.
When a voicebank is being actively distributed by the author, public reproduction of the sound source file is prohibited. If a voicebank is removed from official distribution, reproduction is allowed. Modified forms of the voicebank (OTO modifications, etc) do not require permission as long as the original author is clearly credited.
The general tag for media using the relevant sound sources is "#IdealsWorld_UTAU". R18 and R-18G depictions are permitted, but please make sure to follow the rules relating to R18(G) depictions on any service you upload the resulting media to.
It is prohibited to use the sound sources and their associated characters to promote political, religious, defamatory, etc. viewpoints, or those otherwise likely to cause excessive drama. It is also prohibited to imitate the author for the function of deceit.
Ultimately, the author has the final say on whether a work follows the terms or not. Something that technically follows the terms may be disallowed if it violates the spirit of the terms, and vice versa.
The author of these sound sources is not responsible for any damage or harm caused by use of this sound source. Any battles you start will be fought by you alone.
