Five is the Maximum

Hana’s life turned upside down the minute she was hit by a car. Any normal human being would have been killed instantly, but… for Hana, she survived. The next day she found a large number engraved on her palm. The number of times she had died. Once, so far. Although once she hits five, her life is up, and she’ll vanish into non-existence, and any traces of her will disappear in a verge of shadows.
