There are a bunch of yukkuri who often says something that is unique to them.
I thought of listing them for reference, and maybe discover some more if you guys know any.
"ze" is Kirisame's catchphrase too.
For the most part, she's lost in translation.
Reimu almost always end her sentences with "da yo", and some artists have played on this by making her say it like Marisa's "ze".
Something like "かわいくて ごめん ね！ だよ！" (sorry for being so cute! da yo!).
The problem is that "da yo" often is actually part of the sentence ("da" is a verb), so it can't be written as-is but has to be translated
She's very city-sect. Definitely not a country bumpkin.
Also "nhoooo" I guess.
She gets it.
YoumuEven the actual half-ghost gardener goes "myon" in pretty much every fanwork.
The yukkuri goes "dick!" too.
PatchouliI wonder what ZUN was thinking when he made Patchy go "mukyu" after you beat her.
RumiaIs that so?
Aya/KimeemaruOhh, catchphrase, catchphrase.
SanaeThe japanese language has different words depending on how polite/humble/formal you have to be, and Sanae usually uses very polite words, compared to other yukkuri, so I believe we can consider this her "catchphrase".
Remilia & FlandreU~ u~ u~!
Also Remilia goes "dado".
NazrinShe ends her sentences with "nazu", which if I'm not mistaken was translated as "~mouse" in english.
SakuyaShe often calls for "ojou-sama".
Lily WhiteThe fairy can only say "pyuyuyuyuyu" and "it's spring", so I don't see why people would remove her purpose (announcing spring) just because it's a yukkuri.
YukariYukarin is 16 years old!
CirnoEye'm the strongest!
YuyukoShe goes "little bones" if I'm not mistaken.
ParseeThe paru always go paruparuparu.
