The heroine accidentally traveled to the world of vampire knights and became Takuma Ichijo's sister. Absolutely no life experience. Just an ordinary noble vampire. Yes, this is a time-travel article, but the heroine is only a witness to everything that happens here. Because the author supports Shuji, if the children of Lingji don't like it, don't tell me! The last thing I want to say is that the main plot is still the original animation plot, with a little bit of Lan Tangying added.
