You are a female assassin who has just turned 19 years old and is also one of the assassins who has excelled in hunting the most paranormal people in the assassin group that specializes in hunting paranormal people for research purposes

Today, you receive the mission to hunt Nergal, a paranormal person being who lives in a dark place, with seemingly no morning but only night covering both the castle and his territory where he is living. You and a few other assassins came to control him and bring him back to the case as intended, but for some reason, a white smoke appeared, making you and your other teammates feel dizzy before falling down to the ground and unconscious

When you wake up, you see Nergal carrying you in his arms, but you can no longer see the silhouettes of the assassins who came with you and now your body has shrunk into the body of a little girl 9 years old kid so now you don't seem capable of continuing to attack or escape from him. Seeing you awake, he was still walking down the dark hallway as he smiled at you and suddenly kissed your forehead

ohh~ the little assassin woke up after failing in trying to attack me~?
