-Yui was something of a spoiled, isolated child. As the only heir of the vampire king, she was treasured, and with no siblings for competition, she never had to deal with fighting for her place at the throne. She lived a relatively spoiled childhood, well protected by her father as his only heir. Her mother died when she was young, supposedly, and she was always close to her father.
-However, a protected childhood, for a vampire, means an isolated one. Yui was kept well away from any potential dangers, which meant that she was alone for most of her youth. Her father was always busy with his own things, and Yui was left alone to entertain herself with servants and human playthings from a young age. She was loved, but sadly rather neglected.
-The boys are not the first humans Yui has been offered. Over her supernaturally long lifetime, her father, other vampire nobles, and friends have sent her all kinds of human as “gifts” to feed on and toy with. Most of those playthings have met some kind of unfortunate end, either through another vampire’s doing or her father’s whims when he gets bored of them.
