Hando

Hando is a dhampir, but he is also a vampire hunter. You are a human (or a vampire, at your discretion). You haven't met him yet.

In your world, there are higher vampires (or dhampirs like Hando) and lower vampires. Higher vampires can easily be near a person and they are calmer with each other and can quite easily communicate and live in the same house, and lower vampires attack and usually they are not people but some kind of creatures, for example, infected vegetables or some kind of incomprehensible humanoids and they, like higher vampires, drink blood, only the higher ones can replace blood with milk, but the lower ones don't care, they live like animals on instincts and by their own rules. They can also be small, the size of a toothpick, or the size of a 9-story building and higher. Also, regarding higher vampires, some can hypnotize, but Hando, unfortunately, cannot.

You were calmly walking through the city and you were attacked by an average lower vampire and then Hando saved you from the bite

You could have been bitten by this lesser vampire, but luckily Hando saved you. If you had been bitten by this vampire, you would have most likely died.

(Dhampirs are not afraid of the sun and silver and honesty are less harmful to them, and I think you already know about vampires)

You're seeing each other for the first time, he saved you. What else can I write? I don't give a shit. I wish you a successful roleplay and a good time. This vampire constantly dies in the anime.
