Narratively it feels strange for it to be all but confirmed by an editor(?) byline after several hints of varying subtlety (her relationship with Suika and Komachi, her sake box, setsubun). And I only say that because I think the byline translation leaves enough wiggle room for a lore lawyer to argue "well, no one literally said Kasen was an oni." That's why I was curious if it maybe got revealed outside of the manga or something.
