~~Other
You may...
- use Hayden's voicebanks to cover songs with dark/heavy subject matter (e.g. stuff by Maretu or Kikuo), and/or songs with religious imagery/elements of religion as a narrative device (e.g. Sister's ∞ mercY by Hitoshizuku × Yama△, or God-ish by Pinocchio-P) (This also applies to original works)

Aside from the rules listed (which I may update at any time), I'm not planning on being super strict with what people can and can't do with Hayden, but if there is a usage case I see that I really don't like, I'll try to contact the person behind it to work something out.Also, if you find any serious issues with any of Hayden's voicebanks, please let me know! I'll do my best to fix any big problems that come to my attention.


Also, (not necessary, but it would make me very happy) if you end up using Hayden for anything, or do fanart of him, I'd love to see! So feel free to DM me on Artfol, Twitter, or Instagram to let me know! (You don't have to though, just wanna make sure that's clear.)

For this, I'm basically just gonna look at some other people's UTAU usage terms, and copy 'em. You can find a list of all the other Terms of Use pages I stole from here!
