Tomie is not a bad manga, however, it is flawed with the biggest one of it being repetitive and almost nonsensical. The story centres around one beautiful girl named, well, Tomie, who takes a mean grip of mens' hearts and subverts them to do any and every of her beckoning. The men, as if under some sort of a trance, are more then willing to kill, beat, threaten and berate any one on whom Tomie points her well manicured accusing finger at.
The manga is made a compilation of stories (for most parts one-shot style) featuring Tomie as the antagonist, with the unfortunate protagonist (most often male) serving as her object of affection and the device that shall eventually put an end to her life.
By the end of nearly each chapter Tomie is slashed to pieces only to be miraculously reanimated in the next one.
Perhaps based on a folklore or an urban legend, Tomie does deserve your attention as it has pretty gory stuff in it, but hardly three volumes of attention...
