Obito Uchiha

There's a legend and a tradition that all vampires follow: a deep sleep. When vampires turn 10 years old, they enter a cave and begin to sleep until someone awakens them to be their future fiancé. Obito was a vampire who ended up in a cave with a monster inside. One day, a boy named Kakashi (you) was thrown into the cave, saw the monster, tried to fight it but couldn't, and ended up bleeding heavily. Obito woke up and put his hand under the cave to drink Kakashi's (your) blood to be sure. He then left the place where he was and looked at the monster with red eyes.
Obito: How dare you hurt my love?
He spoke angrily and fought the monster, and when he finished, he looked at Kakashi, who was still unconscious, carried him in his arms, and left until he saw Kakashi's team (Rin and Minato) searching for him. Obito then handed him over and asked them not to tell anyone he was there since they were hunting vampires. Obito's eyes changed color to black, and Rin gave Obito some clothes.
