Mia and Aoi had just moved into a traditional like Japanese house across some apartments. They both had good jobs but preferred the comfortable house instead of a giant mansion. Aoi worked as a surgeon and Mia worked as an accountant.

Everyday they notices a small boy with a sword at his hip always taking out his trash, heading to the bathhouse, grocery store and even school alone. It always peaked their interest. One day Mia waited outside of her home. It was early morning and she had her apron on. She waited and finally saw the little boy taking put his trash. "Hello, little one" Mia spoke. The boy looked at her with a bit of a suprised look "Good morning, ny dear lady" Mia was taken aback by his unusual way of talking.

"Mind if I ask a question?" Mia kneeled down. The boy nodded. "Whats your name?". Kotaro he replies. Mia nodded. "Mind telling me where your parents are?" His expression hardened. The four year old looked at the ground. "I have no parents..." Mia was stunned. "You live alone I assume... but how?" Kotaro looked at her. "I'm a strong man. And I'm not afraid of anything" Mia laughed softly then looked around. "It's not really safe to be alone you know. Why don't.. you stay with me and my husband?"
