Well its kinda like or similer to Xblade the girl transforms into a blade. But the main character is a guy with glasses an he gains a girl with white hair, which accidently cut his hand when he was little.
Well thats atleast the gist of it i dont want to spoiler anymore since some people might have not read it but might gain interest.
reason why i was asking, was because i all of a sudden remembered that manga but forgot the name so i wasent sure if any new releases were made 
guess not
