The Double Edged Sword

Banished to the mortal world after serving her grandfather for over 600 years, Izumi Yamamto, clueless as to the reason of her exile, has spent six long years experiencing new possibilities with her friend Ichigo Kurosaki.

They came together by chance the day of her banishment when he was just nine years old.

Two horrible tragedies tied them together; the death of a loved one, and the betrayal of a family.

Together, along with her uncle figure Kisuke Urahara, they have worked to face Izumi's horrible past while she attempts to heal both mentally and physically.
...
Progress had been made, until Rukia Kuchiki arrived shattering the makeshift peace in Karakura Town.

With a relit fire taking hold of her heart, Izumi declares her wish to return to the Soul Society to confront the man she called her grandfather. Little did she know her best friend would be along for the journey.
