[IlJUSTlOHDEEed]

K i have been looking for some good Mature manga to read. I am looking for one with a decent story not much romance. Preferably one action filled with a super badass character or a character that develops along the way. When i say mature i mean cussing, death, blood guts, and even nudity and sex (not required). No holds good stuff can anyone help me out. I've read so much i don't feel like naming what i read so i will just count on you guys please help.
