My battle with her to determine the true idol was left unfinished during the prefectural qualifiers!
معركتي معها لتحديد النّجمة الحقيقيّة لم تُحسَم
خلال التصفيات الإقليميّة
¡Mi lucha por ver quién es la verdadera
idol no terminó en las clasificatorias!
Ma bataille contre elle
Durante i prefetturali, la nostra battaglia per 
il titolo di idol del mahjong non si è conclusa.
Ainda não decidimos de vez qual de nós
duas é a verdadeira estrela do jogo!
