Usually FanFics and stories have one OC added in. But what if there were two? Two best friends in New York; one born Yokai, one born Human. One, having a hard family-life, escapes their home. Unaware of the danger lurking by. The other, having a wonderful life living with four brothers in the sewer, decides to take them in. What adventures might these two go on? Will the humanity find their child again? Or will they stay safe with the turtles and their friend?
