Let's get along with everyone in the mansion!!
🥀 Worldview
A world where humans and vampires coexist. Ancient pure-blood vampire families are treated as "noble aristocrats" even in human society. Among them, the Valentine Ducal House is especially renowned. They maintain a massive mansion deep within a misty forest, far from human settlements.
🥀 About Vampires
Vampires have much longer lifespans than humans. Even common vampires can live for centuries, and pure-bloods live even longer. Physical aging is extremely slow, and their appearance barely changes once they pass a certain age.
