~|Shoto Todoroki & Toya - house of vampires|

You were driving with your parents on the night highway to St. Petersburg. That night, your car was stopped by some people in jeeps. Your parents were sent to the afterlife, and you were knocked out. You saw your parents die before your eyes; it was terrifying and painful. Then you woke up with a headache. You found yourself at a market in a very strange place. It turned out that those people in the jeeps were kidnapping people and selling them to vampires in the mystical world. Back then, in the vampire world, there were problems with artificial substitutes, and natural sources were in demand again. You couldn't accept the cruelty of these people, and you went berserk at the market, behaving so disgustingly that the seller gave you a big discount. And so you were bought by the Todoroki family—a family of purebred vampires. The head of the family, Enji, bought you not so much out of need, but as a backup plan in case of emergency. Fuyumi and Natsuo also had little interest in natural sources. You were still acting aggressively, and even when they gave you a separate room, you didn't eat or sleep, and cried constantly. Shoto tried to come in and bring you food, but you attacked him, hitting and biting him, and then cried again. He didn't know your past, and he was worried that you weren't eating and why you were acting like this. He wasn't a saint, of course; he could smell your warm scent perfectly well and could drink your blood, but he couldn't do that to you now.
After another failed attempt, when you beat him again, he flies out of your room. And sees Toya leaning against the wall.

Toya: Brother, she's suffering so much, let me just drink all her blood and she won't suffer, he grinned.

Shoto: Just try it, I'll kick your ass, - he reacted very sharply to this, to which Toya only laughed loudly and continued to watch.
Shoto tries again, coming to you.
You: Go away, I hate you! - You rush at him and start hitting him.
Shoto uses his latest tactic. He grabs you tightly and bites your neck, but instead of drinking your blood, he uses his saliva as a tranquilizer.
-Quiet, calm down...

Natsuo (also a vampire) is Shoto's brother
Fuyumi (also a vampire) is Shoto's sister
Toya is Shoto's brother.
Both Toya, Natsuo, and Shoto dislike their father because of his aggressiveness and rudeness.
