This story is about two sisters who lived in North Korea in a city called p'yongyang.

Yoona happens to be the oldest who lives with her younger sister Seohyun. Yoona was 19 and Seohyun was 15. Their parents did not live with because of  the way they treat Yoona and Seohyun they both ran away from home at the age 11 and 15. Yoona loved Seohyun very much but, Yoona is really half human and half nine tailed fox. The first person that Yoona loves dearly and would die for that person (even though she is completely invincible and won't look any older untill she looks like she's 23) that person will become a nine tailed fox with nine tailed fox powers (strength, flying, super speed, one fox orb that will rise people from the dead) and invincibility. Yoona will tell Seohyun when she is 16 which is in 2 more months because Seohyun's transformation will begin. What will happen here is their story.
