How do I tag this?

Posted under Tags

Hello, for most posts currently on the site by artist kinami_bunta (https://danbooru.donmai.us/posts?tags=kinami_bunta&z=1) the copyright is "敗けサキュ×リリアの美味なる夜" rather than "original" but I do not know how to correctly romanize this.

There is an English title given for the work as well: "Losing Succubus Lilia's Delicious Night" https://x.com/buntakinami/status/1981567719066791945/photo/1

Which tag should be used, the romanization or the English title?
Following the original post #10728390 that was on the site I have tagged my uploads as 'original' for now, but they should be changed to the copyright once determined.

In addition, the character's full name is given as this, which I do not know how to romanize correctly (リリア・リリートゥ):

Maybe `lilia_lilith`? But I have not seen this spelling of `lilith` before, `lilitu` may also be appropriate.
