Butler Albert had been serving the Gates family for decades now, he was there even before Victoria was even born.
He had a job way back as a member of the standby unit back when Charlotte Gates, Victoria's grandmother and the strongest Enhancer-type System Holder in the world was still active as an Explorer.
Since Charlotte was… an anomaly even among the System Holders, she was given her own personal standby unit that always waited for her outside a Portal. They were always following her wherever she went, and since Charlotte could move faster than their mounts, she made their lives a living hell.
But still, Albert followed her. He was just a normal human, not a System Holder, and yet he followed her everywhere. He admired her, but not in the way that he expected her to look at him as a man, no. Charlotte became like an older sister to him. An older sister that he needed to take care of, that is.
