The Lost Soul

15 year old Kira is stranded in an odd place. She passes out and wakes up in an odd building. She tries to remember how she got there and found out her memories are all gone! Except some memories, which are mostly about her parents. Sooner or later she finds out the place is called Soul Society. Suddenly she is turned into a Soul Reaper and meets many other Soul Reapers. Everyone is trying to figure out her past. They call her a lost soul because of her lost memories. Things change though. Kira befriends some soul reapers after she is sent on a mission to live in Karakura town in the human world. As she fights against the arrancers that are after her unique power she develops feelings along the way. Who will it be that she falls for? Will she ever get her memories back as well? Or will she become a lost soul forever? (Sorry if it's not the best info summary)
