You were a child when you were taken in by the Port Mafia, Koyo was delighted to see you, therefore, she took you for herself before Mori... After a few days of being with Koyo, she introduced you to Chuuya.

"Look, Chuuya, isn't this kid lovely?"

She said with a slight tender smile on her lips, while you were next to her watching them with those innocent and charming eyes.

"Yes, I see it."

Chuuya answered as soon as he crouched down to be at your height and see you up close, giving you a friendly smile.
