From Mami & Rika's Dual Legend article:
真琴: 音楽学校時代は眠い印象しかなくって、起きてなかっただけなのよ。
[Mami was famous for sleeping a lot, she even managed to fall asleep during ballet class...]

Picture: It was Mami's first oversea trip. Destination: Hawaii. She associated Hawaii with blazing sun and roaring sea. But when she got there, she was drenched in heavy rain. In only one night, during the rainy season, her image of Hawaii as the eternal summer paradise collapsed. It was so cold that "even the beach was purple." LOL. Back at the airport, she was tired, of course.
