Don't even think it's anywhere close to Bleach.

Soul Girl is completely original and it is my plotline. Anyway it is a plot for a manga I wanna create. It's about a guy who lives in Tokyo who suddenly gets caught in the cross-fire of a female Grim Reaper trying to kill a Bad Soul. Before you say anything, Bad Souls DO NOT have white masks; they are pure evil and cannot be cleansed and MUST BE KILLED. Nor, do Grim Reapers have the ability to cleanse said souls in the first place. Anyway, moving along; Sato, the guy ends up getting hurt in the cross-fire, thus making Lilica, the female Grim Reaper have to bind her Chain of Binding to Sato's soul in order to save it from being devoured by the Bad Soul she had been hunting. Needless to say, Sato ends up having to bring her to his dorm room. Lilica takes on the guise as a college student to be with Sato. This ends up being a story with a lot of fan-service. Anyway, the story goes; someone is summoning all kinds of powerful Bad Souls, and is basically warping Earth's Spiritual Equillibrium by bringing more Bad Souls. Thusly, the world's leaders begin to become corrupt. Basically, Bad Souls not only destroy things and devour souls, they can cause moral deprivation as well. After hunting a few Negative and Bad Souls together, Lilica and Sato encounter more Grim Reapers, like teh chainsaw wielding lolita girl, Lolika who is actually Lilica's sister. This is pretty much the plotline. I'll have more details later...*WHEW* Damn that was a long breifing.
