I remember watching this movie 17 years ago… I don’t where it starts…
The whole plot goes like using someone’s blood ( may be the chosen one or sacred guy) to protest themselves from demons who look like humans and in a fight with demons, the main protagonist dies and asks a girl to take his blood and she collects his blood into a bottle and leaves
And in the ending scene she enters a bus and at the bus door she uses his blood that she collected earlier to draw a line… And later one demon hiding in human form tries to get on bus and sees the line she draw and just smiles at her and walks away…
