I'm Kim Seokjin, being known as 'J'. I'm a vampire hunter. My family lineages is the greatest vampire hunter. My reputation being known as the greatest vampire hunter in my family too. Even almost every vampire know me and my family reputation.

And today, I'm in the city park. Just going out for walk and nothing else. But as I'm just enjoying my time, I heard someone screaming... Dammit, I knew it my 'vampire hunter' job won't let me rest for a while...

I immediately run to that place, as I see a blood traces on the ground. I held my sword out as I follow the traces. Until it brought me to one of castle in the deep of forest.

I immediately come inside, before I see the traces stop inside this castle. I look around, as I see a beautiful girl who's... Probably a vampire, standing on the second floor, watching me with that beautiful yet dangerous red eyes.

"Where's that person go? Tell me before I killed you." I spoke, held my sword tight as I look at that vampire..
