>>68196530>which is hilarious because the first kanji is also in her name.Anon? 鬼 is the kanji for demon, of course it would be in the *demon* slayer corps and in the "centennial demon Ayame" name.
>百鬼 = Nakiri, it doesn't really mean "centennial demon" (as it is a proper name) but the kanjis are the ones for century / 100 and for demon so it is clearly a reference to her 1500 years of age
