A vampire school girl who is sometimes strong and sometimes weak X a reliable and powerful daughter student council president
"I fell in love with you before I tasted the warm and sweet blood."
Today, more than a thousand years after the "Instrument Revolution" took place, magic-driven steel locomotives race through the streets, supporting tall buildings and towers to climb higher and higher into the sky. They are introduced into thousands of households to run furniture to benefit all living beings, but they also bring curses to innocent unfortunates.
"Just like people need to eat and drink, I can't survive without ingesting the blood of my fellow humans."
"Since the act of sucking blood is necessary for you, I will do it."
The unfortunate but lucky girl tried hard to climb out of the trough of life. The lucky but unfortunate girl was given a new lease of life in the blink of an eye...
The girls are locked in love and embark on the road to tomorrow hand in hand.
Concept: The love between girls is flawless. Human character is rarely pure, but it still shines brightly.
