Ring 0 : Birthday
Ring 0 is the Japanese prequel to the Ring Mythos.
Where Sadako Yamamura is early in her college experience, and dealing with the typical issues of trying to succeed in her love for theatre, and her romantic life. She is cursed, and is generally unaware when this seemingly multiple personality takes over her being, in this Shakespearean tragedy of a film that leaves one wishing it could have ended differently.
Truly a masterpiece which inspired me to submit a sort of comical comic strip parody to a Ring 0 art contest last year, where I won third place, which was pretty exciting. You can see the finished comic on the website's media page.
