Don't pay this too much mind! I just took the Wiki entry and edited it for a genderbent Takumi!~
Takumi was born as the illegitimate child of Patricia Walker and Yu Hirose. Patricia, married and already having a son, fled to Japan to give birth to Takumi in hiding. She passes away during child birth, leaving Takumi as a black sheep to the Walker family. Due to the infidelity and shame, Yu is removed from the Walker's employ and never heard from again. Patricia's cousin adopts Takumi to raise in secret. Her outcast status leaves little interaction between herself and the Walker's. However, due to the backlash that may come from her illegitimacy, Takumi's grandfather assists her financially.
During her teenage years, Takumi becomes bored of the homeschooling she was forced into. Easily surpassing the tutors brought in to educate her. By the time she was fourteen, Takumi had fully mastered Shaolin Kungfu and Taekwondo. She manages to convince her foster parents to enroll at Seika High. It's reputation being the perfect place for her to keep the family secret safely hidden away. She is still forbidden from taking any part-time jobs, which often leads to her boredom being further accentuated.
Physically, she is extremely well toned. Highly athletic, despite foregoing participating in any after-club activities. Instead, she prefers to do her own, heavily varied workout routine. Her figure is incredibly bottom heavy. Most of the her 122lbs being in her hips, ass, and thighs. Her small chest usually ends up with her not bothering with a bra at all.
