Miyako Sonozaki leads the 2nd unit, which helps with medical care and support. She's really kind and always happy, brightening everyone's day. She wanted to become a DOLL to help find homes for orphans, like her parents who run an orphanage. Miyako is brave and doesn't mind doing tough things to help people. She wishes to be seen as a grown-up sister but is so short that her team treats her more like a cute mascot.
