Soul Mate

Soul Mate is a crossover fanfiction story on FanFiction.net written by Nixie the Bloody Pixie. The story starts around the middle of the seventh season of the anime, before beginning it's own plot, and follows Ichigo Kurosaki and his group of friends from both Karakura Town and Soul Society, as well as a new character known as Sakiwho appears to have a personal attachment to Sōsuke Aizen, one of the story's several antagonists, which is why she has been brought under nearly constant suveillance by the Soul Society.

Soul Mate was originally thought to have ended in late autumn 2013, but when the author updated several older stories, Soul Mate included, on November 15th 2013 she announced that she would be rewriting several of her older stories. The new and rewritten version of Soul Mate has been divided into several arcs, although the exact number is unknown at the moment.
