千与少女
[qiān yŭ shăo nǚ]
Translated from Chinese, '千与少女' is 'Sen and The Maiden'. It might be a reference to the famous Japanese film 'Spirited Away', where Chihiro changes her name to Sen. This might mean the holder is fond of the movie or admires certain characters of the story and wishes to represent the spirit of Chihiro who bravely goes through her journey to become an adult.
