@Raey houseki no kuni vibes, alas El is delicate as an orchid, fair as a cherry blossom, the personification of feminine grace and also... a dude. Tall as a willow, slender as a reed, a dude. Radiant in robe vestments, dude. The sun dips low in a rosy sky, secateurs buzz, El is a dude.
@Macamar they're basically genderless though. And by appearence and personality i think ifrit can be considered as a woman while trowell and el as a man. As for the white one, idk
tbh, the author is too "in-depth" in the stories' lore that, just 1 text bubble is like reading 1-5 pages worth of text from a manga, there are too many texts that my eyes just roll over all of them...
