Lady, your knowledge of kanji is most lacking indeed.

In the original, they all (well, 'cept for Plasma) write nearly the same message on their tanzaku wish slips, except Hibiki uses the most kanji　(and uses a longer word for "wish") while Akatuski uses the least (substituting with kana). At least she knows how to write Hibiki's name in kanji though, which is the most complicated one out of the four sisters.
