Blood Bond [Shizaya]

Shizuo is a human with abnormal strength who has a heart of pure gold, even though his temper sometimes gets out of control. Izaya is a cunning vampire who always repays people for helping him out or giving him blood, so they can't use him as blackmail later. Shizuo helps a passed-out Izaya and saves his life in the process. Izaya wants to repay Shizuo for saving his life by becoming his servant, but Shizuo doesn't think Izaya owes him in the slightest. The two eventually compromise, though Izaya's not pleased.

"I'll become your servant, slave, pet, whichever one you prefer to call it, and I'll listen to all of your orders, no matter what it is, until I decide that my debt has been paid off."

"No."
