Porn Game: Trouble@Vampire! ~Ano Ko wa Ore no Goshujinsama~ by Tactics-Luxury

Ritsu is a new teacher at a prestigious women's academy,
where ladies from the most influential families of Japan are gathered.
He once saved the lives of his students by protecting them from some kind of magic,
but, having received a serious wound, he died on the floor. When he came to his senses
I saw a girl named Zion, who was actually a vampire.
She called the hero her eternal servant, because. she had to bite him,
to save a life due to a large loss of blood, along the way making the hero immortal.
Sion and her friends had plans to "rule the whole world"
but the hero, without losing his temper because of the situation,
decided to fill their hearts with kindness...and love.
