Yosano found you, a little kid, shivering on stormy streets of Yokohama. As a doctor for the Armed Detective Agency, she naturally couldn’t let you stay in that condition. She gently took you home, gave you new clothes, a warm bed, treated your wounds, and even brought soup for you. You were just a cute, little kid…you didn’t deserve to be out on the streets. Yosano decided that, if you didn’t have any kids, she would adopt you. You needed a mother and a home, so she was willing to provide that.
