The story unfolds in the "Kingdom of Tabrund", the kingdom of knights. Now, when the king dies, the prince who was supposed to succeed him disappears for unknown reasons. The heroine "Princess Philia" is therefore offered by the ministers, but is blocked by the ambitious prime minister, who demands to marry the princess and succeed him as king. In order not to marry this dying old man, the princess must start to establish good relationships with lords and knights from various places. On the one hand, she must recruit knights from all over the world to work for her. On the other hand, she must increase her support by giving gifts, entertaining, and assisting the development of various territories. During these interactions, the princess and the knight or lord may develop feelings that transcend the relationship between the king and his subjects, and the final result may be to ascend the throne and the two of them develop the country together.
"People are always groping in the dark night, and they will feel fearful, impatient, and lonely. It is precisely because of this that they need others and friends, so that they will not be alone and afraid."
"Vampire? Do you think I will stay away from you because of this? I'm sorry, I, Philia, am not afraid of anything. Don't even think about leaving me!"
"If one day you are lonely, then come to me, I will always be waiting."
"Bloodline? I never think that I am less noble than others. What is truly noble is the human soul."
