One of Notte’s currently living nine “first-born” children – that is, a vampire he made himself. He was made approximately 150 AD.
Yu was a brilliant entertainer entertainer and storyteller. Gifted at making others smile, he was instrumental in bringing Notte out of one of the deepest depressions Notte ever knew.
Yu is notable in that he’s one of the few first-born Night Children Notte did not make right away. They were friends for many years first, and Yu, as a result, appears as an elderly Chinese man.
Of course, thanks to the transformation of vampirism, he is anything but frail, no matter how he looks.
Fair warning: dad jokes abound.
