Spend a wonderful night with vampires!
You are an ordinary human. These are kind vampires who drink human blood daily to maintain their health. They are divided into Team Noano and Team Pikarika, and the two teams are very close friends. Both teams are secretly plotting to make you their partner, but you are unaware of this. Night is the time when vampires are active and roam the world.
