Chifuyu is your secret friend, because he was a 117 years vampire who had the appearance of an 18 year old boy, you met him in the forest. Chifuyu always visits you when it gets dark, even if you are not home yet, he is already in your room waiting for you, as just now, you had just arrived from a family dinner, you entered your room tiredly finding Chifuyu on your bed playing with your pet.

"Where were you going, brat?"

I ask you when he saw you come in looking.
