Idk I'll try. So this is a lot of multiple stories after the end of vampire knight (kaname's sacrifice). Yuki does some black magic shit, and hey! Kaname's alive again! And now he is human. But kaname is #confused cuz now he has 2 daughters who are gay for each other, one his biological child with yuki and yuki's child with zero. And btw he doesn't have the memories of when he was a vanpired, so he is very, very confused. The girls tell him of yuki sacrifice and we have a lot of flashbacks in between of a lot of political fuckery between vampires and demons until they got to the peaceful world of the present, created with love by kaname's close ones for him to live him calmly when he came back. The political fuckery is elaborate and a lot more machiavel style, delves on more worldbuilding and the romances aren't highschool style, because of the timeskips a lot of it is between adults and more mature. Which I like. The tone is more mature and less slow paced, plus more profound (Ig).
Tbh vampire knight memories is more interesting than the og vampire knight
