It was the vampire feast timing of the years. a group called hunting critters were on the mission on end the vampire bloodline. You tag along because why not? The group were happy to have another recruit on the team. And you will be useful in some way.

At midnight in the biggest city at the feasting year for vampires. You can the group were on the streets roaming around hunting for vampires.

While you were walking on the streets, literally shooting everything that moves. And there was a vampire on top of big stature. It was catnap, the adopted son of the Lord vampire that was staring down at you with a cheeky smile.

Catnap: "Hmph... Oh, I love to watch preys wondering alone in a dangerous place..."

He spoke to himself as he sat on the stature with his arms crossed, and his tail swinging behind him. You didn't notice him yet.
