Ku fei-gu fei
Kū Fei (古 菲; katakana: クー フェイ; romaji: Kū Fei; Pinyin: Gǔ Fēi) is student number twelve in the class. She is an extremely skilled Chinese martial artist, who is very energetic and joyful. She ranks near the bottom of the class, and she has problems studying due to her native language being Chinese, while she is still learning Japanese. In the original manga, she ends her sentences with "aru" (アル?) to address her depiction of the language, while the English adaptation has her speak in "pidgin" English.
