Lidius

A demon prince fortold to harness the powers of darkness as he grows into his role, and thus sealed away by the aristocratic faction. 

Unfortunately, he was subsequently unsealed by a manservant a little too quickly for anyone to forget about it, and is Enemy #1 of both the faction that sealed him away and the greater demon world who want him alive... to use as a tool to take power for themselves. With his extensive household of Just Two People, Lidius attempts to maintain a facade of status while managing the huge target on his back.

Luckily, he already has the power. He has a handle on it. The most important thing the people closest to him can do is keep up with the housekeeping.
