Kiyosumi High School mahjong members are instructed by the captain of the club to bring their swimwear for a special training session at the Sportsland Pool.  Nodoka and Saki show off how beautiful they are in their swimsuits, attracting people and attention from all directions...
I think it's crucial that everyone be able to sleep on nice, clean sheets for the training camp to be a success.
أرى أنّنا إذا أردناه معسكراً تدريبياً ناجحاً فمن المهمّ
أن ينام الجميع على شراشف نظيفة وناعمة
Es crucial que todas duerman con sabanas limpias 
para que el campamento de entrenamiento sea un éxito.
E per il suo successo è essenziale che tutte siano
 in grado di dormire bene, su lenzuola morbide e pulite.
