This is the one Flower Breathing form name VIZ chooses not to fully translate. "Crimson Hanagoromo" leaves 花衣 standing as a loanword mid-sentence, the same treatment the localization gives 鬼 (oni left as a concept but rendered "demon") or certain honorifics elsewhere in the franchise — an acknowledgment that some words carry more color when left visibly Japanese. It's a notable outlier: every other named Flower Breathing form on this hub gets a complete English gloss ("Honorable Shadow Plum," "Peonies of Futility," "Whirling Peach," "Equinoctial Vermilion Eye"). Only this one keeps a bare Japanese noun sitting inside an otherwise English callout.
The choice makes sense once you know what 花衣 actually names: a real garment, not an invented poetic image. Every other form in this style borrows from botany or Buddhist cosmology to build its name from scratch; 紅花衣 instead borrows a pre-existing word for a floral-print kimono worn specifically for cherry-blossom viewing, and simply tints it crimson. Translating it fully — something like "Crimson Flower-Robe" — would have made a real, still-worn category of clothing sound like a costume invented for the scene. Leaving hanagoromo transliterated does the opposite: it tells an English reader this is a term the culture already had a word for, without over-explaining what that word evokes.
The technique's placement in Kanao's fight is also worth noting for readers following this hub's Flower Breathing set as a whole: Fourth Form appears one volume before Forms Two, Five, and Six, which cluster together in the climactic Volume 18 chain against the same opponent, Doma. VIZ's pagination runs true (no page offset) for this Volume 17 panel — a useful contrast against the +1 offset that affects nearly every other technique in this style's corpus citations, all drawn from the following volume.
