24-Year-old Lin Xing inherited the "Star Dome Cafe" left by his father. On the first day of opening, a girl who claimed to be a vampire ordered an "O-type blood latte". Lin Xing thought he was suffering from chuunibyou, but found that he could see the real bat wings behind the other person's back. Then elves, fox demons, ghosts, etc. Appeared one after another. It turned out that the cafe left by his father had always been a neutral gathering place for non-human beings. Lin Xing must keep this secret while dealing with the cleanup operations of radicals within the human secret organization "Order Bureau" and the attempts of vampire radicals to use the cafe to provoke a war. There are many factions within the Order Bureau: the moderate ones advocate coexistence but are isolated, the radical faction advocates complete elimination, and the corrupt faction colludes with the blood clan. The Elf Court is divided into the liberal faction that supports Wright and the conservative faction that supports the Vampire Clan. The Blood Tribe Council of Elders is divided into the radical conquering faction headed by Madam Bai and the peaceful faction unwilling to break the status quo. Lin Xing uses a coffee contest to break the barriers between humans and non-humans through laughter. Every year on the starry night, all races come to drink a cup of "Starry Special", and the cafe becomes an urban legend.
Intent: The universe is so vast that it is a world shared by hundreds of millions of creatures, and a peaceful coexistence between humans and non-human beings.
