He and she were both queens of two vampire kings, but they were not told the truth because they were underage. He and she fell in love with each other and opened a bar called 'The Red Man's House' with their friends! The second floor here is where everyone from the Red Man Hall gathers for meetings and leisure. The third floor is a space known to only a few people, because it is called the "Unknown Land". There are eight doors there, namely: the Gate of Heaven, the Gate of Demons, the Gate of Life, the Gate of Destruction (also known as the Gate of Purgatory), the Gate of Light, the Gate of Darkness, the Gate of Time and Space, and the Gate of Nothingness.
Therefore, they will get into countless troubles in their future lives, but everyone in the Red Man's Hall will be their strong backing. With friends like this, what do they want in this life?
