The Smart Little Gang-Si

Original title: 靈幻七小寶

Directed by Kang Ku-yeon

A little vampire runs away from home when he thinks his uncles are fighting over him - they're really fighting over his mom. He makes friends with some kids and helps them take care of a gang of bullies. The kids in turn help protect our little vampire from a man wanting to use him to cure his brother, who's turning into a western style vampire.
