(this is the same as what I've posted on PixilArt and BlueSky)
I read through Larvie & Libro (larvieandlibro.neocities.org/…) ‘till I got up to date recently, and I have some headcanons for them both, at least I think they’re headcanons; the comic itself has a few key panels that hint to Larvie and Libro being not cis, but I don’t know for sure if that’s just the spontaneity of the writing or something else. Excalibur Twist on the other hand is described in their character bio with they/them pronouns, so they’re probably non-binary but that’s not confirmed either; the whole comic is a shitpost, so it’s hard to know what’s canon and what isn’t unless the main creator herself confirms it, like in Chapter 7, “My Freaking Magnum Opus”

Just read the comic it’s great, what I’ve rambled about isn’t relevant: https://larvieandlibro.neocities.org/
