Shredders Daughter

(Y/n) Oruku is Shredders actual daughter. With Karai as her half sister. Her mother, Tang Shen, died in a fire when she was a little baby. Karai being younger than her hates (y/n). Shredder loves her and showers her with fatherly love, Karai gets hardly anything.

But one night Karai took it too far...

What happens when (y/n) meets the turtles and falls for a certain blue masked turtle? What will Karai do? And most importantly what will Shredder say to the relationship?
