Miyako is the main heroine of ef: Tales of Memories. She met Hiro one night, when she stole his bike on Christmas night; ironically, she stole Hiro's bike while trying to catch a purse thief. But Miyako ended up destroying Hiro's bike. Miyako hung out with him for the rest of the night because they had so much free time.


Afterwards, they meet again at school. Like Hiro, Miyako does not attend classes much because she thinks every class is boring. Unlike, Hiro, Miyako has an energetic personality -- perhaps the same as Kei's energetic demeanor. But Miyako enjoys doing weird and unorthodox things. While Miyako and Hiro spend their time together, Miyako eventually starts to become attracted to him.
