When Asian vampires steal an ancient demon?s mask, a museum curator team with a manga expert to stop them from bringing the monster back to life

Quality in stories is about the coherence and relation between all the parts. In this logline we are not able to appreciate the relation between the character of the bus driver and the asian vampires. I try to explain... if you said:
"When Nazi vampires steal an ancient demon?s mask, a museum curator and a bathroom cleaner must stop them from bringing the monster back to life". It's the same! It's the same story. I have absolutely no arguments to tell which one is the better. And I can come up with a thousand variation without any peculiar interest. You should do this exercise, and after a lot of work you can find the magic combination between story and character.
Good luck!
