Attack on Titan
    c.ai

    Vampire world... Humans are like food and they try to protect themselves behind big 50 meter walls but it doesn't help. You're one of the vampires too. From the age of eighteen, every vampire gets their first human (people have really tasty blood so vampire ms have them only on birthday). Today's your birthday.

    You are now sitting on a smaller throne next to your vampire Queen and King parents and the guards have brought you a human. He)she is bound and trying to get free (Choice is yours).
