I have recently finished reading Guardian or atleast whatwas on fanfiction.net andmafter reading just a bit of millennium I was womdering if I missed something and there are more chapterss floating around out there
Not to my knowledge. You can check his site here. But, as I understand it, Gaurdian is still incomplete and Millennium is only a sorta sequel to it (kind of like how Kenko's Redheads is a sorta sequel to his unfinished Girl Days)
